Best Palauan Rock Islands (UNESCO 2012), Yap Stone Money, Pohnpei Nan Madol (UNESCO 2016, in-danger), and Jellyfish Lake: A Deep Pacific Heritage Tour Across Micronesia

I planned this trip over two years and still felt unprepared when the United Airlines Island Hopper banked over Koror at sunrise. Micronesia is a country count problem disguised as a region. Palau is one independent state. The Federated States of Micronesia (FSM) is another, made up of Yap, Chuuk, Pohnpei, and Kosrae. Both use the US dollar, both are tiny by population, and both hold UNESCO sites that punch far above the region's size on a world map. This guide is the long version of what I wish someone had handed me before I bought the ticket.

TL;DR

I spent ten days moving across the Pacific by short flights and small boats, and I came back convinced Micronesia is the most under-visited UNESCO-rich region on Earth. Palau's Rock Islands Southern Lagoon was inscribed on the UNESCO World Heritage List in 2012 as a mixed cultural and natural property covering 445 limestone karst islands across roughly 100,200 hectares of lagoon. Nan Madol, on Pohnpei in the FSM, was inscribed in 2016 and added to the World Heritage In Danger list the same year due to mangrove overgrowth and structural instability across its 92 artificial basalt islets. Yap is the only place where stone money discs (Rai), some up to 4 m in diameter and mined 400 km away in Palau by outrigger canoe between the 17th and 19th centuries, still change hands ceremonially. Jellyfish Lake on Eil Malk Island reopened to swimmers in 2018 after a 2016 closure caused by a population crash, and the golden Mastigias jellies are back in the millions. Chuuk Lagoon, 40 km by 32 km, holds more than 60 Japanese ships and 270 aircraft sunk during Operation Hailstone on 17-18 February 1944, making it the most concentrated WWII wreck dive site on the planet. Budget travelers will struggle here. Flights are the largest line item, with the Island Hopper service costing around USD 2,000 round trip from Honolulu to Guam with stops at Majuro, Kosrae, Pohnpei, and Chuuk. Inside Palau, the Rock Islands permit costs USD 100 and the general state permit adds USD 50 to USD 100 depending on activity. A two-tank dive at Blue Corner runs USD 130 to USD 150. Yap charges around USD 35 for a stone money village visit and USD 150 to USD 220 for a manta ray dive between December and April when the animals aggregate in Mil Channel and Goofnuw Channel. Pohnpei's Nan Madol entry is USD 5 plus a USD 5 boat fee from Madolenihmw. English is widely spoken alongside Palauan, Yapese, Pohnpeian, Kosraean, Chuukese, and several outer island languages. The US dollar is the only currency in both countries, ATMs work in Koror and Pohnpei but are patchy elsewhere, and most outer islands run cash only. The dry travel window is roughly December to April, though it rains in flashes year round. Plan a 7-10 day Micronesia trip.

Why Micronesia matters

Two UNESCO sites in one region, both rare, both endangered, and both impossible to confuse with anything else on the planet. Palau Rock Islands Southern Lagoon (UNESCO 2012, mixed cultural and natural) is one of the few mixed sites in the Pacific, recognized for 445 uplifted Miocene-age limestone karst islands, marine lakes, coral reefs, and an unbroken archaeological record going back 5,000 years that includes rock art, burial caves, and abandoned villages from the late Yapese-era period. Nan Madol (UNESCO 2016, In Danger) is the only ancient city in Oceania built out of megalithic basalt prisms, 92 artificial islets totalling more than 18 square kilometers in extent on the southeast reef of Pohnpei. Add Jellyfish Lake, with its roughly 5 million golden Mastigias jellies that lost their sting because they were isolated from the ocean about 12,000 years ago, and Yap's stone money, which is the only currency on Earth where ownership of a 4 m, multi-ton disc is transferred verbally without anyone moving it. The Federated States of Micronesia is a single country made of four states, Yap, Chuuk, Pohnpei, and Kosrae. Palau is a separate independent state that left the FSM negotiations and became fully independent on 1 October 1994, ending the longest UN trusteeship in history. Both use the USD, both run on Compacts of Free Association with the United States, and both have populations under 105,000. That is fewer people than a mid-size US suburb spread across an ocean area larger than the continental United States.

Background

Austronesian seafarers reached the western Caroline Islands around 1500 BC, part of the Lapita cultural complex that also seeded Polynesia. By 1180 AD, the Saudeleur Dynasty had consolidated political power across Pohnpei and begun construction of Nan Madol on the reef flats of the island's southeastern coast. Saudeleur rule lasted roughly 450 years and ended around 1628 with the invasion led by Isokelekel, a semi-legendary Kosraean warrior whose chiefdom system, the Nahnmwarki, survived into the modern era and still holds traditional authority on Pohnpei today.

European contact began with the Spanish in the 16th century, formalized when Spain claimed the Caroline Islands in 1686. Spain sold the Carolines and the Marianas (minus Guam) to the German Empire on 30 June 1899 for 17 million gold marks. The Empire of Japan seized the islands in October 1914 at the start of World War I and held them as the South Pacific Mandate under the League of Nations from 1919 onward. Japanese settlers eventually outnumbered the indigenous population on Saipan, Palau, and parts of Chuuk before the Pacific War broke out.

The Battle of Chuuk Lagoon, code-named Operation Hailstone, lasted from 17 to 18 February 1944. US Task Force 58 sank more than 60 ships and destroyed roughly 270 aircraft in two days, ending Chuuk's role as the "Gibraltar of the Pacific" and creating the wreck graveyard that draws technical divers today. After 1945, the islands became the US-administered Trust Territory of the Pacific Islands under United Nations Trusteeship Council oversight from 1947 to 1986. The FSM ratified its constitution on 10 May 1979 and became independent on 3 November 1986 under a Compact of Free Association with the United States. Palau followed on 1 October 1994 after several rejected referenda over a constitutional clause banning nuclear weapons.

• Lapita arrival: roughly 1500 BC across western Carolines
• Saudeleur Dynasty on Pohnpei: 1180-1628 AD, ended by Isokelekel
• Spanish claim: formalized 1686, sold to Germany 30 June 1899
• Japanese South Pacific Mandate: 1914-1945, civilian rule from 1919
• Operation Hailstone: 17-18 February 1944, more than 60 ships sunk
• US Trust Territory: 1947-1986, longest UN trusteeship in history
• FSM independence: 3 November 1986; Palau independence: 1 October 1994

Tier 1: 5 destinations I'd plan a whole trip around

Palau Rock Islands Southern Lagoon (UNESCO 2012)

I took my first boat out of Sam's Tours in Koror at 7:30 AM and the Rock Islands looked exactly like the photographs everyone has seen, except louder. 445 mushroom-shaped limestone karst islands rise out of turquoise water across roughly 100,200 hectares of protected lagoon. The undercut bases come from millennia of tidal erosion and grazing chitons, which is why the islands look like green hats balanced on white stems. Most of the renowned islands sit within the Ngerukewid Islands Wildlife Preserve, a seven-island marine reserve declared in 1956 and closed to landings, so most visitors view it from the boat.

The hero sites inside the lagoon are Milky Way, a sheltered inlet where the seafloor is covered in a fine, white, mineral-rich limestone mud that locals scoop up and smear on as a spa treatment, and the diving wall at Big Drop Off, which falls from the surface to over 300 m within a few fin kicks of the reef. Blue Corner is the dive that landed Palau on every world top-ten list since the 1990s. Strong currents pin you to a hooked-in position on the reef while sharks, jacks, and Napoleon wrasse stream past. Expect to pay USD 130 to USD 150 for a two-tank Blue Corner dive with a local operator like Sam's Tours, Fish 'n Fins, or Neco Marine.

Permits stack up quickly. The Koror State Rock Islands Use Permit costs USD 50 for one day or USD 100 for ten days, and the Jellyfish Lake permit adds another USD 100 if you want that combo. The national Pristine Paradise Environmental Fee, collected when you depart at Roman Tmetuchl International Airport (ROR), is USD 100 per person. Koror itself is small, around 14,000 residents, and you can walk most of it in an afternoon. The Belau National Museum, founded in 1955 as the oldest museum in Micronesia, is the right starting point before any boat trip.

Jellyfish Lake and Rock Islands snorkeling

Jellyfish Lake sits in the middle of Eil Malk Island (Mecherchar) about 45 minutes by speedboat south of Koror. The lake is one of more than 70 marine lakes in the Rock Islands and the only one currently open to swimmers. Roughly 5 million golden Mastigias papua etpisoni jellies and a smaller population of moon jellies (Aurelia) drift across the lake daily, following the sun in a clockwise loop. Their stinging cells became vestigial after the lake was cut off from the ocean about 12,000 years ago, so you can swim through them without any reaction stronger than a soft brush.

The lake closed in 2016 because the jelly population crashed from roughly 8 million to under 600,000 during an El Nino-driven warm spell. The Koror State Government reopened it to controlled visits in 2018 once monitoring confirmed the population had recovered past 5 million. Today the rules are strict. No scuba (only snorkeling), no sunscreen (it kills the symbiotic algae the jellies depend on, so you wear a rash guard instead), and no fins (kicking damages the jellies). A standard Jellyfish Lake day tour out of Koror costs USD 100 to USD 130 including the boat, permits, and lunch, usually paired with stops at Milky Way and a Rock Islands snorkeling site like Cemetery Reef. I'd block out 8 hours door to door.

Yap stone money and traditional culture

Yap is the most culturally intact place I have ever visited. The flight from Koror to Yap International Airport (YAP) takes one hour on United Airlines, which runs about three flights a week. Roughly 13,000 Yapese live on the main island group, and stone money (rai) is still functioning ceremonial currency. The discs are quarried from aragonite limestone in Palau, 400 km southwest. Yapese sailors carried them on bamboo rafts behind outrigger canoes between roughly the 17th and early 20th centuries, an undertaking with a high enough mortality rate that the trip itself increased a stone's value. Around 6,000 rai stones survive, ranging from a few centimeters to over 4 m across and weighing up to 4,000 kilograms.

What I did not understand until I was there is that the stones almost never move. Ownership transfers verbally in a conversation witnessed by the village, with the stone staying in its original "bank" along a stone money path. Balebat village near Colonia hosts the most accessible stone money bank, a quiet line of vertical discs along a forested trail, and a village visit fee of around USD 10 to USD 35 supports the community. You will also see traditional thu loincloths worn by men and grass skirts on women in cultural contexts, especially around the faluw men's houses and pebay community houses.

Yap's other claim is manta ray diving. Between December and April, large reef mantas (Mobula alfredi) with wingspans up to 4 m aggregate at cleaning stations in Mil Channel on the north coast and Goofnuw Channel on the east side. Dives run USD 150 to USD 220 a day with operators like Manta Ray Bay Resort, the only dive shop on the island that's been running since 1986. February sightings approach a 95% success rate.

Pohnpei and Nan Madol (UNESCO 2016, In Danger)

Pohnpei is a high volcanic island, 334 square kilometers, ringed by mangroves and laced with waterfalls. Kolonia is the small capital town, about 6,000 residents, and the airport (PNI) sits on Deketik Island connected by causeway. Nan Madol lies about 25 km southeast on the reef flats off Madolenihmw municipality. The site is 92 artificial islets built between roughly 1180 and 1628 AD by stacking prismatic basalt columns, each weighing up to 5 tons, in a log-cabin pattern on coral foundations. The total complex covers about 18 square kilometers when you include the seaward breakwater and inland staging areas. The columns came from quarries on the opposite side of Pohnpei, and how they were moved across the island without wheels, pulleys, or draft animals is still genuinely unexplained, with rope-and-raft theories dominating the academic literature.

Entry to Nan Madol costs USD 5, with an additional USD 5 boat fee at the Madolenihmw landing, and you need a local guide both for permission from the Nahnmwarki and for safety reasons. The site is overgrown with mangrove roots, the tidal channels between islets fill and drain quickly, and saltwater crocodiles have been sighted in the outer canals since at least 2014. Bring DEET, long sleeves, and reef shoes. The In Danger listing in 2016 reflects mangrove encroachment, basalt collapse from root pressure, and saltwater intrusion eating at the column bases. UNESCO and Japan-funded conservation projects since 2018 have started clearing key islets like Nandauwas, the royal mortuary, where the walls still rise 7.6 m high.

Chuuk Lagoon and Operation Hailstone diving

Chuuk Lagoon, formerly known as Truk Lagoon, is 40 km east to west by 32 km north to south, ringed by a 225 km barrier reef enclosing 2,130 square kilometers of water. It is the largest natural lagoon in the Pacific and one of the largest in the world. The main island, Weno (formerly Moen), holds Chuuk International Airport (TKK) and around 14,000 of the lagoon's 50,000 residents. During WWII it was the headquarters of the Imperial Japanese Navy's Combined Fleet, dubbed the "Gibraltar of the Pacific," until US carrier aircraft from Task Force 58 destroyed it on 17-18 February 1944.

Operation Hailstone sank more than 60 ships, totaling over 200,000 tons of shipping, and destroyed roughly 270 aircraft. The lagoon is now the densest concentration of WWII wrecks on Earth, almost all of them within recreational or technical diving range between 10 m and 60 m. The Fujikawa Maru, an aircraft ferry sitting upright at 18-34 m, is the classic first dive, with intact Zero fighter fuselages still in the hold. The Shinkoku Maru, a 10,520 ton fleet oiler at 12-38 m, is famous for soft coral growth across the entire hull. The Heian Maru at 16-33 m is the largest submarine tender in the lagoon at 155 m length, with long lance torpedoes still in the racks. Daily two-tank dives run USD 150 to USD 220 with Blue Lagoon Dive Shop or the Truk Stop, and full technical operations on the deeper wrecks like the San Francisco Maru can run USD 250 to USD 350 a day. Chuuk is dive-only as a destination. There is almost no land tourism infrastructure.

Tier 2: 5 more places worth your time

• Kosrae, the easternmost FSM state, is a 110 square kilometer high island with the Lelu Ruins, a smaller basalt-walled city built between roughly the 13th and 19th centuries by the Kosraean kings, plus jungle treks up Mount Finkol (619 m) and uncrowded reef dives at Yela.
• Babeldaob is Palau's largest island at 331 square kilometers, connected to Koror by the Japan-Palau Friendship Bridge since 2002. The 53 km Compact Road circles the island past the new Capitol Complex in Ngerulmud, opened in 2006, and gives you waterfalls like Ngardmau (30 m drop) and abandoned Japanese WWII airfields.
• Peleliu, in southern Palau, was the site of the Battle of Peleliu from 15 September to 27 November 1944, where US Marines and Army took over 10,000 casualties. The island is dotted with rusting Sherman tanks, the abandoned Japanese command bunker, and the 1,000-Man Cave.
• Angaur is the southernmost main island in Palau, with German-era bauxite mining ruins from 1909-1914, WWII Japanese fortifications, and an introduced population of long-tailed macaques brought in during the German period.
• Sokehs Rock, a 200 m basalt monolith on Pohnpei across the harbor from Kolonia, is the eroded plug of an ancient volcano and a 2-3 hour hike with one of the best panoramic views in Micronesia.

How to plan it

Flights and the Island Hopper. The single most distinctive way into the region is the United Airlines Island Hopper, flight UA 154/155, which runs roughly five times a week between Honolulu (HNL) and Guam (GUM) with intermediate stops at Majuro (MAJ) in the Marshall Islands, Kosrae (KSA), Pohnpei (PNI), and Chuuk (TKK). The full one-way trip is around 14 hours with five stops, and a round trip Honolulu-Guam costs USD 1,800 to USD 2,200 in economy. From Guam, separate United flights connect to Yap (YAP) about three times a week (around USD 350 one way) and Palau's Roman Tmetuchl International Airport (ROR) daily (USD 250 to USD 400 one way). Korean Air flies Incheon to Palau directly four times a week at around USD 600 to USD 900 round trip from Seoul.

Weather and season. Both countries sit between 5 and 10 degrees north latitude, so it is tropical and hot year round, with average highs of 30 to 32 Celsius and lows of 23 to 25 Celsius. The drier and calmer window is December through April. May through November is wetter and runs the risk of typhoons, especially in Yap and Chuuk, which sit closer to the typhoon belt. Palau is south of the main typhoon track but does get hit occasionally, the most destructive being Typhoon Bopha in 2012 and Surigae in 2021.

Languages. English is the official language of both countries and is widely spoken in towns and tourism settings. You will also hear Palauan in Palau, and Yapese, Pohnpeian, Chuukese, Kosraean, plus outer-island languages like Ulithian, Woleaian, Nukuoro, and Kapingamarangi across the FSM. That's why FSM is sometimes described as having more than 9 distinct languages on top of English.

Currency and ATMs. Both countries use only the US dollar. ATMs work reasonably well in Koror, Kolonia, and Weno but charge USD 5 to USD 7 per withdrawal. Yap and Kosrae have one or two reliable ATMs each in the main town. Outer islands and many dive operators run cash-only, so I carried about USD 800 in clean small bills.

Visas. Palau allows visa-free entry for one year for US passport holders under the Compact, 90 days for most EU and ASEAN passports, and 30 days for most other nationalities including India, with extensions possible at the immigration office in Koror. FSM offers 30 days visa-free for most nationalities including India, extendable to 60 days at the immigration office in Pohnpei. Always confirm directly with the embassy or the country's official immigration website before booking. The Palau Pristine Paradise Environmental Fee, USD 100, is collected at airport departure and is non-negotiable.

Health and insurance. No yellow fever risk if arriving from a non-endemic country. Malaria risk is essentially zero. Dengue does flare up seasonally, especially in Chuuk and Pohnpei, so I packed picaridin and a long-sleeve UV shirt. Decompression chamber coverage is the one insurance line I obsess about. The nearest chamber is in Koror for Palau; Guam handles most FSM emergencies, so DAN World coverage at USD 90 a year is the right call for any diver.

FAQ

1. How long should I plan for a first Micronesia trip?
I'd commit to 10 days minimum if you want both UNESCO sites. A workable structure is 4 nights in Koror for Palau Rock Islands and Jellyfish Lake, 2 nights in Yap for stone money and manta dives, 3 nights in Pohnpei for Nan Madol and Sokehs Rock, with the Island Hopper handling the connections. Anything shorter forces you to pick one country, and the flight time from Honolulu or Guam makes that painful. If you only have 7 days, focus on Palau alone. 14 days lets you add Chuuk and Kosrae and run the entire Island Hopper.

2. Is the Island Hopper actually worth doing as an experience?
For me, yes. The Honolulu-Guam Island Hopper takes about 14 hours with five intermediate landings at Majuro, Kosrae, Pohnpei, Chuuk, and finally Guam. You stay on the same aircraft for the whole trip, but you can disembark at each stop for 30 to 60 minutes to walk the apron and visit the small terminals. It is the only commercial passenger flight in the world that still operates like a 1960s milk run. Book a window seat on the south side. Reef colors at Kosrae and Pohnpei are unlike anything from regular jet altitude. Round trip costs around USD 1,800 to USD 2,200 in economy.

3. Can I really swim with millions of jellyfish without getting stung?
Yes, with one nuance. Jellyfish Lake reopened in 2018 after a closure that began in 2016 because the population had crashed from a strong El Nino. Today around 5 million golden Mastigias and a smaller moon jelly population are back. Their nematocysts (stinging cells) are too small to penetrate most human skin and the mild stinging proteins were lost over 12,000 years of isolation. You will feel soft brushes and the occasional ticklish touch around the face. Sensitive people may get faint hives. Rules now include no scuba, no fins, no sunscreen, and a USD 100 Jellyfish Lake permit on top of the Rock Islands fee.

4. How does stone money etiquette actually work for visitors?
You never touch a Rai disc without explicit permission from the village chief, and you never sit on one. Photographs are usually fine in the major stone money banks at Balebat, Riy, and Okaw with a village contribution of USD 10 to USD 35 per visitor. Ownership of a stone transfers verbally during ceremonies witnessed by the village, and the stones rarely move. Your guide will explain which discs belong to whom and which carry stories about lost lives during the canoe transport, which gives them extra ceremonial value.

5. Is Nan Madol dangerous to visit?
Risk is real but manageable. Mosquito density is high, so wear long sleeves and DEET. Saltwater crocodiles have been documented in the outer canals since at least 2014, so do not swim in the canals or wade outside the main visitor path. Walking surfaces are uneven basalt rubble, slick with algae at low tide. Always go with a licensed local guide arranged through Madolenihmw municipality. Entry is USD 5 plus USD 5 for the boat. The royal mortuary Nandauwas, with its 7.6 m walls, is the worth seeing islet, and the conservation work funded by Japan since 2018 has cleared its core area of invasive mangrove.

6. How does diving in Chuuk Lagoon compare to Palau?
They are complementary rather than competing. Palau is big-fish drift diving on healthy reefs at sites like Blue Corner, Ulong Channel, and German Channel, with strong currents and a high chance of sharks, mantas, and Napoleon wrasse. Chuuk is wreck diving, much more historical, often with mild currents and reduced visibility (15-25 m) compared to Palau (25-40 m). Most Chuuk dives are between 15 m and 40 m on classic wrecks like Fujikawa Maru, Shinkoku Maru, Heian Maru, and Nippo Maru. Technical divers go deeper to the San Francisco Maru at 50-60 m. Daily dive cost is similar at USD 150 to USD 220 with land-based operators, more on liveaboards.

7. What should I budget for a 10-day Palau plus Yap plus Pohnpei trip?
A realistic mid-range budget excluding the international flight to Honolulu or Guam is roughly USD 4,500 to USD 6,500 per person. That breaks down to about USD 1,800 for Island Hopper and intra-region flights, USD 1,800 for hotels at USD 180 a night average, USD 700 for diving and Rock Islands tours, USD 400 for food, USD 250 in permits and the USD 100 Palau departure fee, and USD 350 for ground transport, guides, and tips. Budget travelers using guesthouses and skipping dives can drop to roughly USD 3,000, but expect tight rooms and limited cooling.

8. Is Micronesia safe for solo travelers and for women specifically?
Generally yes, with caveats. Violent crime against tourists is rare across both Palau and the FSM. Petty theft happens around Koror nightlife and Weno, so keep cash and passports in your room safe. Modesty norms are strong in Yap, where many local women still wear traditional grass skirts and go bare-chested in village settings. Visitors should cover shoulders and knees outside the resort areas. Chuuk has alcohol restrictions in some municipalities that limit late-night activity, which actually makes evenings calmer for solo travelers. Bring a satellite communicator if you plan island-hopping outside the main hubs.

Local phrases and cultural notes

A few words make a real difference in how you are received.

• Palauan: Alii (hello), Ungil tutau (good morning), Sulang (thank you), Ak mocha (I am going), Ngarang a ngklem? (what's your name?).
• Yapese: Mogethin (hello), Salgad (goodbye), Kammagar (thank you), Kefel (good, OK), Gaay rogon? (how are you?).
• Pohnpeian: Kaselehlie (hello), Kalahngan (thank you), Menlau (please), Ia iromw? (how are you?).
• Chuukese: Ran annim (hello), Kinisou (thank you), Iei usun? (how are you?).

Cultural notes I learned the hard way. In Palau, the traditional bai meeting houses (most famous at Airai, with carved gables dated to roughly 1890) are sacred. Take photos only with permission. Palauan tom-tom drum dances and the Ngloik women's dance are performed at major village events. In Yap, the faluw men's house is restricted to men of the village. Women should never enter or sit in front of one without explicit invitation, and visitors of any gender should not photograph it without consent. Pohnpei's sakau (kava in other parts of Oceania), prepared from Piper methysticum on a hibiscus bark strainer, is offered at most evening gatherings. Accepting a coconut cup is a sign of respect; sipping slowly and offering the next round back is the correct response. Across the region, modesty matters more than in Bali or Phuket. Cover shoulders and knees in villages, save swimwear for the boat and the resort, and remove shoes when entering any home, church, or traditional building.

Pre-trip prep

• Visas and entry. Palau is visa-free 30-365 days depending on passport. FSM is 30 days visa-free for most nationalities, extendable to 60 days at Pohnpei immigration. India passport holders get 30 days at both countries on arrival. Carry proof of onward travel and a hotel reservation in case of immigration questions. The Palau Pristine Paradise Environmental Fee of USD 100 is paid at departure at ROR and is non-refundable.
• Power and plugs. 120V at 60Hz with Type A and Type B (US) plugs across both Palau and the FSM. No adapter needed if you carry US-style plugs. Power cuts are common in Chuuk and Yap; a power bank of 20,000 mAh and a small inverter helps.
• Connectivity. Palau Cellular (PalauTel) sells SIM cards from USD 30 to USD 50 with limited 4G coverage in Koror and weak signal across Babeldaob. FSM Telecom prepaid SIMs cost USD 25 to USD 45 with 4G in Pohnpei, Chuuk, Yap, and Kosrae main islands but weak coverage everywhere else. Starlink residential terminals have spread to Koror, Kolonia, and Weno since 2024 and many hotels now advertise Starlink Wi-Fi. Download offline maps before you fly.
• Cash. USD only, both countries. Bring USD 600 to USD 1,000 in clean small bills (USD 5, USD 10, USD 20). Outer islands and most dive operators charge cash. ATMs at Koror, Kolonia, and Weno work but charge USD 5 to USD 7 per withdrawal.
• Reef-safe sunscreen is mandatory in Palau. Palau banned reef-toxic sunscreens (oxybenzone, octinoxate, and eight other ingredients) on 1 January 2020, the first country in the world to do so. Customs will confiscate non-compliant bottles. Bring zinc oxide or titanium dioxide based sunscreen, and a long-sleeve rash guard solves most of the problem.
• Health. No malaria. Dengue exists, especially in Chuuk and Pohnpei. Recommended vaccines per CDC: routine plus hepatitis A, typhoid, and hepatitis B for divers and longer stays. DAN World dive insurance at USD 90 a year is essential. The nearest hyperbaric chamber for Palau is in Koror; for FSM it is functionally Guam, around 1,300 km from Chuuk.
