Thailand Complete Guide 2026: Bangkok, Phuket, Chiang Mai, Ayutthaya and Sukhothai

TL;DR

I have spent enough time in Thailand to say no other Southeast Asian country gives you this much variety for this little money. In one trip you can stand under the 46-metre reclining Buddha at Wat Pho in Bangkok, climb the 309 steps to Doi Suthep above Chiang Mai at 1,676 metres, snorkel inside Maya Bay on Koh Phi Phi (reopened January 2022 with a four-hour daily rotation), and wander the brick stupas of Ayutthaya, the royal capital sacked in 1767 and inscribed by UNESCO in 1991.

The biggest 2026 update is the visa-free rule. Since November 2023, Indian passport holders and many other nationalities receive 60 days visa-free on arrival, doubled from the old 30 days. Two months is finally enough time to do Bangkok, the north, the islands, and one historic capital without rushing.

The Thai baht has stayed broadly stable against the USD and INR through 2025 and into 2026, so the country remains affordable. A fan room in Chiang Mai costs 400 to 600 THB a night, pad krapao with a fried egg is 60 to 80 THB, and a Bangkok BTS ride is 17 to 47 THB. I have travelled here on budgets from 1,500 THB a day backpacker style to 6,000 THB a day mid-range and both work.

This guide covers five anchor regions (Bangkok, Chiang Mai, the Andaman coast around Phuket and Krabi, the Gulf islands of Samui and Pha Ngan, and the historic capitals of Ayutthaya and Sukhothai), three itineraries from 5 to 10 days, real costs in THB, USD and INR, eight FAQs, and honest notes the guidebooks skip.

Why Visit Thailand in 2026

The 60-day visa-free rule for Indian passport holders, in force since November 2023, is the single best reason to go now. Indians used to get 30 days and most travellers paid for an extension at immigration. Two months on a single stamp lets you do a slow loop without the visa-run pressure that used to define long Thailand trips.

The Thai baht has stayed steady against the USD and INR through 2025 and 2026. Tom yum at a Bangkok food court is 60 to 100 THB, a 12-hour overnight train from Bangkok to Chiang Mai in second-class air-conditioned sleeper is 800 to 950 THB, and an internal AirAsia flight from Bangkok to Phuket runs 1,200 to 2,500 THB if you book three weeks ahead.

Tourism numbers are back above 2019 peaks. Suvarnabhumi airport, the BTS, and inter-city buses run at full capacity. Maya Bay has been open since January 2022 with a four-hour daily rotation that protects the reef while still letting you swim. Chiang Mai has cracked down on elephant riding camps and ethical sanctuaries now outnumber them. If you have held off on Thailand since the pandemic years, 2026 is the cleanest window I have seen in a decade.

A Short History

Thai history starts with the Sukhothai kingdom, founded in 1238 and considered the first true Thai state. The Sukhothai era gave Thailand its alphabet, its Theravada Buddhist identity, and the walking Buddha style you still see in temple art. Sukhothai and its sister towns of Si Satchanalai and Kamphaeng Phet were inscribed together by UNESCO in 1991.

In 1351 power shifted south to Ayutthaya, which grew into one of the largest cities in the world by the 17th century. Ayutthaya traded with Persia, France, the Dutch, and the Chinese before the Burmese sacked it in 1767 and burned it. The ruins were also inscribed by UNESCO in 1991. A third UNESCO cultural site is Ban Chiang, a Bronze Age settlement in the northeast inscribed in 1992.

After 1767 General Taksin briefly held the kingdom together from Thonburi, and in 1782 Rama I founded the Chakri Dynasty and moved the capital across the river to Bangkok. The Chakri Dynasty still rules. Thailand is the only Southeast Asian country never formally colonized by a European power. In 1932 a bloodless revolution replaced absolute monarchy with a constitutional monarchy. The current king is Rama X, Maha Vajiralongkorn, who has reigned since 2016.

Tier-1 Destinations

Bangkok: Grand Palace, Wat Pho, Wat Arun and the Chao Phraya

Bangkok is the gateway. Give it at least three full days. The Grand Palace and Wat Phra Kaew, temple of the Emerald Buddha, are the first stop. The Emerald Buddha is a 66 cm jadeite figure whose seasonal robes the king ritually changes three times a year. Entry is 500 THB, the dress code is strict (covered shoulders and knees), and the complex opens at 08:30. Arrive at opening or you spend more time queuing than looking.

A 10-minute walk south brings you to Wat Pho, home of the 46 metre long, 15 metre tall reclining Buddha covered in gold leaf, with mother-of-pearl inlay on the soles showing 108 auspicious symbols. Wat Pho is the birthplace of traditional Thai massage and you can book an hour inside the temple grounds for 500 THB. Cross the river on the 4 THB Tha Tien shuttle to Wat Arun, whose 70-metre central prang is covered in broken Chinese porcelain that catches the sunset.

The Chao Phraya river is the best transport in old Bangkok. The orange-flag local boat is 16 THB and stops at every major temple pier. Khaosan Road is the backpacker artery, loud and cheap. Take the BTS to Chatuchak weekend market (Saturday and Sunday, 8,000+ stalls, go before 11:00), Jim Thompson House for the silk story, and the malls of Siam Paragon and MBK for air-conditioned relief. Skytrain rides are 17 to 47 THB. A Grab ride 6 km cross-town is 120 to 180 THB. Three days is the minimum.

Chiang Mai: Old City, Doi Suthep and Ethical Elephants

Chiang Mai is my favourite Thai city. The Old City is a 1.5 km square surrounded by moats and crumbling Lanna-era walls. Inside you find Wat Phra Singh (14th century, home of the Phra Singh Buddha image), Wat Chedi Luang with its half-ruined 60-metre stupa built in 1441, and dozens of smaller temples you stumble into. Entry to most temples is 20 to 50 THB.

The signature day trip is Doi Suthep, the mountain temple west of the city at 1,676 metres elevation. The final approach is the famous 309-step naga staircase. Wat Phra That Doi Suthep was founded in 1383 around a relic carried up the mountain by a white elephant. A red songthaew from the Old City costs 50 to 80 THB each way. Combine it with the Bhubing royal palace gardens if you are there November to February for the cool-season flowers.

The other Chiang Mai signature is the ethical elephant experience. Since around 2015 the city has moved firmly away from elephant riding. The sanctuaries I trust let you observe, feed, and bathe rescued elephants but do not allow riding or chains. Day visits run 2,000 to 2,800 THB including pickup and lunch. Confirm in writing that the sanctuary is no-ride and no-bullhook before booking. End the week at the Sunday Walking Street market on Ratchadamnoen Road, 16:00 to 22:30 every Sunday, the best place in the north for hill-tribe textiles, silver, and street food.

Phuket, Phi Phi and Maya Bay

Phuket is Thailand's biggest island and the main Andaman base. Patong is the loud beach with bars, tailors, and the Bangla Road night strip. Karon and Kata are quieter family beaches further south. I prefer Kata or Karon and day-trip to Patong only for one wild night. A Phuket airport transfer to Karon by Grab is 700 to 1,000 THB.

The main reason to come to Phuket is the boat trip to Phi Phi and Maya Bay. Maya Bay, made famous by the year-2000 film, was closed in 2018 because mass tourism had destroyed the coral. It reopened in January 2022 with a controlled four-hour daily rotation, a visitor cap, and a no-swimming-from-boats rule. You enter the beach from the back of the island through a wooden boardwalk. Speedboat day tours from Phuket to Phi Phi Don, Phi Phi Leh, Bamboo Island, and Maya Bay run 1,800 to 2,800 THB including lunch and snorkel gear.

If you have more time, take the ferry to Phi Phi Don and stay two or three nights. The viewpoint hike above Tonsai village (30 minutes uphill) is the best free thing on the island. Phi Phi has no roads or cars. Avoid the December to early January peak when Maya Bay slots sell out a week ahead.

Ayutthaya: UNESCO Historic Capital

Ayutthaya sits 80 km north of Bangkok and is the most rewarding day trip from the capital. The old city is on an island formed by three rivers and the ruins spread across 4 km of bicycle-friendly flat ground. UNESCO inscribed the historic city in 1991.

The single image everyone leaves with is the stone Buddha head wrapped in banyan tree roots at Wat Mahathat. You must crouch so your head is lower than the Buddha's when photographing it; a sign reminds you. Wat Phra Si Sanphet, the royal temple within the old palace grounds, has three restored chedis in a row that are the symbol of the site. Wat Chaiwatthanaram on the river bank is the best sunset spot. Combined entry is 220 THB or 50 THB per temple at each gate.

The easiest way to get there is the 3rd-class ordinary train from Krung Thep Aphiwat station for 15 to 20 THB, around 90 minutes. Bangkok hotels also sell van day-tours for 1,200 to 1,800 THB including lunch and a riverboat. Rent a bicycle for 50 THB outside the train station. Allow a full day, more if you add Bang Pa-In summer palace on the way back.

Sukhothai: First Thai Capital

Sukhothai is the deeper history stop, 430 km north of Bangkok, best done as an overnight on the way to Chiang Mai or via the small Sukhothai airport. The first true Thai kingdom was founded here in 1238 and the historical park covers 70 sq km of restored temples, lily ponds, and city walls. UNESCO inscribed Sukhothai with Si Satchanalai and Kamphaeng Phet in 1991.

The two temples to prioritize are Wat Mahathat, the main central complex with rows of Buddha figures and the famous lotus-bud chedi, and Wat Si Chum, a roofless square mondop containing a 15-metre seated Buddha called Phra Achana. You walk through a narrow passage and the Buddha appears suddenly through the gap. Entry to each zone of the park is 100 THB and bicycle rental is 30 THB a day.

Sukhothai is much quieter than Ayutthaya. Even in peak season you can sit alone in front of a 13th-century chedi for half an hour. New Sukhothai town is 12 km from the old park and has guesthouses for 400 to 800 THB. Time your visit to the Loy Krathong festival in November, which originated here and is celebrated with thousands of floating candles and lanterns set into the park ponds. One of the most beautiful nights in Asia.

Tier-2 Destinations

Krabi, Railay and Phra Nang Beach

Across the bay from Phuket on the mainland Andaman coast, Krabi province offers a quieter and more dramatic landscape. Railay peninsula is accessible only by longtail boat from Ao Nang or Krabi town because tall limestone cliffs cut it off from the road. Phra Nang Beach on the southern tip is one of the most photographed beaches in the world, with a sacred Princess Cave at one end and limestone karsts rising straight out of the water. Day trips to the Hong Islands lagoon and Tiger Cave Temple (Wat Tham Sua), with its 1,237-step climb to a hilltop shrine, fill out a 3-night Krabi stop.

Koh Samui and the Full Moon Party

Koh Samui is the Gulf coast counterweight to Phuket. The seasons are inverted (best weather January to August), Chaweng is the main beach, and the island is bigger and greener than Phi Phi. Forty minutes north by ferry is Koh Pha Ngan, home of the Full Moon Party held monthly on Haad Rin beach. The party draws 10,000 to 30,000 people on a good month. Even if you skip the party itself, Pha Ngan has beautiful quiet beaches on the west and north coasts (Bottle Beach, Mae Haad) that most visitors miss.

Koh Tao for Diving

A further hour north by ferry, Koh Tao is the cheapest place in the world to get a PADI Open Water dive certification. A 4-day Open Water course is around 9,800 to 11,500 THB including accommodation. The reefs are not the absolute best in Southeast Asia but the teaching infrastructure is unmatched, the visibility is good, and you can sometimes see whale sharks at Chumphon Pinnacle.

Khao Sok Rainforest

Khao Sok National Park on the mainland between the two coasts is one of the oldest rainforests on Earth, older than the Amazon. The signature experience is an overnight stay on a floating raft house on Cheow Lan Lake, surrounded by limestone karsts that look like a flooded version of Halong Bay. Two-day, one-night packages run 4,500 to 6,500 THB including all meals, the boat, and a guided morning safari.

Pattaya

Pattaya, 150 km southeast of Bangkok, is a complicated destination. It has a frank adult nightlife reputation that I will not detail here. But it also has the Sanctuary of Truth (a fully hand-carved teak temple still being built since 1981), the Nong Nooch tropical garden, and family-friendly beaches at Jomtien. A day trip from Bangkok is enough for most travellers.

Costs in THB, USD and INR

PADI Open Water Koh Tao 9,800 to 11,500 282 to 330 23,500 to 27,600

Conversions use approximate rates of 1 USD = 34.7 THB and 1 INR = 0.42 THB current to early 2026. The baht has held this range for most of 2025, which makes pre-trip budgeting more reliable than it has been for currencies elsewhere in the region.

Planning the Trip

The most important planning decision is the season. November to February is the cool, dry, peak season. Daytime temperatures sit at 26 to 32 C, humidity drops, and the air is clear. This is when you want to do Bangkok, Chiang Mai, and the historic capitals. Book two months ahead for December and early January.

March to May is the hot season. Bangkok regularly hits 38 C with heavy humidity. This is the worst time for cities and a good time for islands. Songkran, the Thai New Year water festival, runs 13 to 15 April nationwide. Expect everyone to be soaking everyone with water guns for three days. Phones in waterproof pouches, no exceptions.

June to October is the rainy season. The pattern differs by coast. The Andaman side (Phuket, Krabi, Phi Phi) gets heavy monsoon from May through October. The Gulf side (Koh Samui, Pha Ngan, Koh Tao) has its main rain later, October to December. So if you want islands in September, go Samui not Phuket. Rain usually comes in afternoon downpours rather than all-day grey.

For internal travel, I use AirAsia, Thai Lion Air, Nok Air and Thai Vietjet for flights, the State Railway for trains, and 12go.asia for buses and ferries. For SIMs, AIS and TrueMove offer tourist eSIMs with 15 GB for 7 days at 200 to 300 THB and 30 GB for 30 days at 700 to 900 THB.

Bring sunscreen from home. Thai pharmacy sunscreen often contains whitening agents and is expensive. Bring a quick-dry towel, modest temple clothing (long pants or sarong, covered shoulders), and a power bank for long ferry days.

FAQs

Do Indians need a visa for Thailand in 2026?
No. Since November 2023, Indian passport holders receive 60 days visa-free on arrival, doubled from the previous 30 days. You still need a passport with 6 months validity, proof of onward travel, and proof of funds (10,000 THB per person, rarely checked).

Is it ethical to ride elephants in Thailand?
No, and most reputable sanctuaries no longer offer it. Choose sanctuaries that explicitly market themselves as no-ride, no-hook, observation and feeding only. Get the policy in writing before paying.

Is Maya Bay open in 2026?
Yes. Maya Bay closed in 2018 for coral and beach recovery and reopened in January 2022 with a four-hour daily rotation and a visitor cap. You cannot anchor in the bay or swim in from boats. Access is from the back of the island via a boardwalk.

Is the food safe at street stalls?
Yes, mostly. Choose stalls with high turnover where ingredients cook in front of you. Avoid raw salads at unfamiliar places, peel your own fruit, and drink only bottled water.

Are there good vegetarian options?
Yes. Ask for "jay" (เจ), the strict vegan Buddhist tradition with no animal products and no strong-smelling vegetables. The October Jay Festival in Phuket and Bangkok is when jay food is everywhere.

Is Thailand safe for solo female travellers?
Generally yes. Petty theft is the main risk. Use Grab over tuk-tuks at night, do not leave drinks unattended in Bangla Road or Khao San Road bars, and dress modestly for temples.

What are the common scams?
The closed-Grand-Palace tuk-tuk scam (driver claims the palace is shut and runs a gem-shop tour), the jet ski damage scam in Phuket, over-priced suit tailoring, and the taxi meter "broken" claim. Insist on the meter or use Grab.

Can I criticize the king on social media?
No. Thailand enforces lèse-majesté laws under Section 112. Public comments deemed insulting to the monarchy carry serious prison sentences and apply to foreigners. Do not step on banknotes (they carry the king's image) and avoid political commentary online while in the country.

Useful Thai Phrases

Thai Meaning
Sawatdee kha (female) / Sawatdee khrap (male) Hello
Khob khun kha / khob khun khrap Thank you
Karunaa Please
Tao rai? How much?
Phaeng pai Too expensive
Mai pen rai No problem / never mind
Aroi mak Very tasty
Chok dee / Chai yo Good luck / cheers
Mai phet Not spicy
Hong nam yu thi nai? Where is the toilet?

The female speaker ends sentences with "kha" and the male speaker with "khrap." Using either with a stranger goes a long way.

Cultural Notes

Thailand is around 95% Theravada Buddhist and Buddhist practice shapes daily life. Monks in orange robes are everywhere, especially at dawn during alms rounds. Three rules keep you respectful inside temples. Cover shoulders and knees, remove shoes before entering any building containing a Buddha image, and never point your feet at a Buddha or another person. The feet are considered the lowest part of the body, the head the most sacred. Do not touch a Thai person on the head, and do not sit with your soles pointing toward a Buddha or a monk. Women should not touch a monk or hand anything directly to one.

The royal family is revered and legally protected. Section 112 lèse-majesté laws are enforced and apply to foreigners. Do not joke about, criticize, or speculate publicly about the monarchy. Stand still when the royal anthem plays at 08:00 and 18:00 in train stations and public squares.

The main festivals are Songkran (Thai New Year, 13 to 15 April) and Loy Krathong (full moon of the 12th lunar month, usually November), when small lotus rafts with candles are released onto rivers and lakes. Sukhothai is the most beautiful place to see Loy Krathong. The Yi Peng lantern release in Chiang Mai falls around the same time.

Food is the daily anchor. Tom yum goong, pad thai, green and red curries, pad krapao, mango sticky rice, and som tam are worth ordering twice. Thai food in Thailand is spicier than the export version. Say "mai phet" (not spicy) or "phet nit noi" (a little spicy). Muay Thai is the national sport. A ringside seat at Rajadamnern or Lumpinee stadium in Bangkok is 1,500 to 2,000 THB.

Pre-Trip Checklist

Passport with 6 months validity beyond your travel dates. Proof of onward travel (the airline at check-in often asks even though immigration rarely does). One copy of passport stored separately. Travel insurance with medical and evacuation cover (Thailand has good private hospitals but they are expensive without insurance). Hepatitis A, typhoid and tetanus vaccines confirmed up to date. A modest temple outfit (long pants or sarong, covered shoulders). Sunscreen from home. A small first aid kit with rehydration salts. A power bank. eSIM ready to activate on landing. Around 5,000 THB in cash for the first 48 hours. Grab app installed and a working international payment method linked.
