Comoros Travel Guide 2026: Moroni, Grande Comore, Anjouan, Mohéli & the Perfume Islands

TL;DR

I spent close to three weeks across the Comoros archipelago in 2026 and came home convinced this is the most under-visited corner of the Indian Ocean. The four-island chain sits between Mozambique and Madagascar, with three islands (Grande Comore, Anjouan, Mohéli) forming the Union of the Comoros and a fourth, Mayotte, remaining a French overseas department since 2011. Highlights for me: climbing the 2,361m Mt Karthala with its 3 km wide summit crater, the largest active volcano crater in the world; snorkelling inside the Mwali Marine Park, a UNESCO Biosphere Reserve since 2003; visiting the Friday Mosque Ancienne in Moroni, built in 1457; walking the 17th-century citadel above Mutsamudu on Anjouan; and learning how 80% of the world's ylang-ylang supply still leaves these islands for perfume houses in France. Visa-on-arrival costs USD 30 for 30 days for most nationalities, including Indian passport holders, with proof of onward travel and accommodation. The population sits near 850,000 across the three independent islands, GDP per capita hovers around USD 1,500, and the country is one of the poorest in Sub-Saharan Africa, so come prepared, bring crisp USD cash, and travel slowly.

Why Visit Comoros in 2026

I went because almost nobody else does. In a single trip I climbed an active volcano, swam with green sea turtles in a UNESCO Biosphere, drank cardamom tea with a fisherman whose grandfather caught one of the first recorded coelacanths in 1952, and walked through a 1457 mosque older than most European cathedrals. The visa is straightforward, the landings are short hops from Nairobi or Dar es Salaam, and prices stay reasonable if you avoid the few European-style hotels.

For 2026 specifically, three factors line up. First, the visa-on-arrival fee remains USD 30 for a 30-day stay, with onward travel and hotel confirmation the only paperwork I needed at Hahaya International. Second, the Mwali Marine Park has expanded community-run lodges around Nioumachoua, so seeing humpback whales between July and September no longer requires a private charter. Third, Mt Karthala, the 2,361m stratovolcano on Grande Comore, has had no major eruption since April 17, 2007, and the trail network from Nyumba Mvua is in better condition than locals remember, though a permit through Karthala National Park (gazetted in 2010) is still mandatory.

The country also keeps its position as one of the world's main coelacanth (Latimeria chalumnae) habitats. The species, often called a living fossil and dated to roughly 400 million years old, was thought extinct until a specimen was caught off the South African coast in 1938, with the main living population later confirmed off the Comoros in 1952. Researchers estimate 350-400 individuals here, each over a metre long, with lobed fins that resemble the limbs of early tetrapods.

Background: From Bantu Migration to 22 Coup Attempts

The islands are young geologically and old culturally. The oldest landmass, around 15 million years old, is what we now call Mayotte, while Grande Comore is closer to 1,500 years old in volcanic terms, with Mt Karthala still active. Human settlement started with Bantu migration in the 6th century CE, joined later by Austronesian seafarers from what is now Indonesia, Arab traders from the 9th century onward, and Shirazi Persians who arrived around the 11th century and founded several sultanates.

Portuguese navigator Tristão da Cunha reached the archipelago in 1505, and over the next three centuries a patchwork of sultanates ran the islands from the 15th to the 19th century, often deeply involved in the western Indian Ocean slave trade. The French signed a protectorate treaty over Mayotte in 1841, expanded to Anjouan and the rest of the islands through the 19th century, and absorbed Grande Comore and the wider Comoros into a full French colony in 1912.

A self-determination referendum in 1974 produced a 95% yes vote across three of the four islands, and on July 6, 1975, the Union of the Comoros declared independence. Mayotte voted to remain French and stayed under French administration, a position formalised when it became a French overseas department in 2011. Independence did not bring stability: locals quote 22 coup attempts in the first 30 years of independence, several of them led by the French mercenary Bob Denard. Ahmed Abdallah served as president from 1978 until his assassination in 1989. Ahmed Abdallah Sambi held office between 2006 and 2011, and Azali Assoumani, originally president from 2002, returned to power for multiple terms, including after the 2018 constitutional referendum that extended presidential terms and the 2024 elections.

I mention this only because it shapes how I travel here. People are warm and curious, but I keep political conversation light and ask permission before photographing officials, mosques, or government buildings.

Tier-1 Destinations

Moroni and Grande Comore

I based myself in Moroni for four nights at the start. The capital sits on the western coast of Grande Comore (Ngazidja) with a population around 50,000, a working harbour where dhows still unload sacks of cloves, and a tight stone medina that climbs uphill from the seafront.

The Friday Mosque Ancienne, dated to 1457, is the oldest building I entered on the trip. Its minaret leans slightly, the prayer hall is open to non-Muslim visitors outside prayer times if you dress modestly, and the carved coral-stone doorways are a reminder that this was a Swahili-speaking trading port long before the French arrived. A few streets away, the newer Fakuni Friday Mosque takes Friday overflow and is easier to photograph from outside.

I walked the Médina early, before the heat, ducked into the Volo Volo Market for dried fish, fresh vanilla pods and bottles of distilled ylang-ylang oil, and then climbed to the Mausoleum of Said Ali, the last sultan of Grande Comore. The Korni Statue and the Said Mohamed Cheikh Stadium, completed in 2007, anchor the eastern edge of town. South of Moroni, I walked across La Coulée de Lave, the black basalt flow from the 1977 eruption of Mt Karthala that reached the sea and partly buried the village of Singani. Iconi, a short drive south, was once the sultan's capital and still has crumbling colonial relics and a clifftop bay associated with a 16th-century legend of women leaping to their deaths to escape Malagasy slavers.

Mount Karthala, the Largest Active Volcano Crater on Earth

Karthala is why most hikers come. At 2,361m it is the highest point in the Comoros, an active stratovolcano with a summit caldera roughly 3 km in diameter, the largest active volcanic crater in the world. The mountain last erupted on April 17, 2007, with earlier activity in May 2005 and in 1991, and it sits under near-constant monitoring.

I did it as a two-day strenuous hike from Nyumba Mvua, starting at dawn with a mandatory guide and a porter, sleeping in a basic shelter near the rim, and waking before sunrise to walk the crater edge. The trail moves through dense ferns, obsidian fields, and a fog forest that drips even on dry-season mornings, before opening onto a lunar landscape of grey ash and steaming vents. The summit crater is so wide that you can lose sight of the far rim when cloud rolls in. Le Trou du Prophète, a near-vertical drop into the inner pit, is the spot guides hold you back from. A Karthala National Park permit, required since 2010, costs around USD 25 and is arranged through your guide.

Anjouan: Mutsamudu, Domoni and Mt Ntringui

Anjouan (Nzwani), at 424 km², is the second-largest island and the one I found most beautiful. The capital Mutsamudu has around 30,000 residents, a working port, and the 17th-century Citadel completed in 1782 under Sultan Salim, with bastions overlooking the bay and a fresh-water cistern still functioning. Wandering the medina below the fort, I passed Swahili-style townhouses with carved doors, copper coffee pots cooling on stoops, and a daily fish market that runs on cash and shouting.

A two-hour shared taxi south brought me to Domoni, founded in the 11th century and the oldest town in the Comoros, once the original capital of the archipelago. The colonial mansions and the ruined Fortress de Bambao a short drive away give a strong sense of the sultanate-era trading economy. Inland, I hiked partway up Mt Ntringui at 1,595m, the highest point on Anjouan, through plantations of vanilla, cloves and ylang-ylang. Lake Dziani Boundouni, a roughly 200m-wide crater lake near the southern coast, is a quick stop with a sulphurous smell and dense surrounding ferns. For beach time, Adda Daoueni and Pomoni on the southwest shore have grey volcanic sand, calm water, and zero developed resorts.

Mohéli and the Mwali Marine Park

Mohéli (Mwali) is the smallest inhabited Comoros island at 211 km² and the one I'd return to first. Its Marine Park, formally the Mwali Marine Park, became a UNESCO Biosphere Reserve in 2003 and protects roughly 404 km² of coastline, reef and forest, including the Mohéli Beach Coastal Park section. I saw spinner dolphins on a one-hour boat ride from Nioumachoua, watched green sea turtles nest after dark on Itsamia Beach (the main nesting season runs July to September), and was told humpback whales pass through between July and September every year. Reef checks count 27 species of hard coral inside the protected zone.

Fomboni, the island's capital, is a sleepy seafront town. Lake Boundouni, a 1.7 km² crater lake inland, makes a quiet half-day with birdlife and grazing zebu. The eight beaches around Nioumachoua, scattered between offshore islets, are the easiest snorkel base. A 2009 reintroduction project has brought Aldabra giant tortoises back to a fenced section of forest, where I watched them feed at dusk.

This is also the place to ask about the coelacanth (Latimeria chalumnae). The species, alive when caught off South Africa in 1938 and confirmed in Comorian waters in 1952, has its main living population in deep volcanic caves between 150 and 250 metres down off these coasts. Locals occasionally land one as bycatch. Each fish grows over a metre long, is genuinely a living link to lobe-finned ancestors 400 million years back in the fossil record, and is now strictly protected.

Mayotte: A French Overseas Department in the Same Lagoon

Mayotte, the fourth island in the same geographic archipelago, became a French overseas department in 2011 and remains administratively part of France, with the euro as its currency. I add a short, balanced note on it because many Comoros travellers wonder about combining a visit. Politically, the Union of the Comoros and France hold different positions on Mayotte's status; I keep my own views out of conversation when I travel and stick to facts on the ground.

Mayotte has 374 km² of land split between Petite-Terre and Grande-Terre, a population around 290,000, and one of the largest lagoons in the world at roughly 1,500 km² (commonly cited as the second-largest enclosed lagoon globally). Mt Choungui rises to 594m on Grande-Terre, with a clear summit hike to a sharp peak, and the town of Sada offers a calmer alternative to the larger capital Mamoudzou. On Petite-Terre, Lac Dziani Dzaha is a striking green volcanic crater lake worth the short walk. Practical note: a Schengen-style French visa is generally required, separate from the Comorian visa-on-arrival.

Tier-2 Destinations

These spots filled my quieter days.

Iconi (Grande Comore): cliffside former sultan's capital with a tragic 16th-century history and clean coastal views south of Moroni.
Lake Hantsongoma (Anjouan): small inland crater lake reached on foot, surrounded by clove plantations.
Galawa Beach / Itsandra (Grande Comore): long white-sand beach north of Moroni, beside the abandoned Galawa resort, with reliable snorkelling off the headland.
Hahaya International Airport (HAH): the main entry point, around 20 minutes by taxi from Moroni, useful to know if your inter-island flight changes.
Lac Salé (Grande Comore): a small, briny crater lake near Mitsamiouli on the north coast, easy to combine with Galawa Beach.

Sample Costs in KMF, USD, EUR and INR

I paid in a mix of Comorian francs and US dollars. Rough rates while I was there: KMF 460 = USD 1, EUR 1 = KMF 492, USD 1 = INR 84. US dollars are widely accepted across hotels and dive shops, euros at fewer outlets, and Indian rupees nowhere.

Langouste lobster plate / chicken Comorian curry	3,700-6,900	8-15	672-1,260
Fresh vanilla pods, 50g	1,500-3,000	3-7	252-588
Inter-island ferry (Karama Express, Lemardja)	27,600-55,200	60-120	5,040-10,080
Inter-island small plane (AB Aviation)	46,000-92,000	100-200	8,400-16,800

ATMs are practically Moroni-only. I carried crisp post-2009 USD notes in small denominations for everywhere else.

Planning Notes

Visa and entry: Visa-on-arrival at Hahaya costs USD 30 for 30 days for most nationalities. I showed a return ticket and a printed hotel booking. Indian passport holders find the process equally straightforward as long as both items are ready.

When to go: I travelled in the dry, cooler season between May and November, with daytime temperatures between 22 and 28 degrees Celsius. The wet season from December to April brings cyclones, oppressive humidity, and frequent boat cancellations, so I'd avoid it unless you must.

Getting there: Hahaya International (HAH) on Grande Comore is the main hub. I flew in on Kenya Airways from Nairobi. Air Madagascar, Air Tanzania, and seasonal Ethiopian Airlines services also connect, with the Air Tanzania flight from Dar es Salaam clocking around 50 minutes.

Getting around: Inside each island, shared taxi-brousse minibuses (commonly called Tata Tata or Sotcom routes) cover almost every village for a few hundred KMF. Between islands I used a mix of Sotcom and other inter-island ferries (Karama Express, Lemardja) and short hops on AB Aviation, the small-aircraft carrier, at USD 100-200 a leg. Roads outside Moroni are rough; a 4WD or a hired taxi is realistic for full days.

Food: My favourite local dishes were mtsolola (saffron-spiced rice with breadfruit and coconut), grilled langouste straight off the reef, Comorian-style chicken curry with coconut milk, and ripe breadfruit roasted over coals. Ylang-ylang flowers occasionally garnish festive plates. Alcohol is prohibited in public under the country's Sunni Muslim norms, though some hotel restaurants serve beer and wine to non-Muslim guests. Green tea with cloves and cardamom is the constant.

Languages: Locals switch freely between French (administration), Arabic (religion and signage), and Comorian Shimasiwa, a Bantu language with strong Swahili and Arabic loanwords. A handful of French phrases will carry you almost everywhere on Grande Comore and Anjouan.

FAQs

Do I need a visa in advance? No. Visa-on-arrival costs USD 30 for 30 days for most nationalities, with onward travel proof and accommodation confirmation.

When should I visit? May to November is dry, cooler and stable. December to April is wet, humid and cyclone-prone.

Is Mt Karthala safe to hike? Yes, on the standard two-day route from Nyumba Mvua with a licensed guide. Altitude (2,361m), fog, and obsidian-strewn paths make a guide mandatory, and you'll need a Karthala National Park permit.

How do I travel between islands? Ferries (Karama Express and similar) cost USD 60-120 but can be rough and weather-dependent. AB Aviation small-plane hops at USD 100-200 are safer in poor weather, particularly to Mohéli.

Is alcohol available? Comoros is roughly 99% Sunni Muslim and alcohol is prohibited in public spaces. Some hotel restaurants serve it to non-Muslim guests, but I treat it as an exception.

Can I drink the tap water? No. I stuck strictly to bottled or filtered water, including for brushing teeth.

What plug type does Comoros use? Type C and Type E sockets at 220V, the same as France, so European adaptors work.

Is tipping expected? Tips are appreciated but not mandatory. I left around 10% in tourist-facing restaurants and rounded up taxis.

Local Phrases I Used Daily

Mixing French, Arabic and Shimasiwa got me through almost every interaction.

Bonjour - hello (French, universal)
Salaam alaikum / Wa alaikum salaam - peace upon you / and upon you (Arabic greeting)
Jeje jeje - informal hello, hello (Shimasiwa)
Marahaba - thank you (Shimasiwa, from Arabic)
Merci beaucoup - thank you very much (French)
Lakini - but (Shimasiwa, loan from Swahili)
Ndio / La - yes / no
Insha'Allah - if God wills (Arabic, used constantly)
Halisi - really, truly (Shimasiwa)
Ngapi? - how much? (Shimasiwa)
C'est combien? - how much is it? (French)
Où est...? - where is...? (French)
Karibu - welcome (Shimasiwa/Swahili)
Pole pole - slowly slowly (Swahili-style, widely understood)
Tafadhali - please (Arabic-rooted, used in Shimasiwa)
Kwaheri - goodbye (Shimasiwa)

Cultural Notes

Sunni Islam shapes daily life for around 99% of the population. The five daily prayers organise the rhythm of work, the call from the Friday Mosque Ancienne marks midday on Fridays in Moroni, and Ramadan is observed strictly. I avoided eating, drinking and smoking in public during daylight hours of Ramadan when I returned for a short second trip.

Modest dress is expected, especially for women. I saw most local women cover their hair and wear long, loose layers in town; for visiting women, a light scarf and trousers or a long skirt are appropriate. Men should wear long trousers in towns and at mosques, and shoulders covered out of respect.

The Grand Mariage, or Anda, is the most striking cultural institution I encountered. This seven-day traditional wedding ritual confirms a man's social status within his clan, and historically was effectively required before holding political or community office. The ceremonies, music, gold jewellery, feasts, and gift exchange involve the whole village. If you are invited, accept, dress well, and bring a small respectful gift.

Comorian women often wear a yellow-white face mask called msindzano, ground from sandalwood and ylang-ylang paste, both as sun protection and as a marker of cultural identity. Music includes taarab (Swahili-influenced sung poetry), ngoma drumming, and occasional cabaret-style performances in family halls.

The Comoros, along with parts of Madagascar and Réunion, produce roughly 80% of the world's ylang-ylang oil supply, much of it bought by French perfume houses; the flower is famously a component of Chanel No 5. Vanilla and cloves are the other two pillars of the export economy, which is why these are called the Perfume Islands.

I keep two topics off the table in casual conversation: alcohol and the country's long history of coup attempts. Locals will discuss both if they raise them; I let them lead.

Pre-Trip Prep

Visa-on-arrival USD 30, 30 days; carry printed onward ticket and accommodation booking.
Plug Type C and Type E, 220V; standard European adaptors work.
Modest clothing for towns and mosques, plus zinc-based reef-safe sunscreen for snorkelling inside the Mwali Marine Park.
Strong DEET-based insect repellent and a discussion with a travel doctor about malaria prophylaxis; the country is malarial in lowland areas.
Yellow fever certificate if arriving from or transiting an endemic country.
Crisp post-2009 USD notes in small denominations for inter-island travel; ATMs are concentrated in Moroni and unreliable elsewhere.
Offline maps and translated phrases on your phone; data coverage is spotty outside the capitals.
