Overview
Comoros is an archipelago nation in the Indian Ocean, situated between the northern tip of Madagascar and the coast of Mozambique. It comprises three main islands under national sovereignty — Grande Comore (Ngazidja), Anjouan (Ndzuwani), and Mohéli (Mwali) — plus the island of Mayotte, which is administered by France and has a separate political status.
The islands are volcanic in origin. Mount Karthala on Grande Comore is one of the world's largest active shield volcanoes and continues to erupt periodically. The landscape shifts quickly from black lava fields near the coast to dense montane forest higher up, giving the islands a raw, dramatic character that rewards visitors willing to get off the main tracks.
Comoros is among the world's least-visited countries, not because of danger or unwelcoming locals, but largely due to limited air connections and modest tourism infrastructure. Travelers who do come tend to be divers, naturalists, or people specifically seeking somewhere genuinely off the beaten path. The flip side is that the reefs, forests, and fishing villages feel largely undiscovered.
The country has a deeply Islamic culture shaped by Arab, African, and French colonial influences. This blend is visible in architecture, cuisine, music, and daily social life. Visitors who approach with curiosity and respect typically find Comorians warm and hospitable.
Before You Go
Visas
Comoros has historically offered visas on arrival to many nationalities, but entry requirements can change. Do not rely on any single source. Check TravelerPulse's Visas section for the latest guidance and verify directly with the official Comorian immigration authority or your nearest Comorian embassy before travel.
Health
Yellow fever vaccination is required if you are arriving from a yellow fever-endemic country; carry your vaccination certificate. Malaria is present on all three main islands — consult a travel medicine specialist about prophylaxis well before departure. Ensure routine vaccinations are up to date. Medical facilities on the islands are basic; travelers with complex health needs should carry supplies and consider medical evacuation insurance.
Travel Insurance
Medical evacuation from Comoros is expensive and logistically complicated. Comprehensive travel insurance with emergency evacuation cover is strongly recommended.
What to Pack
- Reef-safe sunscreen (coral ecosystems are fragile)
- Personal medications and a basic first-aid kit
- Lightweight modest clothing (observe Islamic dress norms, especially outside resorts)
- Offline maps or downloaded content; connectivity can be unreliable
- Cash in small denominations; card acceptance is limited outside Moroni
Getting There
By Air
Prince Said Ibrahim International Airport in Moroni (IATA: HAH) on Grande Comore is the main international gateway. A smaller airport at Ouani serves Anjouan. Air connections are limited and typically route through regional hubs such as Nairobi, Addis Ababa, Dar es Salaam, Antananarivo, and Réunion. Check current routes and schedules with airlines directly, as services change frequently and seats can be scarce during peak periods.
There are no direct scheduled flights from Europe or North America at the time of writing; most travelers connect through East African hubs. Build generous layover times into your itinerary and be prepared for schedule disruptions.
By Sea
Ferry and cargo boat services connect Comoros with Mayotte and, less regularly, Madagascar and the East African coast. These services are slow and schedules are irregular — verify locally before planning around them. The channel crossings between the main islands are served by smaller inter-island ferries (see Getting Around).
Getting Around
Between Islands
Domestic flights link Moroni (Grande Comore), Anjouan, and Mohéli via small aircraft; book well in advance as capacity is very limited. Inter-island ferries also operate but can be slow, and sea conditions between islands can be rough, especially outside the dry season. Verify schedules locally on arrival.
On the Islands
Shared taxis (taxi-brousse) are the primary form of public transport on Grande Comore and Anjouan. They are inexpensive and cover most routes, though they depart when full rather than on fixed schedules. Private taxis are available in Moroni for more predictable travel. On Mohéli, the road network is limited and vehicles fewer; hiring a local guide with transport is often the practical approach.
Driving
Roads vary considerably in quality. Four-wheel-drive vehicles are advisable for interior or mountain routes. Car hire is available in Moroni — verify current operators locally. An international driving permit is advisable alongside your national license.
In Moroni
Moroni, the capital, is compact enough to walk in the central medina area. Tuk-tuks and motos (motorcycle taxis) provide short-hop transport around town.
Things to See & Do
Mount Karthala
Hiking to the caldera of Karthala (2,361 m) is the signature overland experience on Grande Comore. The ascent typically takes one to two days and requires a guide; the volcano is active, so check current activity status before attempting the climb. The montane forest on the flanks is rich in endemic bird species.
Diving and Snorkeling
Comoros sits within the Western Indian Ocean's biodiversity belt. Reefs around all three islands offer encounters with hawksbill and green turtles, reef sharks, rays, and abundant reef fish. Mohéli Marine Park, Comoros' only officially protected marine area, is widely considered to offer the best-preserved underwater environment. Dive operators exist but are few; confirm equipment standards and guide qualifications before booking.
Mohéli (Mwali)
The smallest and least developed of the main islands is favored by travelers seeking untouched forest, quiet beaches, and nesting sea turtles (primarily between November and February, though the nesting season overlaps with cyclone season — plan carefully). Community-based tourism initiatives on Mohéli offer homestay-style accommodation and guided experiences.
Anjouan (Ndzuwani)
Anjouan is the most topographically dramatic island, with steep mountains, crater lakes (including Lac Dzialandze), and waterfalls reachable on foot. The island also has significant ylang-ylang and clove cultivation; visiting a distillery or plantation provides insight into the agricultural economy that shapes Comorian daily life.
Medina of Moroni
Moroni's old town clusters around the Friday Mosque (Mosquée du Vendredi) near the seafront. The narrow lanes, Arab-influenced architecture, and busy market make for absorbing wandering. Non-Muslims should be respectful around mosque precincts and mindful of prayer times.
Food & Drink
Comorian cuisine blends East African, Arab, and French influences. Rice is the central staple and appears at almost every meal, typically accompanied by fish, meat, or vegetable stews heavily seasoned with coconut milk, turmeric, cardamom, cloves, and cinnamon. Langouste (spiny lobster) and fresh fish are widely available near the coast.
Dishes to look for:
- Mkatra foutra — a coconut milk flatbread often eaten at breakfast
- Romazava — a broth-based stew, a regional variation on a dish found across the Indian Ocean islands
- Pilaou — spiced rice with meat, reflecting Arab culinary heritage
- Fresh grilled fish at coastal markets
Comoros is a predominantly Muslim country; alcohol is not widely available and is absent from most local restaurants and guesthouses. Some hotels catering to international visitors may serve alcohol — verify before you go if this matters to your plans. Locally produced fruit juices, coconut water, and strong black coffee or spiced tea are the common daily drinks.
Food safety standards vary; drink bottled or treated water, and be cautious with street food prepared under unclear hygiene conditions, particularly outside the main towns.
Practical Information
Money
The Comorian Franc (KMF) is the national currency. ATMs exist in Moroni but are unreliable in terms of uptime and may not accept all foreign cards. Carry sufficient euros or US dollars as a backup — euros are generally easier to exchange. Card payment is uncommon outside a small number of hotels and larger establishments in Moroni. Negotiate prices for taxis and markets in advance.
Connectivity
Mobile data is available via local SIM cards, which can be purchased in Moroni. Coverage is reasonable in main towns but drops significantly in rural and highland areas. Wi-Fi is available in some hotels; speeds are generally slow by international standards.
Electricity
The standard voltage is 220V. Plug types used include European two-pin round plugs (Type C/E). Power outages occur regularly; check whether your accommodation has backup power if this is important.
Emergency Contacts
The country phone prefix is +269. For emergency services, ask your hotel or accommodation host for locally current emergency numbers on arrival, as centralized emergency numbers are not uniformly reliable across all islands. Travel insurance emergency lines are your most dependable resource for medical evacuations.
Safety
Comoros is generally peaceful and violent crime against tourists is uncommon. Petty theft, particularly in crowded market areas, is the most realistic risk. Normal urban precautions apply: keep valuables secure, avoid displaying expensive electronics, and be aware of your surroundings.
Check your home government's current travel advisory before departure — political situations in the country have been periodically unstable historically, and advisories can shift. The situation is generally calm but it is worth staying informed.
Volcanic activity on Grande Comore is an ongoing consideration. Mount Karthala has erupted multiple times in recent decades. Monitor local and international geological monitoring sources if you plan to hike the volcano, and follow guidance from local authorities.
At sea, inter-island boat crossings can be rough and vessels are not always well maintained by international safety standards. Exercise your own judgment about seaworthiness before boarding ferries, particularly in poor weather.
Local Culture & Etiquette
Islam is central to daily life in Comoros; the large majority of the population is Sunni Muslim. The call to prayer marks the rhythm of each day, and Friday is observed as the main day of communal prayer. Visitors should dress modestly — covering shoulders and knees is appropriate throughout the islands, and this is particularly important when entering towns, markets, or anywhere near a mosque.
During Ramadan, eating, drinking, and smoking in public during daylight hours is considered disrespectful. Some restaurants and food stalls may be closed during the day; adjust your expectations and schedule accordingly.
Greetings matter. Taking a moment to exchange pleasantries before getting to the point of a transaction or question is valued culturally. Learning even a few words of Shikomori — the national Comorian language — is received warmly.
Photography: Ask permission before photographing people, especially women. Photographing government buildings, military installations, or police should be avoided. Overall, a respectful and curious approach to interaction will be reciprocated in kind.
