Things to Do in Comoros: Volcano, Beaches, Turtles and Old Towns

Things to do in Comoros depend on the island: a volcano and a capital on Grande Comore, historic medinas on Anjouan, a marine park and sea turtles on Moheli.

Things to do in Comoros: the three islands

Things to do in Comoros are organised island by island. Grande Comore has the Karthala volcano, Moroni and the northern landscapes. Anjouan has historic towns and a sacred lake. Moheli is built around nature, with a national park and turtle nesting beaches. There is no combined ticket or national sightseeing pass, so each place is visited separately.

Opening hours and fees for sights are not published reliably. Ask locally or at your accommodation, and check before entering a mosque, a village or a protected area.

Our take: things to do in the Comoros

For the volcano, pick the Karthala hike. For the landscapes and beaches of the north, the day trip from Moroni is enough. For Mutsamudu, Itsamia and the other islands, you need the 8-day route.

Grande Comore: volcano, capital and north

Where most trips begin.

Mount Karthala is an active volcano in the south of the island. The hike is long and depends on the operator and the group's fitness, so read the safety notes before choosing a date. In Moroni, the medina belongs to the towns inscribed as World Heritage in 2026, and the Friday mosque is listed among the heritage elements. An inscription gives no opening hours for houses or mosques, so ask residents for permission before going inside.

In the north, Lac Sale is a crater lake whose colour changes with the weather, and the Dragon's Back is a stretch of coastal hills near Ivoini. Do not treat Lac Sale as a place to swim. It is only a proposal for UNESCO listing, submitted on 19 March 2026. The beaches of Mitsamiouli and the Trou du Prophete are named by the tourism office, with no swimming guarantee. Everything is gathered on the Grande Comore page.

Anjouan: medinas, citadel and sacred lake

At Mutsamudu, the tourism office describes a medina overlooked by a citadel. Mutsamudu and Domoni are among the historic towns of the UNESCO site, yet no reliable opening hours or fees exist for the citadel. Lake Dzialandze, at 910 m near Mont Ntringui, is reached on foot. It is a sacred place and a water reserve, and swimming is prohibited. Do not confuse it with Lac Sale on Grande Comore.

The island also grows ylang-ylang, cloves and vanilla, which does not prove that a distillery can be visited every day. For more, see the Anjouan page.

Moheli: marine park and turtles

The smallest of the three islands and the most nature-focused.

Moheli National Park protects marine and land habitats. Keep the marine park, designated in 2001, apart from the biosphere reserve, recognised by UNESCO in 2020 over 66,286 hectares. At Itsamia, a local conservation group describes monitoring of green turtles, with nesting especially strong from April to June. That is not a sightings guarantee: visitor rules, distances and fees are not published in a usable form, so ask the park or the group. Details are on the Moheli page.

To compare beaches across the islands, read Comoros beaches. It gives place names, not a list of safe beaches. Spain warns of currents and high water on some beaches, and the United Kingdom advises covered clothing.
