The most exciting activities Comoros has to offer.

1
Mount Karthala Summit Trek
Climb to the rim of one of the world's largest active volcanic craters, rising 2,361 meters above the Indian Ocean. The two-day guided ascent through montane cloud forest to alien lava fields and steaming fumaroles is the premier adventure activity in Comoros — demanding but deeply rewarding.
Best season: May to October (dry season)

2
Scuba Diving in Mohéli Marine Park
Dive the pristine coral walls and reef gardens of Mohéli Marine Park, one of the least-dived but most biodiverse marine protected areas in the Indian Ocean. Sites include volcanic drop-offs hosting giant trevally and barracuda, turtle cleaning stations, and deepwater walls near coelacanth habitat zones.
Best season: April to November (calmest seas)
-
3
Humpback Whale Watching
Between July and October, humpback whales migrate to the Mozambique Channel waters of Comoros to give birth and nurse their calves. Boat trips from Mohéli and occasionally Moroni offer extraordinary encounters with breaching adults and playful calves in some of their most important breeding grounds in the Indian Ocean.
Best season: July to October (peak August-September)
-
4
Sea Turtle Snorkeling, Mohéli
Snorkel alongside green sea turtles in the warm shallows of Mohéli Marine Park, home to one of the Western Indian Ocean's healthiest turtle populations. Evening guided walks on Nioumachoua Beach allow observation of nesting females without disturbing them, in one of the region's most important rookeries.
Best season: Year-round (turtle nesting peak November-March)

Bangoi Kouni Lava Tube Caving
Explore a network of ancient lava tubes formed by Mount Karthala's historic eruptions near Chomoni Beach.

Headlamps provided; no technical equipment needed.
Best season: May to October (dry season)

Ntringui Forest Trek, Anjouan
Trek through Anjouan's ancient cloud forest to the summit of Mount Ntringui, home to the world's largest colony of Livingstone's fruit bats and the endangered Anjouan scops owl. The hike passes through working ylang-ylang and clove plantations before entering primary forest that feels genuinely remote and wild.
Best season: May to October
-
7
Traditional Pirogue Sailing
Sail the Indian Ocean in a traditional Comorian outrigger pirogue with local fishermen from Chomoni or Mitsamiouli Beach. Learn the fishing techniques and navigational knowledge passed down through generations, and enjoy snorkeling stops at offshore reef patches that only the fishermen know about.

Island-Hopping by Light Aircraft
Take domestic flights on small 18-seater aircraft between Grande Comore, Anjouan, and Mohéli, experiencing the thrill of low-altitude flight over volcanic peaks, coral reefs, and impossibly blue ocean.
