Mount Karthala Summit Trek
The ascent of Mount Karthala, one of the world's largest active volcanoes, is the most iconic hike in Comoros. The trail begins in the village of Boboni at around 600m and passes through lush montane forest alive with Livingstone's flying foxes before emerging into alien lava fields near the crater rim.

Mohéli Marine Park Coastal Trail
A coastal walking path between Nioumachoua and Miringoni on Mohéli's southern coast, passing through mangrove edges, fishing villages, and turtle nesting beaches. The chance of spotting green sea turtles in the shallows makes this one of Comoros' most rewarding easy walks.

Lac Salé Crater Loop
A short but scenic loop walk around Lac Salé, a mysterious saltwater crater lake surrounded by dense vegetation. The vivid blue-green water contrasting with the forested crater walls creates a surreal landscape. Easy enough for children and older visitors.

Dziani Boundouni Crater Lake Walk, Mohéli
The walk to Dziani Boundouni, Mohéli's emerald-green crater lake, is a short but rewarding excursion through dense vegetation. The lake's vivid color comes from algae and minerals, and flamingoes occasionally visit. Local guides from Fomboni are essential.

When to hike
Seasonal conditions in Comoros.
- Spring
- April is a shoulder month at the transition between seasons — the forest is lush and green from recent rains but trails may be slippery on Karthala. Good for low-elevation walks on Mohéli.
- Summer
- May to October (Comoros' dry season) is the prime hiking season. Karthala trails are drier and safer, visibility is best, and overnight stays on the mountain are feasible. Ntringui on Anjouan is best June-August.
- Fall
- November marks the beginning of the rainy season. Karthala becomes slippery and summit visibility poor. Low-elevation coastal and crater lake walks remain viable with waterproof gear.
- Winter
- December to March is the wet season — heavy rain and mist make the Karthala summit inadvisable and trails extremely muddy. Coastal walks and lava tube tours can continue in dry spells.
Local hazards
What to watch out for on the trail.
Hazard: Active volcanic activity — Mount Karthala has erupted as recently as 2006; always check with local guides about current volcanic status before trekking
Hazard: Intense tropical sun above the forest line — wear a hat and high-SPF sunscreen and start early
Hazard: Dehydration — carry at least 2 liters of water per person; no reliable water sources on most mountain trails
Hazard: Slippery lava rock — volcanic surfaces become dangerously slick in wet conditions; proper footwear essential
Hazard: Mosquitoes — malaria is present; use DEET repellent and cover arms and legs in forest environments, especially dawn and dusk
Hazard: No mobile coverage on most trails — inform your accommodation of your planned route and estimated return time
Hazard: Sudden mist and cloud at higher elevations — visibility can drop to near zero quickly; guide knowledge of terrain is essential
