Top Hiking Trails
The best hikes Comoros has to offer.
Mount Karthala Summit Trek
challengingThe 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.
Mount Karthala Day Hike (Boboni to Shelter)
moderateA shorter version of the Karthala trek for those unable to commit to an overnight trip. The trail from Boboni village climbs through cloud forest to the stone mountain shelter, offering spectacular views and diverse vegetation without requiring summit camping gear.
Mohéli Marine Park Coastal Trail
easyA 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
easyA 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.
Ntringui Forest Trek, Anjouan
moderateThe Ntringui massif at the heart of Anjouan preserves one of Comoros' last remaining primary forests, home to the endangered Livingstone's fruit bat and Anjouan scops owl. The hike climbs through clove and ylang-ylang plantations before entering ancient cloud forest.
Dziani Boundouni Crater Lake Walk, Mohéli
easyThe 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.
Bangoi Kouni Lava Tube Trail
easyA fascinating geological walk through a network of ancient lava tubes near Chomoni Beach. The tubes were formed during Mount Karthala's historic eruptions and stretch for several kilometers. Local guides from Chomoni village are required and cost around $15 for the tour.
Trails by Difficulty
Find trails that match your fitness level.
🟢 Easy
Flat or gently rolling terrain suitable for most fitness levels. Lac Salé loop, coastal Mohéli trail, and Dziani Boundouni walks fall in this category. Sandals or trainers sufficient in dry season.
🟡 Moderate
Significant elevation gain requiring reasonable fitness. Karthala day hike (to shelter) and Ntringui Trek require hiking boots and 4-6 hours commitment. Bring at least 2 liters of water per person.
🟠 Challenging
Demanding multi-hour ascents with substantial elevation gain. Mount Karthala summit requires good physical condition, appropriate gear, and a certified local guide. Not suitable for children under 12.
🔴 Expert
No technical mountaineering required in Comoros, but the full Karthala summit in poor weather or rainy season approaches expert-level difficulty with slippery lava fields and zero visibility. Guide essential in all conditions.

Hiking Safety
Stay safe on the trails.
Always tell someone your hiking plans and expected return time. Carry emergency communication device in remote areas.
Check weather conditions before setting out. Turn back if conditions deteriorate. Never underestimate mountains.
Stay on marked trails. Getting lost in unfamiliar terrain can be dangerous. Carry navigation tools.
Be aware of wildlife. Research local animals and know how to respond to encounters.
Start early to allow plenty of daylight. Always aim to be back before dark.
Local Hazards
- Active volcanic activity — Mount Karthala has erupted as recently as 2006; always check with local guides about current volcanic status before trekking
- Intense tropical sun above the forest line — wear a hat and high-SPF sunscreen and start early
- Dehydration — carry at least 2 liters of water per person; no reliable water sources on most mountain trails
- Slippery lava rock — volcanic surfaces become dangerously slick in wet conditions; proper footwear essential
- Mosquitoes — malaria is present; use DEET repellent and cover arms and legs in forest environments, especially dawn and dusk
- No mobile coverage on most trails — inform your accommodation of your planned route and estimated return time
- Sudden mist and cloud at higher elevations — visibility can drop to near zero quickly; guide knowledge of terrain is essential
Best Time to Hike
Plan your hiking adventure for optimal conditions.
🌸 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.
