Karthala National Park

When to go

Drier days are usually chosen for the ascent, but clouds, rain and wind on Karthala change rapidly. Tropical cyclones can affect the Comoros from January to May. Current volcano reports, weather, trail conditions and the park permit must be checked before setting off.

Things to see and do

When the trail is open and with a local guide, you can climb through moist mountain forests and old lava fields to the large caldera, observe endemic birds and learn about the volcanic landscape. The route is long and physically demanding. Do not approach fumaroles, fissures or unstable crater edges.

Practical tips

An experienced guide, early start, water, food, rain protection, a warm layer, a torch, first aid and sturdy shoes are required. Mobile coverage and rescue infrastructure are limited, and medical facilities in the Comoros are basic. Leave details of your route and abandon the trip during a volcano warning or bad weather.

Getting there and getting around

The usual starting point is Moroni; from there, travel along an agreed route to a village or trailhead, then continue on foot. Many minor roads are in poor condition. Transfers, a guide, permission and the return journey must be confirmed in advance, not on the day of the hike.

Where to stay

The most convenient base is Moroni or a confirmed guesthouse in a village along the chosen route. Check electricity, water, mosquito nets, early breakfast and luggage storage. An overnight stay at the crater is an option only as part of an authorised programme with a guide and full equipment.

What to try

Rice, cassava, plantains, fish, coconut sauces, spices, vanilla and dishes with cloves are common on Ngazidja. Take sufficient high-energy food and safe water for the hike; there are no supplies along the way. Respect local Islamic rules, especially during Ramadan.
