A steep day hike to a crater lake on a Virunga volcano straddling Rwanda and the DR Congo
Bisoke is the Virunga volcano that many visitors to Volcanoes National Park choose to climb. It stands on the border between Rwanda and the Democratic Republic of the Congo, with its summit on the Rwandan side, and its crater holds a lake that Visit Rwanda places at about 3,700 m. On a clear day the view takes in neighbouring volcanoes and the forests below.
The climb is steep and often muddy, rising through bamboo and Hagenia forest into open moorland of giant lobelias and groundsels, but it is walkable for fit hikers and can be done in a day. Clouds frequently cover the top, which adds to the atmosphere but means the lake may appear only briefly through the mist.
Bisoke is a stratovolcano on the Albertine branch of the East African Rift. Its recorded eruptions include one in 1891 and another in August 1957, when activity about 11 km north of the summit created two small cones on its northern flank; the area is still considered geologically active.
The mountain is closely linked with gorilla research. Dian Fossey founded the Karisoke Research Centre in 1967 in the saddle between Karisimbi and Bisoke, and the name Karisoke combines the two. Gorillas still range on Bisoke's slopes.
The farming communities at the foot of Bisoke grow potatoes, beans and pyrethrum on fertile volcanic soils, and many porters on the hike come from these villages. The mountain's forests are also a reminder of the long effort, involving rangers, trackers and researchers from the area, to protect the gorillas that live on its slopes.
The hike requires a permit and an armed park guide, and Visit Rwanda notes it can take anything from five hours to a whole day. Expect a steep, often slippery path with sections where you may use your hands. Porters can be hired to carry daypacks, and walking poles are helpful on the descent.
For a gentler alternative, the hike to Lake Ngezi at the foot of Bisoke takes about three hours in total. More ambitious walkers can tackle Karisimbi, which takes two days with a night camping on the mountain.
The dry seasons from June to September and December to February give the best chance of firm trails and a clear view into the crater. In the rainy months of March to May and October to November the path becomes very muddy and the summit is usually in cloud. Temperatures near the top can be cold at any time of year.

Hikes in Volcanoes National Park are organised from the park headquarters at Kinigi, where lodges and guesthouses are located. Musanze town, about 13 km from Kinigi, has restaurants, banks and markets and a wider choice of accommodation. Transport to the trailhead is usually by private 4x4 vehicle arranged with a driver or tour operator.
