Mount Karisimbi is one of the eight volcanoes that make up the Virunga Mountain Range, home to the endangered mountain gorillas. These volcanoes are shared between Volcanoes National Park in Rwanda, Virunga National Park in the Democratic Republic of Congo, and Mgahinga Gorilla National Park in Uganda. Two of the Virunga volcanoes: Mount Nyamuragira and Mount Nyiragongo, are still active and are both found in Congo.
Mount Karisimbi
Mount Karisimbi is the highest volcano in the Virunga range, standing at 4,507 meters above sea level. It is also the sixth-highest mountain in Africa. This stratovolcano is currently dormant and lies on the border between Rwanda and the Democratic Republic of Congo, within Volcanoes National Park.
The name Karisimbi comes from the local word amasimbi, meaning “white shell,” because the mountain’s peak is often covered with snow for most of the year. Studies show that Mount Karisimbi’s lava is between 0.24 and 0.010 million years old, meaning it is a relatively young volcano.
Mount Karisimbi is also close to the Karisoke Research Center, which was founded by Dian Fossey. The name “Karisoke” was formed by combining Karisimbi and Bisoke, two neighboring volcanoes. The mountain’s lava thickness ranges from 40 to 60 meters, with some parts reaching over 140 meters, and its lava flows extend up to 12 kilometers, covering an area of about 24 square kilometers.
The mountain is famous for its unique vegetation, which changes with altitude. It has four vegetation zones, from dense forests at the base to a barren volcanic summit. The snow at the top of Mount Karisimbi is caused by sleet and hail, which result from the cold high-altitude climate and frequent storms.
Hiking Mount Karisimbi
The Mount Karisimbi hike starts early in the morning and takes two days to complete. The trail passes through the slopes of Mount Bisoke before reaching the first camp at 3,700 meters, where hikers spend the night. The next morning, the climb continues to the summit.
At the top of Mount Karisimbi, hikers are rewarded with clear views of Mount Nyiragongo and the surrounding volcanoes. Along the trail, you may also spot birds, primates, and other wildlife that live in the forests.
Gorilla Trekking
Adding gorilla trekking to your Mount Karisimbi hike is an unforgettable experience. Mountain gorillas share 98% of their DNA with humans and can only be found in Uganda, Rwanda, and the Democratic Republic of Congo.
The gorilla trek starts early in the morning and can take several hours, depending on the location of the gorilla family. Once the group is found, visitors spend one hour observing and photographing them in their natural habitat.
What to Bring
Temperatures on Mount Karisimbi can drop to zero degrees, especially at night and in the early morning. For a comfortable and safe hike, make sure to bring:
- Strong hiking boots
- Warm clothing and jackets
- Garden gloves
- Plenty of drinking water
- Energy snacks
- Rain gear
Best Time to Visit
Mount Karisimbi can be visited all year round, but the best time for hiking is during the dry seasons: from June to August and December to February. During these months, the trails are less muddy and slippery, and the skies are clear, making it perfect for photography and scenic views.
