Hiking to the top of Mt Karismbi is one of the key tourism activities you should not miss on your Rwanda safari to Volcanoes National Park. Rising at an elevation of about 4507m above sea level is MT. Karisimbi, a stratovolcano which is the highest of the eight major volcanoes of the Virunga field and the 5th highest in Africa. It strides along the border between Democratic Republic of Congo and Rwanda on the western branch of the African Rift valley. Karisimbi lavas have been dated from 0.24 Ma to 0.010 Ma indicating that the volcano is very young. The name Karisimbi is derived from the word ‘amasimbi’ in Kinyarwanda which means “white shell”, referring to the white-capped summit which is often seen on top of this volcano. It is flanked by Mikeno to the north, Bisoke to the east and Nyiragongo to the west, on the other side of the Rift Valley. The mountain is situated in Volcanoes national park, popularly known for the mountain gorillas.
