The name Karisimbi comes from the word 'amasimbi' in the local language, Kinyarwanda, which means snow. Snow can mostly be found during the dry season in June, July and August on the top of the volcano.

Between Karisimbi and Bisoke is the Karisoke Research Center, which was founded by Dian Fossey in order to observe the mountain gorillas living in this area.

On February 27, 1908, an expedition led by Egon Von Kirschstein was coming down the Branca Crater when a hailstorm and snowstorm caused twenty of the expedition's porters to perish.^[2][3]

In May 2010, a series of non-volcanic mudflows triggered by rain occurred along the volcano's western flank. The mudflows carried volcanic rocks and vegetation debris downhill. At Kibiriga, the mudflows caused severe damage and killed at least 50 people.^[4]
