This is the family that split from the Original Susa (Susa-A) family a few years ago and now it’s called Susa-B or Karisimbi Group. It lives in the Mt. Karisimbi area of Volcanoes National Park and is also suited to visits from more serious hikers. Both of these groups can potentially involve a full day’s trek. It contains 15 individuals and it always stays in the slopes of Karisimbi Volcano (4507M)–the highest pick of Rwanda. The Karisimbi Group is better suited to visits for more serious hikers. It appears that they have established their home range high up on the slopes of the Karisimbi caldera.
