The Sabyinyo group frequently inhabits the closest territory to the park's edge, between Mount Sabyinyo, from which the group takes its name, and Mount Gahinga. They can usually be reached within a two-hour walk. The group is led by Guhonda, the largest silverback measured to date, at 220kg.
The Amahoro, meaning Peaceful, is lead by Ubumwe, who lives up to his name. There is a steep climb to reach the tranquil Amahoro group, however the climb is well worth it once in contact with this tranquil group.
Umubano Group lead by Charles the Silverback who took part of the Amahoro group to create its own when he matured into the same rank as Ubumwe. The two Silverbacks have met since, but Ubumwe seems to respect Charles and the two groups live peacefully alongside. Indeed, Umubano means "Live Together."
The Susa group is currently the largest group of gorillas in the world and the one originally studied by Dr. Dian Fossey.

The Kwitonda group includes three Silverbacks. This group came across to Rwanda from Uganda and the DRC to establish itself on the slopes of Mount Muhabura.
The Agashya group was named after it's commanding Silverback, who's name means "the News".

Agashya group is known to spend most of its time on the forested saddle between Mount Sabyinyo and Mount Gahinga.
The Hirwa group is an emerging group of members from the other groups. It is the newest group, residing mainly on the foothills of Mount Sabyinyo on the Gahinga side. It's name means "Lucky one".
