Mount Gahinga, is a dormant/extinct volcano in the Virunga Mountains on the border between Rwanda and Uganda. Gahinga lies between Muhabura and Sabyinyo, but is the smallest of these three. Mount Gahinga, also known in the local Kinyarwanda/Rufumbira dialect as "a small pile of stones", has a swampy caldera on its peak. The caldera is believed to be about 180 meters wide. Mgahinga Gorilla National Park also got its name from this volcano.
