Mousa Ali

Mousa Ali is a stratovolcano located at the tripoint where Eritrea, Ethiopia, and Djibouti meet, rising to 2,021 meters elevation. The mountain features two distinct peaks separated by a wide caldera that contains rhyolitic lava domes.

The mountain was officially designated as a tripoint marker by the Eritrea-Ethiopia Boundary Commission in 2002. This decision formalized its role as a natural border point between the three neighboring nations.

Afar communities inhabit the surrounding slopes and have built their lives around the volcanic landscape for centuries. These groups maintain strong connections to the land through pastoral practices adapted to the harsh terrain.

Temperatures on the mountain range from about 7 degrees Celsius in winter to around 26 degrees Celsius in summer, so proper planning is essential. Visitors should bring layers for changing conditions and account for the high elevation during any climb.

The mountain has two separate peaks of different elevations that create a striking geological formation. The deep caldera separating these summits reveals the volcanic history recorded in the rock layers and landscape.
