A 3,100-metre extinct volcano twenty kilometres north of Debre Zeit, with twin summits visible from most of the lake area. The mountain dominates the skyline and gives the Bishoftu craters their distinctive backdrop.
A rough track climbs to the saddle from the south side; the rest is a steady walk through patches of remnant forest and grassland. Allow most of a day from the trailhead. The views from the top take in the whole lake cluster and, on a clear morning, a long stretch of the Rift Valley wall to the south.
