The Koromosho Falls, some 25 kilometres to the west of Eldoret, is where the River Sosiani plunges 70 metres from the flat fertile plateau over a granite escarpment. It is only the sound of the water that betrays the falls, hidden in a mass of rocks and trees. From the high rocks downstream, one can see a big cave behind the falling waters where residents say some animals live. The winding V-shaped valley cut by the Sosiani adds to the beauty of the scene. From the river bed, the valley rises on both sides some 120 metres and ends only 50 kilometres downstream after Ndalat Hills near Kapkaren.
