Mount Kenya straddles Meru County, Nyeri County and the northern most portion of Kirinyaga County.

It has been located as Meru County due to the National Park being largely in Meru County.

Mount Kenya, which reaches a summit of 5200 m, is a central volcano located to the east of the East African Rift. The main eruptive phase of the Mount Kenya volcanics is of Pliocene to Pleistocene age (Baker et al., 1971; Rock, 1976; Price et al., 1985) and overlies tufts and basalts of Miocene-Pliocene age which rest on a Precambrian basement of gneisses and schists (Baker, 1967). The main eruptive phase is composed of basalts, phonolites, kenytes and trachytes with the summit consisting of a complex intrusive plug of syenite and phonolite. The most recent activity on Mount Kenya occurred as satellite eruptions which built pyroclastic cones and extrusive domes of basalt and trachyte. These later eruptives, which were also extensively emplaced as dykes are believed to be of Pleistocene age. Erosion of the summit by glaciers which are still active has extensively exposed the central core of the volcano.
