Mount Longonot is the neighboring volcano to the north of Mount Suswa, it is a massive stratovolcano with at least two calderas.  The ancestral volcano went caldera via an explosive series of eruptions, creating a 8 x 12 km caldera.  More recent volcanic activity built a stratovolcano in the caldera which is topped with a 1.8 km crater (caldera).

 It is heavily forested and has the standard compliment of Great Rift Valley wildlife, buffalo, eland, lion, leopard, bushbuck, zebra, giraffe and gazelles.  Recreation in the park includes biking, hiking, rock climbing, walking, game viewing, camping, and a large number of birds of prey.
