The Oloolua nature trail meanders through thick forest vines and undergrowth below giant indigenous trees and bushes, in some places following the course of the Mbagathi River that cuts through the forest. Giant riverside bamboo stands beckon you to descend some rickety stairs to the river and rest on benches built under the bamboo. Trickling water and chirping birds, the only sounds you hear as you rest, cause you into a reflective mood.
Along the trail close to the river, you encounter a 33m long cave. Reputed to have once been home to Mau Mau freedom fighters during the colonial period of Kenya’s History. A thick pile of guano underfoot and the occasional disturbance of bats flitting past you bring to your attention the existence of a bat colony within.
A papyrus swamp further down the river offers a further glimpse into the rich biodiversity of this indigenous Forest.
