At first light the ridge is a silhouette—sweeps of grass and the ragged teeth of radio masts carving the sky, the wind already busy at work, pushing you along the trail. You leave Nairobi’s smudge of traffic behind and, by the time the van drops you at the northern foot in Ngong, the city has shrunk to a glitter on the horizon. You step onto a path that climbs from 1,961 m and teases the lungs with a steady ascent before the trail unfurls into a series of rolling summits; the highest peak in the range tops out around 2,460 m. The view to the right is the Great Rift Valley daring you to look over—sheer, wide, and suddenly intimate. To the left, Nairobi sits low and sprawling like a city relieved of its confines.
