Not to be confused with the Ngong Hills, the Ngong Forest Sanctuary is another managed forest in the west end of the city, in Jamhuri, about 6 km from the CBD. It’s one of the few designated forests in the world located within city limits, and it’s a great place to explore the natural flora of Kenya. The best running options in the forest are the 5 km perimeter loop and the trail heading east from the Dagoretti Police Station. The terrain consists of narrow dirt paths running along seasonal rivers and wetlands. After rain, there can be some mud, but these lush woods are a cool place to outrun the heat.
