Nanyuki sits at about 1,900 metres on the northwestern slopes of Mount Kenya, straddling the equator — there is a sign on the main road marking the exact line. It is a market town of some size, with a distinctly military character thanks to the large British Army training base nearby, and it serves as the main gateway for the Sirimon and Burguret trekking routes onto the mountain.
The town itself is not a destination; it is a base. Climbers and hikers pass through to sort permits, buy supplies, and sleep before an early start. But the setting is extraordinary: when the cloud lifts you have direct views of the mountain's jagged peaks, and the surrounding landscape of highland forest and savannah supports wildlife including elephant, buffalo, and black rhino at the nearby Ol Pejeta Conservancy.
