Riyom Rock is a spectacular stack of granite boulders about an hour's drive south of Jos, near the town of Riyom in the southern part of the plateau. The formation rises sharply from the surrounding farmland — three large boulders balanced on top of one another, with the topmost stone seemingly tipped at an impossible angle. It is one of the most photographed landmarks on the plateau.
You can drive close to the base and walk up. A short scramble brings you to a viewpoint where the surrounding villages and farmland spread out below; on a clear day the views across the plateau are excellent. Allow half a day from Jos including travel. As with any longer-distance excursion in Plateau State, check the current security situation before you set out and consider going with a local driver who knows the area.
