Thaba Bosiu lies 25 km east of Maseru on the road toward Roma — a flat-topped mountain rising sharply from the plain, with steep cliffs on every side. A short path leads up through the gap that once formed the main defensive pass, and the summit holds the ruins of Moshoeshoe's homestead and the royal graveyard where the founding king and several of his successors are buried.
The visitor centre at the base offers compulsory guides — about M150 plus tip — and the walk up and around takes roughly two hours. Allow extra time for the cultural village below, which gives a good introduction to traditional Basotho life.
