Thaba-Bosiu is Lesotho’s great national monument. It is a flat-topped hill which was used by Moshoeshoe I as his citadel when establishing the nation. It is within easy reach of Maseru. The substantial remains of the King’s dwellings and villages and the royal cemetery of Lesotho are on top of the hill. A tarred road leads to a small information centre. From there visitors have an easy climb up Rafutho’s Pass (where the Free State Boer commander Louw Wepener was killed in an attack on Moshoeshoe I in 1865) to the summit plateau and the remains of Moshoeshoe's village. The views from the summit are lovely.

Guides are available at the tourist office.

Buses and taxis run to the tourist office at the base of the mountain from the southern bus rank in Maseru.
