Ghaub Cave — National Monument & Guided Cave Tours (Near Otavi)

Namibia’s third-largest cave system, declared a national monument, on the guest farm Ghaub between Otavi and Grootfontein. The cave descends 38m and contains 2.5km of chambers and passageways with impressive stalactite and stalagmite formations. Guided tours are available on request at the Ghaub guest farm. A rarely visited and genuinely spectacular underground experience — far less touristy than better-known African caves.
