Lake Guinas — Deep Blue Sinkhole, Divers & Photographers

A twin sinkhole to Otjikoto, Lake Guinas is about 40km west of Tsumeb and significantly more dramatic in its depth and water clarity. Less visited than Otjikoto, it rewards photographers with extraordinary reflections and vivid blue-green colour. The lake is popular with experienced cave divers — depths are substantial and the underwater topography is complex. Access is via private farmland; check local operators for access and guided dive arrangements.
