Tsumeb is the main town in northern Namibia and the practical gateway to Etosha National Park, roughly 70km to the west. It's a working mining town — copper, lead, zinc, and silver have been extracted here since German colonial times — and a useful stop for fuel, supplies, and a night's rest before or after Etosha.
Despite its utilitarian reputation, Tsumeb rewards a short detour. The Tsumeb Museum is genuinely impressive, covering both mining history and the remarkable mineral diversity of the local ore body. The nearby Oshikoto Lake — and the quieter, deeper Otjikoto Lake a little further afield — are striking natural curiosities worth a stop. Good supermarkets and several fuel stations make Tsumeb the sensible last resupply point before entering the park.
