Namibia has the Namibian Dollar, Botswana the Pula (which means ‘rain’ by the way, the most valuable resource in these semi-arid regions), in South Africa you pay with Rands.Sure, in some establishments you can also pay in USD or Euro, but we advise you never to do that. It will turn out more expensive and there is simply no need.Virtually everywhere you can pay with your European debit or credit cards (don’t forget to ‘open’ them for international use). Of course having some cash at hand might come in handy, for in small grocery shops, souvenir stalls, tipping,… Bringing stags of cash into the country is really a thing of the past: in all cities and towns there are ATM’s of which most should accept your card.
