Taxis, shuttles and your own wheels
There is no useful public bus network for visitors in Windhoek. The centre is easy on foot by day, and for everything else you use taxis. Shared taxis run set routes from ranks and charge a flat fare per seat, around €1, and more if the driver takes you off the main roads into residential streets. The FCDO advises against hailing taxis on the street, especially in Windhoek, so ask your hostel to call a driver they trust, or use LEFA, the local booking app. Uber does not operate in Namibia.
Hosea Kutako International Airport is about 45 km east of the city on the B6, around 40–45 minutes by road. There is no public transport to town. Hostels and shuttle companies run transfers for a per-person fee, and private transfers start from about €62 for two. Street taxis at the airport are unmetered, so agree the price before you get in. If you're hiring a car, pick it up at the airport and skip the transfer altogether.
Car hire is how most people travel Namibia. All the international firms have desks at the airport, and local 4x4 specialists deliver to your hostel. At handover, check the tyres, both spare wheels, the jack and tools, the windscreen and the underbody, and photograph every scratch. Ask what the insurance excludes. Many policies don't cover single-vehicle accidents, tyres or windscreens unless you pay for an upgrade. You need your licence plus an International Driving Permit, some cash for fuel in small towns, and a plan to finish each drive before dark.
On the road, keep to around 80 km/h on gravel, which is where most crashes happen. The FCDO advises two spare tyres and plenty of water, especially in the January to April rains.
For Swakopmund, Intercape runs a daily coach of about five hours, and Town Hoppers runs a door-to-door shuttle. Shared minibuses leave from the long-distance ranks too.
