Swakopmund is located about four hours away from Windhoek, Namibia's capital. To get there you can take the Intercape bus line, or if you prefer, take vans or even the train.
The people are very nice. The city was founded by the Germans and still retains its German colonial architecture. The streets are clean and well-maintained, and have a delicious smell of sausages (no joke). It is rather surprising that people still speak German there.
It is on the coast, with the sea on one side and the desert on the other. When I went in April it was cold. It is a good place for activities such as sandboarding.
