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. The Himba people, a local, indigenous people, can also be found in the area, and is close to the Skeleton Coast, so you can organize your trip from there.
One of the most enjoyable activities in a desert is sandboarding, or surfing the dunes. Swakopmund is in the Namib Desert where several companies offer this service. Ask where you're staying and they will put you in contact with organisers. The day you go sandboarding they will pick you up and take you to the best dunes. Yes, the truck can not climb to the top and you have to walk, which is quite good as it will make you think about the climb up as well as the way down. It can be difficult in the heat to carry boots and a board. But when you're sliding down the dunes with the wind blowing and seeing the sea in the background, it is worth it. When the activity is over there is a picnic on the shore of the sea, and then they take you back to the hotel. The company offers helmets, boards and boots, plus picnic food. Take litres of sunscreen. When I did it in 2009 it cost about 30 €.
