For the outdoor adventure/ extreme sport types make sure you sepnd a few days in Swakupmund to sandboard, quad bike, and take coastal flights. It is also easy to get to the lunar scape and Cape cross from here.
It is just a whole lot of fun!
Though we arrived in winter (august), SWK is the main holiday center for water sports, beaches and coasts, but anyway, don't expect more than 22°C in summer!! The water, even in summer, is bloody cold, but there are a lot of good restaurants and loooong sandy coasts.
Walking around SWK you can find beautiful examples of german architecture that talk about its colonial past.
About two kilometres before you arrive in Swakopmund, on the left side of the highway, you'll see a rusty old steam engine. It was brought to the area in 1896 to transport goods from the township to the interior, but after a couple of trips it gave up the ghost and died on the spot. It is affectionately called Martin Luther, in memory of the German reformer's famous words on the steps of Worms Cathedral: 'Hier stehe ich, ich kann nicht anders' (Here I stand - I can do no other).
Swakopmund: a hint of Bavaria existing precariously between the Namib desert and the south Atlantic Ocean. Drive the skeleton coast, where the ocean mists swirl inland, get permission to visit the uranium mine, stare at the salt flats, and return to the town for the local beer and German food.
Swakopmund is the extreme sports lover's dream. We went sand boarding in the morning and quadbiking in the afternoon. I could have stayed several more days just to take advantage of the other trips.
