Take the B1 until Rehoboth (the last petrol station before you reach Kuangukuangu is at Rehoboth).
About 5 km after Rehoboth, turn right onto the C24 until you reach Nauchas.
Turn right onto the D1275, which will take you over the Spreetshoogte pass. About 20 km further on, you will see, on your left, a fence saying "Barchan Dune": turn off. Here you take the private road to go to the guestfarm of Willem and Hannetjie (3km), who will welcome you and will show you where Kuangukuangu is located. You will then discover your own accommodation in Namibia.
It takes approximately 3 hours to go to Kuangukuangu from Windhoek or from Swakopmund.
