Hi Peter,
As I'm sure you know, the Khomas Hochland is huge! That means you can
take the direct or not so direct route. And I suggest you take as
indirect as you have time for! Just to name a few of the passes (apart
from the other attractions), there are Kupferberg Pass, Bosua Pass, Us
Pass, Gamsberg Pass, Spreetshoogte Pass, Remhoogte Pass...! The scenery
everywhere is breath-taking.
To give you an idea, see attached for the two day-route that we
travelled in that area in January. Despite taking two days, of course we
didn't include everything, and the days were still full.
It's advisable not to travel some of the passes with a trailer or
caravan. They are Bosua Pass and Spreetshoogte Pass if memory serves. If
it's important to you, the last but one (?) DriveOut has a description
of the passes (which doesn't do them justice but covers the
trailer/caravan issue), or check with a local establishment like Hakos
Guest Farm or Solitaire.
All roads there are gravel, generally wide and well maintained.
Subsequent to the recent rains maintenance teams might not have caught
up with all work, so caution is advised in depressions where water might
have crossed the road.
Enjoy!
Francois
