The nearest town is Clanwilliam, at the bottom of the pass 15-20 min drive on a dirt road from the climbing. The tourism information office's # is 027+(0)27 4822024. The first 027 is the international dialing code, drop it if you are already in the country.
Half way between Clan William and the campground is the Klein Kliphuis which is effectively a bed and breakfast. Not stayed there before but meant to be nice.
