This GPS track covers the route from the top of KaNtuba Pass to Vergelegen Car Park. Aside from short bits of trail along the way, there is no trail between leaving the Nhlangeni trail and the escarpment. There are trails in the region of the Sulphur Springs, but we basically bypassed these.
KaNtuba Pass tops out at roughly 3300m, making it the highest high berg pass. It is well worth the effort, so enjoy it!
