This must be the easiest pass in the entire berg (yes, easier than the Chain Ladder route) as it tops out at only 2500m after an easy trundle up a Little Berg ridge. Thamathu Pass is used as the descent route for the Grand Traverse but it's certainly worth doing when you're feeling like a pretty chilled hike. The views of Thaba Ngwangwe and the Devil's Knuckles are impressive and some interesting rock formations can be seen on the way up.

Difficulty of the pass is rated from 1-10 (10 being very difficult, only to be attempted by the fit and experienced). A subjective quality rating is indicated by the number of stars (1 being low, 5 being the highest). Factors such as scenic beauty and overall experience come into play here, which may differ from person to person.
Follow the path straight up the ridge from the Bushman's Nek Border post for 8km to Thamathu Cave at 2300m.
The distance from Thamathu Cave to the top of Thamathu Pass is 3 km with an altitude gain of 300m.
From Thamathu Cave, simply follow the clear path up the ridge until you reach the escarpment slopes (no cliffs here!). The path contours out to the right for a further 1km before you suddenly round a bulge after some boulders and find yourself looking into Lesotho.
Finding the pass from the escarpment:
Follow the path heading towards the escarpment edge from Lesotho and keep to the right. The path rounds a large escarpment bulge and then heads down the pass.
Thamathu Cave is huge and has a nice lawn outside it to relax on. No other camping spots (the ridge is quite exposed to lightning) until the mother of all camping spots, the escarpment itself.
The only water on the pass is found at in the river flowing next to Thamathu Cave. On top, a 200m walk will get you to water in summer.
