Some 30 km outside of Calitzdorp in the Western Cape is the Gammkaberg Nature Reserve, run by Cape Nature. There are a number of trails in the park, the longest (two days) is the Tierkloof Trail that runs up the Tierkloof canyon stops at Oudkraal, an over night camp and then returns to the base camp the next day. Both days distance is about 14 km. The scenery is magnificent and the going moderately hard. The first day ends with a climb of about 450 m over 3 km. The second day is easier with a sharp down hill and then fairly flat all the way home. I recently hiked this trail and it is, as claimed one of the more beautiful hikes in the Western Cape.
The base camp.
Setting out
The trail is built on and around the river that carved the klook (canyon). The river does not run often so this is not a problem. It could get tense though….
Elements of the Cape Fold Mountains can be seen.
Thorn trees growing in the riverbed.
Trail markings are very good, this is an informal one that took my fancy
At Overhang, about halfway there and back. 
Overnight camp – Oudkraal.
Sunset is a special time
And the stars are spectacular
Down again.
And relax
Enjoy the sunset
Before the long road home
