Another location would be the Tugela Falls area in the Northern Berg. There are 4 caches definitely available, (GC496EN, GCGCEM, GC496FW, GC1YX6K) and we could possibly even find all 6 on the plateau. I would not recommend the other 2 caches in the area which would require rope! It is quite possible to do this with only 1 night spent camping out, and you do not need to be super fit to make it.
