I can get permits for 10 people for kloofing in Grootkloof on 14 April. This will entail a 1 hour hike to the top end of the kloof, 2 to 3 hour descent of the kloof which will include an abseil, short swims and a few small optional jumps. Then a 20 minute hike back to hotel for beers, lunch etc.
Let me know if there is interest in this so that I can confirm the permits. I want to limit this to 10 otherwise the abseil becomes a bottleneck. We can do another round if there is further interest.
