plenty of tradding on both heads: info on right-hand heads in mcsa jornals of the late 70's. otherwise just do it. i've opened a number of routes of between grades 17 and 20 (from 1-5 pitches) on the right-hand head which is easily accessed by driving up to the top (which is an airfield - accessed from within the town).
also, some deep-water soloing between 2nd and 3rd beach (rising traverse, basically, with grade options, on a west facing wall above a deep gulley) and on a north-facing wall above a gulley to the west of 3rd beach - obvious, if you're looking for it.
As one of the previous respondents suggested, there's good climbing on \"Waterfall Bluff\" , east of Mboyti, with excellent single pitch tradding in the gorge above the main waterfall, and plenty of bouldering in any of the gullleys above the other waterfalls.
Let's not forget the excellent climbing (of between 15 and 50 metres) in the vicinity of the \"Coffee Shack\" (backpackers lodge ib coffee bay) abseil site between Coffee bay and Hole-in-the-wall
basically, all these areas, like most of the eastern cape, is brsitling with climbable rock.
