UKC Logbook Description
A massive pitch with 20 bolts and 3 contrasting technical grooves! Start from the left fork of the Twll Mawr entrance tunnel, make some cool steep technical moves out of the tunnel to gain the attractive groove system above. Follow the well bolted tricky grooves to some wider easier grooves and on to the pocketed and crimpy black dolerite band before joining the final square cut groove of 'Black Holes and Revelations' .
NOTE: The wobbly rusty ladder was not used on the first ascent, 7a+ if this is used as a point of aid, at least 7b without according to repeat ascensionists.....
