Restricted Access

Due to suspect rock and the proximity of the public road, climbing is only permitted on routes which are between the green painted marker posts and have fixed lower-offs. Routes and areas of cliff between the red painted posts are banned due to instable rock and the risk of falling rock injuring passers-by. All routes finish at BMC installed and maintained lower-offs - and on no account should climbers continue beyond these to the top of the crag due to the increased risk of falling rock and to protect rare and protected plant species.

No climbing on the routes above the Marine drive before 6pm between July15th until Sept 8th this includes Mayfair Wall, the restriction extends to bank holiday weekends as well. Please adhere to this agreement (due to public safety issues during busy times) as it has taken a lot of work to secure access to these crags.

All the bouldering and the climbing in Parisellas's Cave and Mumbo-Jumbo areas are however permitted.

Rockfax Description
One of the great challenges of the crag. Most climbers do the route in one pitch, by climbing the first pitch, clipping in, pulling the rope through to reduce rope drag, and then continuing. Start below a large flake corner.
1) 6a. Climb up to a bolt and make a hard move to good holds directly above. Move up and slightly left to clip bolts on Harry the Clamp. Step right, crossing the corner on huge but friable holds and up to a double-bolt belay.
2) 6b. Traverse right past two bolts via a hard and blind move to a scoop and a good rest. Pull leftwards out of the scoop to gain a huge pocket. Climb thoughtfully up the headwall to the top. © Rockfax
