Route Grade Votings
Steep and powerful climbing up the edge of the cave of Bertram's Chimney. Start inside the cleft and climb for 10m, then swing out left to gain the front face. Power up this (old pegs) until it is possible to swing left and gain some respite on The Spider. Finish up this.
Pegs are old, but a good in-situ thread on on the left protects the crux.
