In reply to climbwhenready:
One of my favourite crags!
+1 for Central Tower. Also consider Wrinkled Butress (VD), Nobbly Wall (HVD), Swan Crack (HVD) and Question Mark (HVD).
It's a steep walk in if you park at Binn Green on the A635. You can walk up from the sailing club which is gentler but longer. They also have an ice cream van.
Note: if the weather is too wet for climbing consider a traverse of the Chew Valley Rim from Alphin to Alderman. Top walk.
