In reply to ericinbristol:
There is shitloads in the Forest of Dean!
Huntsham is good quality and you could spend all day just on the first lot of boulders just up from the track (Rift and Sliced Slug etc...)
For another nice setting, check out '3 Rocks' near Ruspidge, lots of low 6s. Ive just added it to UKC but its also in the Roots Supplement guide (pdf).
Bristol Bouldering guide will show you everything. Ive heard Elwood is good too...
