In reply to Obi Wan:
Pretty much everything mentioned here is in Bristol Esoteric Bouldering (Great Western Rock) available from Dicks Climbing as you pass through Bristol.
You may want to include these as they are beautiful and/or have caves as well
Draycott Sleights(good blue cheese also)
Burrington (caves/prehistory)
The White Cliff on Wavering Down(pubs below)
Mells River -Vallis Vale, Great Elm, Mells - interesting geology, great walk, good climbing, good cafes and pubs and Frome Boulder Rooms when it rains
