decent, no. But there are a couple of traverses on ok limestone at a place called Haresfield Beacon which, if I recall, is sort of Stroud way. Best to get the OS Map (or have a look at one in Cotswold). Park at Parking Area, and there is one of those things telling you what you can see in each direction (whatever they are called). Walk south through a nice grassy field until you see a fence on the left. Skirt this on the left side and you will find a limestone wall bay, and a lower wall with a good traverse. I know these diections are pants, but its about 4 years since I was last there. I'm sure there was an article in High about some stuff in the Forest of Dean, otherwise there is Bathford, near Bath (ssh) and Ladye Bay near Portishead.
