In reply to philipjardine:
I may be wrong but I don’t think there is currently anything more up to date than than the old cheddar/Avon guide. The CC southwest guide is newer but not comprehensive and only has a couple of routes.
All the routes are on here though and it’s a small enough crag that you can work out where everything is from the descriptions. There’s not that much that’s brand new from the old Cheddar guide anyway but some routes have newer/more bolts than they used to.
