In reply to NicholasHart:
The bouldering's superb, perhaps the best mid-grade destination in the country. I didn't find that Fleswick Bay was worthwhile though (seeps amazingly and is a bit of walk if there's nothing to climb). The Rockfax Lakes bouldering guide is excellent with good photo topos, although the first time I went I didn't have a guide and there are plenty enough great looking lines just to go and try the obvious stuff.
I wasn't aware that the bouldering was affected by restrictions, check the BMC website.
