Be aware that if you come down to the dam on the lake you can't escape through the valley, there's a gate on both of these minor roads coming down off the dam with some very threatening signs. You have to take on one of the bastard ramps, east or west doesn't matter, they're both brutal, though I can imagine eastward is worse.

A lovely place with great views, with a variety of walking trails on offer. Please note that the majority of the trails are closed annually from 1st October to 1st March, this is to protect over-wintering wildfowl, for which the area has been designated an SSSI.
