There is a fantastic looking climb above the lake at Flaget, alas it was dripping wet when we tried. Its a three pitch WI5/6.
Just park up and stroll across the lake. Around the corner, to the right, is a small fall with several lines of WI3 to 4+, but it's right in the Sun.
Park where the road ends (or at least ceases to be ploughed), walk up the track to the bridge then walk upstream for ten mins and you will find a cracking little set of climbs (that really aren't that little!)
Two pitches believe it or not!
To the left of this are a couple of easier routes and to the right a small pillar.
There looked to be some lines on the headland north of Grov. We didn't bother climbing anything but you may fill a day there with some easier stuff. See the bottom left of the overview map.
