I was there yesterday and did some bouldering just off the road above Sanna - amazing rough gabbro for padding - and bouldered at Sanna Wall (beach). I also added some new routes (possibly) on a wee chasm just on the beach side of the Sanna wall. Great trustable friction ! Added a topo photo of this to the Sanna Wall photos.
A long drive but a unique place with climb anywhere crags littered close tot he road. Must go back soon.
