Well after I said that I wouldn’t reveal the location of the crag I went to today i decided that to hell with it, everybody will find out, so might as well help you to get there. It was a venue called Craig Y Tonnau, it is situated between betws-y-coed and bleaneau, just off the A470. As you drive from betws to bleaneau you’ll pass through a small village call Dolwydelan, just after the village you’ll pass the castle, then the road eventually passes over the river, a little further along is a turn signposted to one of the more remote and unused railway station (Roman Bridge).
Take this road and follow it passed one hairpin right and then a another less obvious one left, pass through a farmyard, and continue on past a gate, just past this is a open flat area in front of a house. Park here and follow the track into the forest, after 300metres is a line of telegraph poles, leading left into the forest, follow this along a feint path, until at the high point of the poles, after about 45m the path leads over a small ridge and down to the crag. Enjoy
