About RAC & Sheep Pen Boulders

Two closely-linked bouldering venues on the north side of the Ogwen Valley, up on the moorland plateau above the A5 to the west of Idwal Cottage. Both share the same compact patch of open mountainside with superb views back down the valley; 15 minutes' walk from roadside parking. Cool, dry conditions preferred — the rhyolite gets slick in warm sun.
