Sandy Crag (marked as Key Heugh on some maps) has a small selection of climbs but there are some real gems amongst them. The longish approach means that the place is never busy, though the extra effort involved in making a visit here on the right day will be repaid many times over. The routes are amongst some of the tallest on Northumbrian sandstone and are well divided between hard bold aretes and safe but strenuous cracks.
