Almscliff Crag is a Millstone Grit outcrop at the top of a small hill near the village of North Rigton, between Leeds and Harrogate in West Yorkshire, England. The crag was formed due to the softer adjacent strata of shale and mudstone eroding at a faster rate than the hard wearing millstone. The crag is one of the best climbing locations in the area. Some classic climbs include Parsons' Chimney, Black Wall Eliminate, and Wall of Horrors.
