Just north-east of Brassington stands the windswept heights of Harborough Rocks. The grey limestone has in parts been dolomotised (converted to magnesium carbonate) that has resulted in outcrops of a distinctive fawn-coloured rock which has a porous texture. This has helped to make the rocks into a mysterious feature with a cave and some interesting weathered formations. At above 1,200 ft the rocks provide a stunning viewpoint.
