Malham Tarn circuit

A four-and-a-half-mile circuit of England's highest marl lake, two hours on estate tracks, a stretch of quiet moorland road and grass paths, with almost no climbing at 375 metres above the sea. Park at the National Trust car park at Water Sinks on the Malham to Arncliffe road; Malham village and its toilets and tea rooms are three miles south. The Trust asks for dogs on leads and bars them entirely from the boardwalk through the National Nature Reserve at the east end, so plan to walk the road section instead; sheep and cattle graze the upland farm land, and the tarn shore gives easy shallow access for a drink.
