The Lake in the Ingleborough Eastate Trail, near the village of Clapham in the Yorkshire Dales.
The tiny valley of Clapdale was damned in the early 19th century to provide water for the village. Since 1893 the water has powered turbines to generate electricity for the estate and to give Clapham the first street lighting in Yorkshire. Reginald Farrer used a shotgun to fire rock plant seeds onto the cliffs at the far side of the lake.
Admission charge to The Trail.
