Grimwith Reservoir

Grimwith Reservoir is one of the Yorkshire Dales' hidden gems tucked away off the road between Grassington and Pateley Bridge.

Like Malham Tarn, this pretty lake set in the lap of Raydale, a side valley off Wensleydale, is unusual in the Yorkshire Dales in being naturally-formed. The pure waters of Semer Water have supported a wonderful variety of wildlife for thousands of years ever since the last glacier melted leaving it behind.

Malham Tarn

In leaky limestone country, surface water usually eventually finds its way underground. Malham Tarn is unusual because here the water doesn't sink into the ground.
