Reservoirs of Teesdale and Scenic Valleys

Teesdale’s reservoirs are some of the most peaceful and scenic places in the North Pennines. Built to supply water to the wider region, they now provide quiet escapes for walkers, birdwatchers and anyone looking to spend time in nature. Each reservoir has its own character from the wild moorland shores of Cow Green to the gentle valleys around Grassholme and Selset offering stunning views, rich wildlife and a deep connection to Teesdale’s geological past.

These reservoirs are not just bodies of water. They are part of the story of the land, shaped by ancient volcanoes, Ice Age glaciers and later by people working with nature. Today they offer walking routes, fishing spots, dark sky viewing areas and peaceful places to pause and breathe in the stillness of the valley.

Below you will find each reservoir with easy to read information including parking, walking opportunities, whether you can swim or fish, and what makes each one special. This page is your simple, friendly guide to exploring Teesdale’s reservoirs with confidence.
