Damflask Reservoir Circuit

Forty-seven hectares of open water inside the Peak District National Park boundary, five miles from the middle of Sheffield, with a made-up perimeter path that was widened and resurfaced so wheelchairs and buggies can get round it. Three rowing clubs and the Viking Sailing Club use the water, so there is always something moving on it. Yorkshire Water asks for dogs on a lead and off the water: it states plainly that it is not safe for dogs to swim here or drink from it, because of blue-green algae, cold water and machinery under the surface. The circuit starts and finishes in Low Bradfield, where there are pubs, a cafe and public toilets, and the going is level all the way round.
