The Dam Long Walk is a strenuous walk which is intended to be completed in one go but which can be broken down into stages if necessary. The walk explores the Dark Peak area of the Peak District National Park/ South Pennines. The walk is circular and throughout its course it visits 32 dams and reservoirs surrounding Black Hill. From the start at Crowden Youth Hostel the walk visits the River Etherow series of reservoirs, namely Torside, Rhodeswood, Valehouse and Bottoms before climbing from the valley past Arnfield Reservoir and the upper reaches of Hollingworth to cross Wild Bank Hill on Hollingworthall Moor. The next series of reservoirs is then reached; Walkerwood, Brushes, Lower and Higher Swineshaw. Next Ormes Moor is crossed to reach Chew Reservoir before the Chew Hills are crossed to the reservoirts of Dovestones, Yeoman Hey and Greenfield. Upland walking across Saddleworth Moor and Featherbed Moss come next to reach Black Moss and Swellands Reservoirs which are soon followed by the reservoirs of Redbrook, Butterley, Blakeley, Weseenden and Weseenden Head. The Kirklees Way is next folowed to a succession of five reservoirs, namely Digley, Brownhill, Ramsden, Yateholme and Riding Wood. Cook's Study Hill is passed to reach Snailsden Reservoir and soon afterwards the Winscar Reservoirs are reached. The Windleden Reservoirs follow before heading back for home via Woodhead Reservoir back to Crowden. That is an awful lot of moor and water behind you.
