Haslingden Grane is a glaciated valley lying to the west of Haslingden and in the north east of the West Pennine Moors. It is easily accessible via the B6232 Grane Road which links to the M65 motorway and the A56. It contains three reservoirs: (west to east) Calf Hey Reservoir, Ogden Reservoir and Holden Wood Reservoir.
Prior to the construction of the reservoirs in the 19th century the settlement of Haslingden Grane had a population of 1,300 and was the centre of an illegal whisky distilling industry. The remains of some buildings can still be seen. Much quarrying has taken place in the past and continues at Jamestone Quarry.
The valley is overlooked to the north by Oswaldtwistle Moor and to the south by Musbury Heights. The attractive moorland scenery makes it a popular place for walking especially through the well known Fairy Glen beauty spot, there is an information centre, parking and cafe at Clough Head.
