Winter Hill is a hill near the boroughs of Chorley, Bolton and Blackburn with Darwen, in North West England. It is located on Rivington Moor and is 456 metres (1,496 ft) high. Part of the West Pennine Moors, it is a popular walking area, and has been the setting for mining activity, aeroplane disasters and murders.
Its prominent position made it the ideal site for the Winter Hill TV Mast, transmitting to a large part of North West England. There also a number of other telecommunication masts and towers around the summit and side of the hill for mobile phones, Professional Mobile Radio users and emergency services. Lancashire Constabulary was the first to use the site for one of their base stations in 1950
Paths to the summit lead from Belmont, Horwich, Rivington and Bolton, but the summit can be reached via a short walk from the top of a road pass 2 km west of Belmont. The hill is a distinctive feature on the skyline for most of the Borough of Chorley and further afield due to its unusual shape.
