This long ditance route is a high level traverse of the Pennine watershed beginning in the Calder Valley at Burnley and finishing in the Aire Valley at Bingley. From the start of the walk in Towneley Park the route climbs to the Pennines via Fother Royd Wood, Hurstwood, Hameldon, Black Moor, the Gorple Reservoirs, Alcomden Water, Black Dean, Crimsworth Dean Beck and Lumb Hole Waterfall. The Pennines are then crossed via Naze Hill, Flaight Hill, High Brown Knoll, Bob Hill, Midgeley Moor and Warley Moor Reservoir to the highest point of the walk at Nab Hill. From the high point the way continues down to Thornton Moor Reservoir, Whinny Hill and Black Moor before the West Yorkshire village of Cullingworth is reached. Harden Moor is then crossed before the walk terminates in Bingley.
