the motorway the trail follows Blackstone Edge to the A58 road, then passes a series of reservoirs. It crosses the Calderdale Way high above the village of Mankinholes, then climbs to the prominent monument on Stoodley Pike. From the monument it descends steeply to the valley of the River Calder, which it crosses about west of the town of Hebden Bridge, the largest settlement near the route. The trail climbs out of the Calder valley through the scattered hamlet of Colden, crossing Colden Water by an ancient clapper bridge. It then passes the Walshaw Dean Reservoirs and climbs to the ruins of Top Withens, said to have been the inspiration for Wuthering Heights. The trail then descends to Ponden Hall, and crosses more moorland to the villages of Cowling and Lothersdale. From Lothersdale the trail crosses Pinhaw Beacon to Thornton-in-Craven. There then follows gentler country, including a short section of the towpath of the Leeds and Liverpool Canal at East Marton, to reach the village of Gargrave in Airedale, on the busy A65. Yorkshire Dales National Park North of Gargrave the Pennine Way ascends Airedale and enters the Yorkshire Dales National Park. It follows field paths, through the small villages of Airton and Hanlith to the larger village of Malham. It then climbs steps on the west side of Malham Cove, traverses the limestone pavement at the top of the cove, and continues north to Malham Tarn. The trail then crosses a shoulder of Fountains Fell, crosses the head of Silverdale and ascends the nose of Pen-y-Ghent in a very steep section. From the summit of Pen-y-Ghent the Pennine Way descends to the village of Horton in Ribblesdale (on the Settle–Carlisle Railway). The Pennine Way then heads up Ribblesdale along the old Settle–Langstrothdale packhorse road. It passes the eastern end of Ling Gill and climbs Cam Fell, where it follows the line of a Roman road, shared with the Dales Way. The trail then passes Dodd Fell Hill and follows a ridge between Widdale and Sleddale, before descending into Wensleydale at Gayle and the adjoining town of Hawes. The path crosses the dale to Hardraw, then begins the ascent of Great Shunner Fell. From the summit of the fell the trail descends to upper Swaledale and the village of Thwaite. It then crosses the side of Kisdon, with good views down Swaledale, passes Kisdon Force, a waterfall on the River
