Hardknott Pass is a hill pass between Eskdale and the Duddon Valley in the Lake District National Park, Cumbria, England. The tarmac-surfaced road, which is the most direct route from the central Lake District to West Cumbria, shares the title of steepest road in England with Rosedale Chimney Bank in North Yorkshire. It has a maximum gradient of 1 in 3 (about 33%). Etymology The pass takes its name from Hard Knott which is derived from the Old Norse harthr (hard) and knutr (craggy hill). Geography A single track road runs between Eskdale in the west to the edge of the neighbouring Wrynose Pass in the east. On the western side is Harter Fell and the remains of Hardknott Roman Fort ( above sea level). The Hardknott Pass stands at a maximum elevation of . The road descends steeply at a gradient of 30% (1 in 3) into the Duddon Valley. At the eastern end of the pass is Cockley Beck farm, built in the 1860s and owned by the National Trust. The route from Hardknott leads eastward towards the Wrynose Pass and Ambleside. The pass is described as one of the most challenging roads in Britain. A series of hairpin bends make visibility difficult in various places, and the road surface is in poor condition and slippery when wet. The pass is often closed in winter due to ice that makes the route impassable for vehicles. Traffic ascending the pass has priority as advised by the Highway Code. The challenging 1 in 3 gradients, steeper than the mountain stages of European bicycle races including the Tour de France and the Giro d'Italia, draw endurance cyclists. It is part of the annual Fred Whitton Challenge, a 112-mile ride around the Lake District. An "average" cyclist who was trained over six weeks for a 2019 Eurosport documentary called England's Toughest Climb failed to complete the route. History A road over the pass was built by the Romans around AD 110 to link the coastal fort and baths at Ravenglass with their garrisons at Ambleside and Kendal. The Romans called this road the Tenth Highway. The road fell into disrepair after the Romans left Britain in the early 5th century, becoming an unpaved packhorse route used to transport lead and agricultural goods. By the early Middle Ages, it was known as the Waingate ("cart road") or Wainscarth ("cart pass"): there is an
