Hardknott Pass

Hardknott Pass is a steep hill road in the Lake District National Park, linking Eskdale in the west with the Duddon Valley in the east. The single-track tarmac climbs between Harter Fell and Hardknott Roman Fort, reaching 393 metres above sea level. Its maximum gradient of one in three makes it one of England’s steepest roads. The route follows an old Roman road built around AD 110, later used as a packhorse track and cart road. The pass is often closed in winter because ice makes it impassable for vehicles. Cyclists and motorists still tackle the challenge despite the poor surface and sharp bends. The pass draws endurance cyclists because the climb is steeper than many mountain stages in European races. It features in the annual Fred Whitton Challenge, a 180-kilometre ride around the Lake District. A trained cyclist failed to complete the route on a 2019 documentary. The road’s history includes Roman garrisons, medieval packhorse routes, and 19th-century tourist schemes. In the 1940s the War Office used the area for tank training, damaging the old surface before it was repaired and tarmacked. Visitors find the remains of Hardknott Roman Fort beside the western approach, standing 200 metres above sea level. At the eastern end is Cockley Beck farm, built in the 1860s and owned by the National Trust. The road passes through open fells with wide views over Eskdale and the Duddon Valley. The route continues eastward towards Wrynose Pass and Ambleside. The contrast between the modern tarmac and the ancient Roman alignment adds to the pass’s interest.
