Snake Pass is a hill pass in the Derbyshire section of the Peak District, crossing the Pennines between Glossop and the Ladybower Reservoir at Ashopton. The road was engineered by Thomas Telford and opened in 1821. The pass carries the A57 road between Manchester and Sheffield, but it is no longer the main signposted route between those two cities, with traffic instead directed through the Woodhead Pass to the north. Like several other roads that cross the Pennines, Snake Pass has a poor accident record compared with roads in the UK generally, although more favourable compared with other roads in the area. It is regularly closed in winter because of snow, and has seen several longer-term closures owing to subsidence following heavy rain. The road remains a popular route for tourists and motorcycles, however, and sections have been used for semi-professional cycling races such as the Tour of Britain. Route and location Snake Pass runs through the National Trust's High Peak Estate, and lies within the High Peak borough of Derbyshire; much of it falls within the Hope Woodlands parish, the remainder being within the Charlesworth parish. It is part of the shortest route by road from Manchester to Sheffield. The pass starts east of Glossop and climbs to the Pennines watershed between the moorland plateaux of Kinder Scout and Bleaklow to a high point of above sea level, where it crosses the Pennine Way. After this, it passes a public house that used to be known as the Snake Inn, and descends through forest to the Ladybower Reservoir at Ashopton. The name of the road matches its winding route, but actually derives from the emblem of the Snake Inn, one of the few buildings on the high stretch of road. In turn, the pub's name and sign were derived from the serpent on the Cavendish arms of William Cavendish, 6th Duke of Devonshire. In the early 21st century, the inn was renamed the Snake Pass Inn, such that the inn now refers to the road that referred to itself. History An ancient road between Glossop and Ashopton was the Doctor's Gate, which follows the Shelf Brook between Shelf Moor and Coldharbour Moor. It is marked on some maps as a Roman road, though this is disputed. The route is now popular with walkers and mountain bikers. In 1932, an Iron Age axe thought to be more than 2,000 years
