Snake Pass is a mountain pass at an elevation of 510m (1,680ft) above the sea level, located between Manchester and Sheffield in Northern England. The pass is traversed by the A57 road.
The road over the pass is often closed in the winter months as the bending roads become icy, but it can be closed anytime when the access is not cleared of snow. The road has superb views and the scenery is exceptional, particularly at the start of the descent into Glossop from where you can see to Manchester and beyond on a clear day.
The surface of the road is asphalted and includes some steep sections. The road which passes over the high ground between the flatter moorland, as its name suggests is a winding twisty road with lots of elevation changes and adverse cambers, and can be very slippery in poor weather conditions. The road was first built as a toll road in 1820.
There are 2 routes to reach the summit. Starting from Ashopton, the ascent is 14 km long. Over this distance, the elevation gain is 302 meters. The average percentage is 2.2 %. Starting from Glossop, the ascent is 7 km long. Over this distance, elevation gain is 362 meters. Snake Pass is one of only a few road climbs in the UK that are comparable in length and average gradient (approximately 7% for around 3.2 miles (5.1 km) when starting in Glossop) to those used in continental cycle racing. For this reason it has frequently featured in the Tour of Britain.
