The Shivering Mountain — a ridge that crumbles in slow motion above a broken road.
The ridge crumbles in geological slow motion, taking the old road with it, while the path along the summit holds firm above the broken tarmac below. Mam Tor in the Peak District, Derbyshire, is the Shivering Mountain — a ridge so unstable it destroyed a main road and a Bronze Age fort, and so compelling it draws walkers who don't mind the ground moving beneath them.
Mam Tor rises to 517 metres at the head of the Hope Valley, its eastern face a series of landslip scars where alternating bands of shale and gritstone collapse under their own weight. The A625, built across the base of the landslip, was abandoned in 1979 after repeated repairs failed to hold the moving ground — the broken road surface is now a monument to the mountain's instability. The summit holds the remains of a Bronze Age and Iron Age hillfort, one of the highest in England. The Great Ridge Walk from Mam Tor to Lose Hill follows the ridge above Castleton, with Edale to the north and the Hope Valley to the south. The walk connects to Castleton's show caves — Peak Cavern, Speedwell Mine, Treak Cliff Cavern — making a circular route that covers both surface and underground geology.
Solo
Walk the ridge alone when the cloud base sits at summit level and the valleys vanish below. The broken road at the base, visible from above, tells the mountain's story in fractured tarmac.
Couple
The Great Ridge Walk is one of the finest short ridge walks in England — exposed enough to thrill, sheltered enough to talk. End in Castleton for a pub supper beneath the castle.
Friends
Combine the ridge with Castleton's caves for a day that covers the Peak District above and below ground. The scramble, the views, and the underground — the conversations write themselves.
