Mam Tor and the Great Ridge: The Castleton Circular

A 517-metre hill with a paved path to the top, an Iron Age hillfort on the summit, a ridge walk east that never drops far, and a road at the bottom that the hillside destroyed. It is the best moderate walk in the Peak District.

Published 18 August 2026

Mam Tor stands at the head of the Hope Valley, right on the boundary between the gritstone Dark Peak and the limestone White Peak. That position is why the view works: Edale and Kinder Scout to the north, the Hope Valley and Win Hill to the east, and the limestone country falling away south toward Castleton.

The shivering mountain

The name means "mother hill", and the local name is the Shivering Mountain, because it is actively falling apart. The hill is built of alternating shale and gritstone, and the shale beds slump, which has produced one of the largest landslides in Britain on its eastern face. The most visible consequence is the old A625 below: the road was repeatedly broken by the moving hillside and finally abandoned in 1979. You can still walk down the wrecked carriageway, which is buckled and torn like something out of a disaster film and is genuinely worth the detour.

The route

The standard circular is around 5 miles with roughly 350 metres of ascent, and takes most people three hours at a walking pace with stops.

StageWhat happens
Castleton to Mam NickUp the road or the field path to the National Trust car park below the summit
Mam Nick to Mam TorA short, steep, fully paved climb to the summit and the hillfort ramparts
The Great RidgeEast along the ridge over Hollins Cross and Back Tor to Lose Hill, the best mile of it
DescentDown to Hope, or back over Hollins Cross into Castleton for the shorter loop
Cutting back at Hollins Cross turns it into a 4-mile round trip; carrying on to Lose Hill makes it a proper half-day.

The whole summit approach is flagged. That makes it doable in trainers on a dry day and passable in poor weather, but it also means it is busy. This is one of the most-walked hills in England.

Parking

  • Mam Nick (National Trust): closest to the summit, and full by 9am on a good weekend.
  • Castleton: the village car parks, adding the climb up but giving you the pubs at the end.
  • Hollins Cross from Edale: the northern approach, quieter, and handy if you are coming by train.

Edale has a station on the Manchester–Sheffield line, which makes this one of the few Peak District classics that genuinely works without a car.

Castleton itself

Worth an afternoon on its own. Four show caves, Peak Cavern, Speedwell, Treak Cliff and Blue John, sit around the village, and Blue John stone is found nowhere else in the world. Peveril Castle stands on the crag above. Covered further in things to do in the Peak District.

Common questions

How long is the Mam Tor circular walk?
The full Great Ridge circular from Castleton is around 5 miles with about 350 metres of ascent, roughly three hours. Turning back at Hollins Cross shortens it to about 4 miles.
How high is Mam Tor?
517 metres. The path to the summit is paved the whole way from the Mam Nick car park.
Why is Mam Tor called the Shivering Mountain?
Its alternating shale and gritstone beds are unstable and slump continuously, producing one of Britain’s largest landslides on its eastern face. The slippage destroyed the old A625, which was abandoned in 1979.
Can you walk Mam Tor without a car?
Yes. Edale station is on the Manchester to Sheffield line and the climb to Hollins Cross starts from the village, which makes the Great Ridge one of the most accessible Peak classics by train.
