About Dewerstone

Sheltered river valley — good when the moor is too wet/windy. Lower altitude = warmer. Multi-pitch granite in the wooded Plym Valley near Shaugh Prior, with steep vertical faces, clean corners, micro-crimps, and deep wire cracks. South-facing upper walls dry quickly; lower sectors stay shaded by trees and can hold moisture. Classic routes include Central Rib (VS 4b), Scimitar (E1 5b), Column (VS 4b), and Agag (E2 5c). Approach is a fifteen-minute uphill woodland walk from the Shaugh Prior car park.

Region: Devon — Dartmoor

Aspect: west-facing
