This is a 6.1-mile (9.9 km) circular walk from Maggie's Bridge, with about 558 m of ascent. Allow roughly 3 to 4 hours for the full circuit. The route follows the track through High Nook Farm, climbs past Highnook Tarn and over the rough ground of Gavel Fell, crosses the damp saddle at Fothergill Head, then climbs to Blake Fell before descending back toward High Nook.
The climbing is steady and sometimes steep, but the main difficulty is the combination of boggy ground, rough grass, stiles and faint paths. It is a remote-feeling fell walk rather than a maintained summit path. There is no technical scrambling on the described circuit, although the descent beside Highnook Beck is steep and needs care.
