This is a 6.5-mile (10.4 km) circular horseshoe, measured for the complete loop from Hartsop village car park. It climbs Hartsop Dodd, crosses to Stony Cove Pike, drops to Threshthwaite Mouth, climbs Thornthwaite Crag, then traverses to Gray Crag before descending to the Hayeswater track and returning to Hartsop. Allow about five hours for a steady walking pace with summit stops.
The first climb is steep but straightforward on a grassy ridge. The high traverse follows walls and open fell paths, with a rough, loose descent from Stony Cove Pike to Threshthwaite Mouth and another sustained climb to Thornthwaite Crag. From the beacon, the route-finding becomes more important: pick up the less obvious path north toward Gray Crag rather than drifting onto the busier High Street route. The final descent from Gray Crag starts pleasantly, then steepens onto slippery grass before reaching the well-surfaced Hayeswater track.
