Parking
Start at Threlkeld Car Park, just off the A66 near the village. The mapped line begins a few metres from the car park and uses lower public paths, lanes and tracks before reaching open fell.

Knife-edge Grade 1 scrambling above a tarn, then a high ridge descent
Overview
This is a closed loop of 6.6 miles (10.6 km), starting and finishing at Threlkeld Car Park. That figure is the total distance for the whole circuit, not a one-way measure, so there is no return leg to add on. Expect roughly 2,500 feet (about 760 m) of ascent and a typical time of about 4.5 hours, plus extra for careful movement on the rock and for pauses on the ridge.
From the car park you pick up lower field paths and footpaths past farms and gills, then traverse below Scales Fell on a rising line into the coombe holding Scales Tarn. Above the tarn the ground steepens onto Sharp Edge, the arete leading to Foule Crag, then Atkinson Pike and the main top at Hallsfell Top (Blencathra). The return runs west along the summit ridge over Gategill Fell Top and Blease Fell, then drops on a long descending path back to the lower approach and Threlkeld. The climb is front-loaded and sustained, the top is broad and airy, and the descent is a steady giveaway of height rather than another sting.

Trail guide
This is the defining section of the walk, and scrambling cannot be avoided on the ridge. It is a Grade 1 scramble on polished, angular rock with unprotected drops on both sides and a notorious short crux, the Bad Step, where you commit to smooth slabs above steep ground. Hands are needed, and confidence with heights matters more than fitness here. Dry, calm, clear conditions are far more forgiving; wet rock, wind, snow or ice raise the seriousness of this ground considerably. If that description makes you uneasy, choose a different day or a different hill rather than starting the arete and hoping.
We rate this hard, 8/10. It is a full steep mountain day on rough rock and steep grass, with loose, uneven footing rather than a smooth graded path. Above the tarn and along the tops you need genuine high-level route-finding: the summit plateau and ridge lines are broad, and the correct descent over Blease Fell is easy to lose in cloud. Carry a map and compass and know how to use them, and wear boots with real grip. The lower approach and return are easier going but still uneven underfoot.
Start and finish at Threlkeld Car Park, with a short access offset at the car park itself and some lower public paths, lanes and tracks linking the village to the fell. Dogs are legally allowed on the public route under normal countryside rules, but Sharp Edge is a poor choice for most dogs: the scramble includes moves and drops that dogs cannot safely negotiate or be lifted through. Keep dogs under close control throughout and on a lead near livestock. No trail-specific permit is needed.
The hazards here are real and concentrated: exposure, a committing crux, steep rough ground and long descents that punish tired legs and poor visibility. It is also a popular hill, so you will likely share the ridge in good weather. If the scramble is not appropriate for your group, your dog, or the day, a shorter Middle Fell-only walk nearby gives a good half-day on the fells with big views and none of the scrambling.
