The range begins in the north at Wrynose Pass and runs south for around 10 miles (16 km) before petering out at Broughton in Furness on the Duddon Estuary.

Brim Fell stands at the junction of the three arms with the northern branch continuing over Swirl How and Great Carrs.

It provides a crossing from Coniston village to Seathwaite in the Duddon valley and was originally constructed both to facilitate local trade and to serve the many slate quarries on these fells.

[1] South of White Pike is a profound drop to an area of rough country before the shapely pyramid of Caw rises skyward.

To the west long and gentle slopes run down from the summit of Dow Crag toward the Duddon, while further north on this flank is Seathwaite Tarn.

This was originally a much smaller waterbody, but was dammed early in the 20th century to provide drinking water for the Barrow in Furness area.

This stream passes a disused quarry near the Tranearth climbing hut, keeping the workings topped up via an artificial but extremely picturesque waterfall.

The view south and west to the coast is excellent, but much of Lakeland is blotted out by the flanks of the Coniston range.

[4] The simplest direct routes begin at either end of the Walna Scar Road, making for the summit from the top of the pass.

Ascents can be made from Seathwaite Tarn (pathless) or to the north of Goat's Hawse, but these give no clue to the grandeur of the crag on the eastern side of the ridge.
