Connecting to the centre of the summit horseshoe, producing a shape not unlike a tuning fork in plan, is Harter Fell's third ridge.

This ridge is all together rockier in character and leads swiftly down to Nan Bield Pass for onward connections to Mardale Ill Bell and High Street.

The western slopes of the fell above Kentmere Reservoir are moderately steep, with an area of historic landslip surrounding Dry Gill.

The summit horseshoe of Harter Fell forms the head of Wren Gill, the main headwater of the River Sprint in Longsleddale.

With the submergence of Mardale Green village beneath Haweswater reservoir in the 1940s, their original purpose has died, but both routes still provide good access for fellwalkers and are the easiest ways onto Harter Fell.

[citation needed] As well as a pile of stones, the summit cairn of Harter Fell carries many pieces of ironwork salvaged from the fence.

The view is good all round and can be improved by moving to the rim of the crags, bringing the full length of Haweswater into sight.
