From the layby overlooking the Lune River and M6 we follow the lane towards Roundthwaite village. We shortly take a bridleway left to follow the Roundthwaite Beck as we start our ascent using open access land to reach Jeffreys Mount. We continue keeping to the higher path and grassy tops of Borrowdale Edge towards Casterfell Hill, Belt Howe and our highest points at Winterscleugh and Whinash.
As the Shap Road becomes evident we take a wider gravel track called Breasthigh Road as it zig zags down towards Crookdale Beck where, if the river is not in spate, we can cross at the stepping stones. If this is not possible, we can cross using Hucks Bridge on the Shap Road. Now we are on the valley floor following a good gravel path alongside the Crookdale Beck towards Low Borrowdale. We continue until we reach the A685. We carefully cross the A685 and then pass underneath two bridges, the M6 Bridge and the West Coast Main Line. At Salterwath Bridge we take a footpath through mature beech tree woodland alongside the river Lune. We again cross over the Lune at Lunes Bridge and return to the layby.
This area feels remote with mostly good paths, but some areas can be boggy. At the beginning and end of the walk there is a wonderful contrast between the vastness of the open fells in the Tebay Borrowdale Valley and the communting corridor of the M6 and West Coast Main Line.
Cross Key Pub in Tebay for refreshments.
