Following the spine of the Pennine ridge from Dufton to Hartside Pass this linear walk passes over Cross Fell which is the highest point in England outside of the Lake District. Partly following the Pennine Way National Trail and partly on pathless moorland this route rewards with stunning views throughout, especially those across the Eden valley to the distant Lakeland Fells. This linear route is a serious undertaking in any weather, and to help with navigation it is described in both directions.
