Sometimes known by its alternative name of Saddleback, Blencathra (868m) looms along the skyline northeast of Keswick, and (alongside Skiddaw) represents the toughest hiking challenge in the area. The usual route starts in Threlkeld and loops around the fell's east side over Blease Fell, a steep climb that's well worthwhile for the panoramic view. It's about 5 miles return.

There's a more challenging route to the top via the rocky ridge of Halls Fell, but a third route via Sharp Edge is best left for experienced scramblers and rock climbers – it involves sheer 300m drops and makes Helvellyn's ridges look like child's play.
