Bonscale Pike is a fell in the English Lake District, standing above Howtown on Ullswater.

From Loadpot Hill the ridge gradually narrows on the approach to Bonscale Pike, first crossing a marshy area and then the domed intermediate top of Swarth Fell, 1,788 ft (545 m).

Bonscale Pike stands on the north facing point as the boundaries of the ridge converge.

Swarthbeck Gill on the east – which separates the fell from its twin, Arthur's Pike – falls to Ullswater through a ravine.

A fair path runs along the ridge to Loadpot Hill, crossing the High Street Roman road to the south of Brock Crag, a number of old boundary stones being encountered on this route.
