Together with its smaller twin, Little Dun Fell, which reaches 842 m (2,762 ft),[1] it forms a stepping-stone for the Pennine Way on its long climb up from Dufton.

Alfred Wainwright abhorred the old radio station (removed in the 1980s) in his book Pennine Way Companion.

This road is marked as private from just above the village of Knock, and is not open to public motor vehicles.

[2] The University of Manchester formerly had a permanent meteorological observatory at the Great Dun Fell site.

[3] There are the remains of hushing gulleys on the slopes of the mountain, created during lead mining of the Industrial Revolution.
