Overview

A scenic autumn walk through forestry and across open moorland, with the possibility of some fine views... there is plenty of scope to adapt to weather conditions though.

Wednesday, 26 November 2025
Start time:
9:30 am
Estimated finish time:
4:30 pm
Difficulty:
Strenuous
Distance:
21.7km / 13.5mi
Ascent:
411.5m / 1350ft
Type:
circular

There will be rough forestry tracks and some rugged moorland terrain, which may be boggy after rain. The walk does not entail any big climbs, but is graded as strenuous because of terrain and pace.
