The track up to the circle is marked as authorised access only for vehicles so if you can leave your car at the bottom, do so. The (uphill on the way there) walk is beautiful anyway! There’s a 3 car or so parking option maybe 20 yards before the fork at Cragg Hall, on the verge opposite a gate.
A glorious afternoon, with the frozen patches in the fields, and icicles where the tiny streams drop down to the track, glistening in the sunshine.
