START from the Cavendish Pavilion car park off the B6160 just north of Bolton Abbey, turning by the memorial fountain.

Barden Fell access area can be closed on a limited number of days for grouse shooting (August-December) or at times of high fire risk, though is usually always open on Sundays.

Check accessibility by visiting boltonabbey.com.

Cavendish Pavilion stands on the River Wharfe’s bank at the entrance to Strid Wood, with refreshments and gift shop.

Cross the bridge and take a broad path upstream.

Entering trees at a gate it forks, take the upper one zigzagging onto a road, and rise left to a brow.

A gate on the right alongside Waterfall Cottage is the start of a permissive path leading to the moorland access area.

A green track heads left past the cottage to a gate, where a firmer track winds along to fade by a pond, with Posforth Gill just ahead in the Valley of Desolation.

This title refers to the aftermath of a great storm in 1826.

Turn right along the rim of the steep drop to the beck, noting a viewpoint for a super waterfall.

The path resumes high above the beck to cross a tiny footbridge on it, then continues along the valley floor.

Before long it slants left up to a gate into a plantation. Head directly away on a broad track ascending to a gate at the far end onto a corner of open moor.

Follow the wallside track directly ahead.

The wall turns off and Great Agill Beck is crossed prior to a steep, stony section.

At a stone table Truckle Crags and more distantly Simon’s Seat come into view.

Beyond the table a track branches right: here you rejoin the outward route on returning from the top.

For now, you should follow the broad ascending track which curves left to cross the beck’s headwaters before you then reach a fork.

As the track swings left, bear right on the broad, sometimes rocky path past Truckle Crags.

The larger group of rocks atop Simon’s Seat are now only minutes away on a peaty but largely dry path which marches directly towards the summit.

An Ordnance Survey column at 1591ft/485m occupies the highest rocks, and hands are needed to attain it.

Along with a fine Yorkshire Dales panorama is a bird’s-eye view of the Appletreewick area.

To vary the return, take the initially fainter path heading east to the huge rocks at Lord’s Seat: almost at once this transforms into stone flags.

Just beyond the rocks a wall is reached, and the flagged path turns right alongside it to commence a gradual descent.

After a while the head of a good track is reached, and this quickly leads down to a junction.

Turn right away from the wall, and the wide track undulates across the moor back to the outward route near the stone table.

Retrace your steps to the start of the walk.
