Further north all the way to the top of Great Knoutberry Hill, followed by a westerly descent to rejoin the Pennine Bridleway near Green Bank. Anti-clockwise around the southern flanks of Great Knoutberry Hill, west via Arten Gill to Stonehouse Farm, and finally south back to Dent Head Viaduct along the minor road.

The best map to use on this walk is the Ordnance Survey map of the Yorkshire Dales Southern & Western Area, reference OS Explorer OL2, scale 1:25,000. It clearly displays footpaths, rights of way, open access land and vegetation on the ground, making it ideal for walking, running and hiking. The map can be purchased from Amazon in either a standard, paper version or a weatherproof, laminated version, as shown below.
