(S/E) From the car park entrance in Keld, walk out past the farmhouse and take the track ahead, with an information board on your right and a stone barn on the left.
(1) Pass another barn in the field on your right, then turn left and descend the steep wooded path to the River Swale. Cross the footbridge and climb the hill to a track by East Gill Force (the Pennine Way to the left provides a return route to Tan Hill).
Turn right above the waterfall and go through a gate. Climb to a second gate and contour above the woods leading down to the Swale. The track bends left and right past a barn.
(2) When it divides, for the shorter, easier route stay on the lower (right-hand) track, descending to cross Swinner Gill at a footbridge by the ruins of a lead mine and rejoining the described route at step
For the longer and more difficult route to Swinner Gill lead mine, take the left fork and climb the hill to the ruin of Crackpot Hall. Just before the ruin, take a stony track on the left, climbing alongside spoil-heaps to another, higher ruin.
Continue to a gate with a dramatic view of Swinner Gill.
(3) Follow the narrow path along the valley side, then descend to a stone arched bridge over the stream which gives access to the ruined building at the lead mine.
Returning over the bridge, turn left and take a lower path that runs along the top of the crags to the right of Swinner Gill (take care). As you descend towards the stream there is a short rocky scramble where you may need to use your hands.
(4) Pick your way across the stream above a small waterfall and locate a narrow path in the bracken beyond that leads to a stile over a wire fence. Follow the path along the steep valley side until the crags above peter out.
On reaching a fence, turn right and descend steeply to the track at the bottom.
(5) Turn left. Cross a small side-stream and follow the track with the River Swale on your right. Continue along the track for a mile. When the track starts to climb, take a narrow path on the right that leads along the top of a small cliff and then turn right again (signposted Muker) and descend to Rampsholme Bridge.
(6) Cross the bridge and turn right, now heading upstream with the river on your right. Ignore the path to Muker on your left and continue to a stone barn.
The path continues along the valley across fields, passing another barn on the left before dropping through a gate and continuing through riverside fields. Below a wooded slope, the path leaves the river and passes some more old barns (to left and right).
(7) Level with a ruined farm the path climbs gently above the valley bottom, passing more barns with views over the river to the spoil-heaps and assorted buildings of Beldi Hill Low-Level lead mine, a scheduled monument with several visible remains including the mine level.
Beyond a gate in a wall, the path enters an area of trees and bracken and continues to climb, becoming rather rocky under foot.
(8) Just beyond an old lime kiln on the right, the trees open up and there is an optional detour to Kisdon Force, via a gap in the wall that gives access to a narrow path that descends through bracken to the river, steeply at the bottom (care).
Returning to the main path, turn right and continue towards Keld up the brackeny hillside. The path then descends below a limestone cliff and the Pennine Way joins from the left. Pass a signpost to Kisdon Upper Force.
Continue along the top of a wood with fields on your left, passing the junction with the outward path, and continue back to Keld. (S/E)
