A varied walk linking three villages in Upper Swalewdale. Good riverside paths from Keld, then field paths to Muker and Thwaite, returning to Keld on the Pennine Way.
From Keld the walk passes Kisdon Force before following the river Swale. Passing Swinner Gill a good track reaches a bridge then joins paved paths through meadows to Muker. Ongoing meadow paths continue to Thwaite, a pretty village worthy of a detour before returning to join the Pennine Way. After a short, steep climb the path contours around Kisdon Hill before returning to Keld. From Thwaite the path is narrow, rocky and wet in places. The views of Swinner Gill from the Pennine Way section are excellent.
