This route is one of the options of the Rotary Club of Harrogate's annual Nidderdale walks.
If you want a long distance, challenging route then this is the route for you. From Pateley Bridge, the walk takes the same path as the 15 mile walk via Wath, Bouthwaite, Ramsgill and Lofthouse where there will be a checkpoint. It is expected that there will be refreshments here. Turn left in Lofthouse and walk on the right side of the River Nidd up past Thwaite House and Summerstone Lodge. Continue to the Scar House reservoir dam where the 22 mile walkers cross the dam whilst the 26 milers walk around the reservoir. Return over In Moor to Middlesmoor and re-enter Lofthouse. Continue on the east side of the river to Bouthwaite and return the way you came to finish at Pateley Bridge.
