Part 2: Continues on top of Birkdale Common then the entertaining and panoramic descent to Nateby. Turning left and heading South now past Pendragon Castle and Outhgill. Gently climbing along the Mallerstang valley and turning right (carefully) onto the A684. You’re quickly off the main road, turning left at Garsdale and the steep climb over Coal road and the even steeper descent, down to Cowgill. Watch out for those final very tricky hairpins! Turning left and another climb up through Stone House to turn right on the B6255. Fast and flowing descent to the Ribblehead Viaduct, turning left and still gradually descending through Horton-in-Ribblesdale to Stainforth. Final big climb now, with Pen-y-ghent on your left, over the moors and descend to Halton Gill. Turn right and it’s pretty much downhill all the way back through Litton and Arncliffe and back onto the B6160. Through Kilnsey and turn left at Threshfield back into Grassington.
