About a mile upstream from Grassington is Ghaistrill's Strid, similar to its namesake at Bolton Abbey but probably not as well known.
Park in the National Park Car Park off the B6265.
Turn left out of the car park and walk back towards the town centre.
Continue past Main Street and bear left down hill towards the bridge.
Do not cross the bridge, instead take the lane on the right adjacent to the "Welcome to Grassington" sign.
Take the kissing gate on the left and walk diagonally across the field toward the river. Follow the path for approx 1Km until you reach the "Strid"
