Tuesday 3 September. We made the short drive this morning to the nearby village of Bainbridge for a 7¾ mile walk with 1,300ft of ascent. We walked upstream alongside the east side of the River Bain to its source which is the outflow from Semer Water; North Yorkshire’s largest natural lake. This was fairly gentle but on leaving Semer Water we had a climb of over 800ft, some of which was 1in4 in places. The climb, though steep, was only about a mile and took us to the top of Green Scar Crag. From here we walked across open moorland to meet up with Cam High Road; now a farm access track but originally built by the Romans. We followed this in a very straight line for just over 2 miles before picking up a path on the west side of the River Bain and back to the car.
