In reply to Red Rover:
Can't really see the route on that map but there is a lovely path around the edge of the quarry which then dips down at the north end and goes through a giant arch in the quarry workings to the edge of the water. Spectacular, far from boring and nice and short! Well worth adding in.
I've always been on a bike but I suspect you have to pay for parking. I could be wrong though.
