Where to do it: Garriochmill, at the bottom of Queen Margaret Bridge (?) in Hillhead

How to do it: The tunnel in the picture is part of the base of the bridge running above.
This is an easy scale up as the ornamental gaps are wide enough to find good grip and foot holds. Climb upwards like a lizard...climb sidewards if you are a crab. Enjoy the quietude around you.
