THE CACHE IS NOT IN OR ON THE DRY STONE WALL. PLEASE DO NOT DISTURB THE WALL.
There is parking near the Carman Reservoir. We leave it up to you to choose your route. You can scramble straight up the hill, or you can head west along Carman road for about 500 meters and then turn right into the track. There's a well defined path until you reach the dry stone wall. Turn right, walk along it and you should reach GZ in no time.
You will be rewarded with spectacular views (on a nice day) looking east towards Alexandria/Balloch and Pappert Hill with the Campsies in the distance. Facing south you see Carman Reservoir, Dumbarton Rock, the River Clyde and beyond.
You're looking for a 50ml tub.
We placed this cache on the 2nd of May 2020 as part of our daily local walk during lockdown. Checked it on 5th June.
