There is a great day in the hills to be achieved by finding the GCs along the route from the parking in Glen Trool over Benyellary over Merrick back to Glen Trool. Since finding these old GCs, new ones have appeared.
Start by parking near
Bruce's Stone GC, head up the path towards
Culsharg Bothy, before ascending on to the summit of Benyellary and GC. Cross the ridge to trig pillar on top of
Merrick, your high point. Now drop down to
Grey Man of Merrick Earthcache by going west to avoid crags.
Once EC found and recorded, pick up Buchan Burn to forest track back to parking.
Or for a really big day out, after Merrick EC, find Loch Neldricken GC and Loch View GC before returning towards parking via View of Glen Trool GC.
Big day on the hill. Wear midge repellent sunscreen.
