The title is nothing to do with Pat Cash but refers to the stunning little mountain (only a 'Graham' - not a 'Corbett' or 'Munro') above the village of Glencoe.
It can be reached from the col to the east of the summit by a short rocky path, with plenty of scrambling possibilities if you like that thing 
. The col can be reached in an hour or two via a boggy path which leads off the road a little way up-valley from the parking spot.
The summit of the Pap of Glencoe is at N 56 41.330 W 005 03.776
A little to the east of the summit is a cairn dedicated to a 2 year old who died in a road accident.
About 40 feet downhill on the north side from this are 2 large boulders. The lower of these has a little triangular cave on the downhill side and the cache is on the RHS of this behind some small rocks.
The cache is a screw-topped circular black plastic tub containing a log book, pencil & a few goodies.
A HUGE THANK YOU to TeamShannagh for putting a fresh log sheet in place in Summer 2021 when the old one was no longer usable. I'm very grateful to you.
