2021-10-14 12:30 Gribben (120) - Found it
I arrived here just after 12:30 only to find another walker there. He was as surprised to see me as I was to see him!
He departed after a quick chat and I was left alone again to search for the cache.
I took the opportunity to have a bit of lunch, then spotted a newt in a nearby pool just as I was leaving.
