The cache itself is at:
S 11111 2000.4024
E 00224 0003.0397
This is what I consider to be a prime example of a puzzle cache. Once you've got your coordinates, plug them in and start hunting.
The cache itself is a standard painted plastic container in what I hope is a nicely hidden spot with the usual cache goodies. I've also discovered a much easier way to get into the location, so I may step down the terrain level shortly too.
Argh!!! After being so careful with the co-ords, I discover, I typoed my original. My apologies Mr Bear. It should be a lot easier to find now.
Update: 28th September 2022
Have visited and updated the cache with a new, albeit smaller, container. Same location, but hopefully slightly easier to find. The box below the new cache is the old cache. Don't open it, it was beyond saving but does make a nice plinth for the new one.
