This experience will take you to a once thriving industry which hacked huge amounts of precious granite from Millstone mountain in the beautiful mountains of Mourne. Several interesting artifacts and many remnants still remain to learn from. Information boards will add to this wonderful hiking experience.
The cache container is a small tuppaware container which contains a few swaps. Also a log book. Hidden very close to the 'wee' house, hence the name! (Apparently, this little building was once explosives store for quarry production) Many thanks to Landyliam for this fascinating information.
Enjoy your experience and be sure to take water, food, compass, sensible mountain clothing / footware. Oh and your camera for sure. Some fabulous views await you.
p.s. cache is hidden out of sight to preserve these wonderful mountains (tucked in safely under a large rock). Also take a few items of trash out as it is not uncommon to find rubbish on the mountains.
