The road between the A1 and A24 just outside Union Mills is called the Lhergy Cripperty. I'm aware that the word "Lhergy" means Slope, and that "Cripperty" means Wrinkled (thanks to monstermunch for the translation). Hence, Lhergy Cripperty could roughly be translated as "Wrinkled Slope". Apologies if I'm incorrect.
If you look NNE from the point where the cache is located, you will see a number peaks in the distance. They are (from left to right) Carraghan (1,640ft), Beinn-y-Phott (1,785ft), Snaefell (2,037ft), Mullagh Ouyr (1,611ft), and Slieau Lhean (1,539ft). In the foreground, you will see the villages of Glen Vine and Union Mills.
The cache is now a small container with swaps. Parking is available right at the location of the cache.
