At the given coords you'll find an old fashioned red phone box.
The phone number is (01223) ABC DEF.
B side the 'phone box'
The cache coords are: N52 0(C-1).A69 W000 0D.C91 - a
few miles from the phone-box, and only a short walk from the
road
Parking is no problem - there is some tree cover at the last
moment, and you may need to walk through some nettles on the
way...
An interesting spot, with some history and a bit of view - After
you've visited the cache, Google should should reveal the full
story.
I discovered this site thanks to Pharisee's cache a
couple of miles away - a much shorter walk here though!
