A wee hide along an excellent hiking track. As others have written, this is an excellent loop to do, taking about 4-6 hours if you walk it, and around 6-8 hours if you cache it. 
We walked clockwise around the track, and we all agreed it was the better way to do it, in terms of saving your knees. When the cache was placed, I was here with some friends, one of whom was Marc, who suggested the place.
Take good note of the weather, and bring lots of water when it's hot. Wear proper footwear, and bring a friend or six for some laughs!
