The cache itself is a 1 litre sistema, it's located somewhere along the Empire Pass track, just beyond the Fairy Falls. The Fairy Falls drop in several stages of cascades, with the track crossing the creek just below the top falls and continuing down until you are under the falls. If there has been a lot of rain recently, you may not be able to cross the path at the falls to get to the cache location.
The D/T rating on this cache reflects the original placement. The new location is slightly higher terrain. The RowBot, now 11, found it easy to access when she selected the spot.
