There are several options to get to this cache, the closest from the Tall trees car park
which is a shade over a mere 200 metres to walk each way, from the southwest side of the visitor centre along the Lady Barron Falls track or as part of the circuit walk taking in Russell and Horseshoe Falls
The walk take you through tall forests of swamp gum (Eucalyptus regnans) and stringy bark (Eucalyptus obliqua) and are good quality all weather tracks.
Due to the tree cover the GPS reading may not be as accurate as desired, however the hint, if you want to use it, should be a big help. The photo will also let you know when you are at the right spot.
Replace the cache carefully in the cradle.
