The cache is not at the posted co-ordinates.
This is, however, a good place to park, both for the Adventure and for this cache. This is the bonus cache for the nearby Adventure lab - One Track For All. Once you have completed the five stages of the adventure lab then you will receive the actual coordinates for this cache.
The Adventure is on a wheelchair-friendly path and, as long as you stay on the path you are well away from cliffs. However, there are side tracks which may approach cliff edges, so please keep an eye on children if you leave the main track. The container for this cache is not readily accessible by someone sitting in a wheelchair.
Please replace the container as found and ensure it is covered by natural camouflage.
As you follow the path from stage to stage, the compass in the Adventure Lab app will sometimes appear to point back the way you came. This is because the path loops back on itself. Just keep following the path.
