Most of my caches involve a lovely walk with fine views and usually atop a volcano, this is not one of them.
This cache is a challenge to find the entrance to the valley.
The most feasible way of entering the valley is at either end so that is the only help you will get.
BUT there are a number of warnings you need to heed.
The valley is covered in rocks and walking through it is hazardous, for this reason it is NOT suitable for children.
Walking shoes are strongly recommended.
Because of this, the cacha is not hidden under any of the rocks on the valley floor.
It is under a small cairn in a small shallow cave.
Please ensure that the cache is replaced in the cave and a small cairn built, this minimises the risks underfoot.
