This Cache is not quite at the source of the river, as I believe it is on private moorland.
I have therefore placed it on a beautiful stretch of moorland, within 1 mile of the source, a couple of hundred metres from the road, so to give a small walk.
Careful
It is boggy on the walk to the cache site, with sheep paths to follow, on a 45 degree sideways slope. A small stream crossing is called for at the cache location- Grannies I would not advise !
The 4.5 star terrain is to warn people that its not a drive by !
