I’ve just done a couple of short walks on a part of Dartmoor which is definitely “real moor” but not remote, to plan this new trail and see where I might place the caches.
However, it is not easy. The obvious hides are in dry stone walls and in gorse bushes. The former is definitely a no-no and nobody really likes the latter. But the choices are very limited and will probably end up “under a rock” or somewhere on a tree!
