HIDDEN across the ancient expanse of Dartmoor are a series small, seemingly inconspicuous containers: said containers, however, house something rather special.

The containers in question each have an ink-stamp inside and are what's known as a 'Letterbox' - they make up a Letterbox walk dubbed the 'I Spy on the Moor' walk.

The walk, which is around one and a half miles long, links ten boxes using clues: clues include such things as map grid references, paces from objects and more.

Clue sheets cost £3, with all monies going toward Bovey Tracey Swimming Pool.
