Dartmoor is a national park in Devon, considered an area of great beauty. It is a moorland region, and one of its particular features is its tors, mounds of granite which can be found all over the moors. It is also home to its own breed of wild pony, as well as the Dartmoor letterboxes, which are hidden at various points and can be found using clues.
