Letterboxing is an intriguing pastime combining artistic ability with delightful "treasure-hunts" in beautiful, scenic places that the whole family can enjoy. Participants seek out hidden letterboxes by following clues, and then record their discovery in their personal journal with the help of a rubber stamp that's part of the letterbox. In addition, letterboxers have their own personal stamps which they use to stamp into the letterbox's logbook.
Clues are everywhere, and with experience comes an ever wider variety of clues at your disposal.
