Letterboxing is an intriguing “treasure hunt” style outdoor activity. Letterboxers hide small, weatherproof boxes in publicly-accessible places (like parks) and post clues to finding the box online on one of several Web sites. However, clues to finding some of the most highly-sought boxes are passed around by word of mouth.

There are about 60,000 active letterboxes listed on LbNA alone. Individual letterboxes usually contain a log book, an often hand-carved rubber stamp and occasionally contain an ink pad. Finders make an imprint of the letterbox’s stamp on their personal log book, and leave an imprint of their personal stamp on the letterbox’s logbook.

Once you’ve found a letterbox, please make sure to seal it back up so that it‘s watertight, then re-hide it so that it is completely hidden from view. I try to sprinkle a few leaves over the hiding spot to make it looks as natural as possible.
