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.

You might wonder what the checkbox that says “Include archived clues” on the Search Clues page means.

This is a way for those that are interested in viewing clues that are normally hidden. This is usually because the letterboxes are thought to be lost but may also because the boxes have been removed by the planter. The important point is that if you follow the clues, your chance of finding a letterbox are slim. Still some people like to find interesting hikes or the potential thrill of finding a box that was thought to be lost!
