" What about a game of geocaching? Halfway between the ultra-modern treasure hunt and orienteering, this is the original way to discover unusual places along its walks. Beware, you quickly become addicted! "

Geocaching is a real-world, outdoor treasure hunting game using GPS-enabled devices. Participants navigate to a specific set of GPS coordinates and then attempt to find the geocache (container) hidden at that location.
