Geocaching is an outdoor treasure hunting game where participants use GPS-enabled devices to find hidden containers called geocaches around the world. There are over 1.6 million geocaches hidden globally. To find a geocache, you enter coordinates from the geocaching website into your GPS, then search the area discreetly for a hidden container. Once found, you can trade small trinkets and log your discovery online. Geocaching encourages exploration and adventure while connecting people through the worldwide game.
