Top Definition
Destination point, usually a container with small objects and/or toys, for a GPS based orienteering sport/hobby called "Geocaching" after the web site of the same name. Participants hide containers (or sometimes objects, clues, or virtual objects) and publish GPS coordinates and hints on the Gecaching web site. Others seek the geocache as a form of recreation and may exchange items for those in the geocache, as well as reporting (online) the success or failure of their search.
When we travel to another city, we often will bring a GPS unit and search out a local geocache as a way of becoming more familiar with the area.

Geocaching (pronounced geo-cashing) is like a high-tech scavenger hunt, made possible by Global Positioning System (GPS) and the Internet. Originally developed by the U.S. Department of Defense for military applications, GPS technology has been free and available since the mid-1980s. Although many people use GPS receivers to aid in navagaition, the systems also have recreational uses, such as recording locations of caves, hiking trails, and favorite fishing spots.
