Geocaching is a relatively new activity that combines hiking, treasure-hunting and the Global Positioning System (GPS). For more information on GPS, you can read the wiseGEEK article titled: What is GPS?
Geocaching involves two separate parties, which are composed either of individuals or groups. One party hides a cache anywhere in the world and records the latitudinal and longitudinal coordinates using a portable GPS device. The cache is usually composed of a small plastic container that houses some small items such as toys or coins.
The coordinates and related information regarding the location of the hidden cache are publicized, usually on internet sites such as geocaching.com. Geocachers search for these hidden caches using their own portable GPS devices in conjunction with maps and clues. When they finally discover the cache, they may take a few of the items and leave a few different ones for future geocachers.
Geocaching is a popular new hobby and provides yet another reason to explore the world around us. Discovering a hidden cache after a long search is a surprisingly rewarding event. There are thousands of caches all over the world waiting to be discovered by anyone who wants to participate.
As geocaching becomes more and more popular, some participants are adding new levels of complexity to keep it interesting. For excample, some geocachers hide caches in particularly difficult locations such as underwater or up in a tree. Some geocachers hide caches in series such that a first cache includes instructions to discover another cache and so on.
