Geocaching is an outdoor treasure-hunting game in which the participants use a Global Positioning System to hide and seek caches anywhere in the world. A typical cache is a small waterproof container containing a logbook and "treaure", usually a toy or trinket of little monetary value. Also common are objects that are moved from cache to cache, such as Travel Bugs or Geocoins, whose travels may be logged and followed on line.
This high tech adventure game requires using a GPS with waypoint coordinates to find the cache. When one finds a cache one:
- adds an item
- may take an item from the cache
- record your visit in the logbook
- replace the cache in the same position, location and condition you found it
There are many types of caches. Some are easy enough to be called "drive-bys", "park-n' grabs" or"cache and dash". Others are more difficult to locate, including staged multi-caches. They may be found underwater, 50 feet up a tree, after long offroad drives, on mountain peaks, etc.
There are a number of websites that list geocaches around the world.The first website ever published and most well known is www.Geocaching.com.
How serious is this game? There are now some 167,818 caches in 215 countries and expanding.
