What is geocaching?

Geocaching is an outdoor recreational activity where individuals, groups, or families search for hidden containers known as geocaches by navigating to them using a hand-held Global Positioning System (GPS) receiver.

Caches may be found in your neighborhood, in local parks, along city streets, or half-way around the world. Geocaches have been registered on every continent including Antarctica. There are even some geocaches underwater!

Geocaches are often hidden near areas of historical significance or natural beauty, often leading you to discover places you may not have found if not for the cache there. The cache itself may be any waterproof container, from an aspirin bottle to a large, metal box (ammo box).

All you need to enjoy this family-friendly activity is a GPS unit or GPS-enabled cell phone, internet access (to find cache locations and share your finds), and a sense of adventure.

What is GPS?

GPS stands for Global Positioning System and refers to an electronic navigation system that can pinpoint your location anywhere in the world, usually to within fifty feet or less. The system consists of twenty-four satellites that circle the earth twice a day and continuously broadcast location information. GPS receivers, either hand-held or car-mounted, use the signals from between four and twelve satellites to calculate a location.
