Welcome to OpenCaching North America.
Geocaching is an outdoor sport or activity in which cachers use a GPS connected device to find hidden containers placed by other participants. Caches contain items for exchange and a logbook in which the finder records their discovery of the cache. Finds are then recorded digitally on the OpenCaching website where the coordinates of the cache's location are stored along with the description and instructions necessary to find it.
OpenCaching North America is completely free to use and is maintained by member volunteers.
