What is Geocaching?

Geocaching is a real-world treasure hunting game using GPS-enabled devices such as a smart phone. Participants navigate to a specific set of GPS coordinates and then attempt to find the geocache (container) hidden at that location. See Geocaching 101 for all the information you need to get started.

A recent upgrade to requires a membership to see the DPL multi-cache series, older versions may still display all caches. The Cachly app is an alternate option. You may also print the cache descriptions in the DPL series and use another mapping app. We are looking into further solutions.
