A simple way to describe geocaching is that it combines the latest in the world of technology with one of the oldest "sports" around - treasure hunting. Geocachers, armed with a GPS, can seek out the hidden caches in California or any other state utilizing GPS coordinates posted on the Internet by those hiding the cache. Following directions given by their rented or purchased GPS, they navigate to the hiding spot of the cache.

There are countless hidden caches you can discover with a rented GPS in California, from downtown San Diego to the state's more rural areas. A cache can be large or small; easy to get to or require a lot of trouble to reach; and then can be hidden at different degrees of difficulty. No geocache should be buried, however, so no digging is required. A great resource for lists of hidden geocaches to search for in California is this page on the geocaching.com site. You can refine your search by zip code, town or a nearby address from there.

Once you've identified a cache in California you wish to navigate to, you need a GPS to lead you there. No GPS will take you exactly to the spot, but should get you within about 20' or so. At that point you need to use you eyes and brain! Good GPS units to use for geocaching searches include the InReach handhelds, DeLorme handhelds, Garmin eTrex, Lowrance trail models and Garmin GPSMap Series as examples. Sometime there are clues in the write-ups about the cache that will help you finally find it once you get close with the GPS. A cache is typically a waterproof container discreetly placed within the local terrain, including a logbook and inexpensive items such as small paperbacks, toys, coins, costume jewelry, trinkets, etc. Look around for something that seems just a bit out of place. You never know what the founder or other visitors of the cache may have left for you to enjoy.
