What is Geocaching?

Geocaching is a high-tech treasure hunting game where the objective is to locate geocaches (caches), or hidden containers, outdoors with the help of a Global Positioning System (GPS)-enabled device using coordinates that are posted online. Players of all ages, levels of physical fitness, and tech savviness enjoy exploring the world around them this way and then sharing their experiences online.

Currently, there are over one million geocaches hidden around the world and over five million registered geocachers. Prompted by the game's growing popularity in the San Francisco Bay Area, the District in 2007 published its Geocaching Guidelines to allow for responsible geocaching on District lands. Please visit our Guidelines and FAQ page for more information about geocaching within our open space preserves.

For the Newbie:
