Geocache Policy

Olivenhain Municipal Water District Geocaching Policy

The Reserve’s mission is: “To safely operate Elfin Forest Recreational Reserve and to provide all visitors with a unique recreational, educational, and environmental experience.” The Reserve recognizes geocaching – a treasure hunt that utilizes the Global Positioning System (GPS) and the internet to find caches – as a recreational experience. However, not all areas of the Reserve are suitable for geocaching due to sensitive habitat. This geocaching policy was developed to facilitate responsible geocaching such that the Reserve can meet its mission.
