How do I start geocaching at Trinidad Lake State Park? Get current geocache coordinates from www.geocaching.com. Simply plug those coordinates into your GPS unit and navigate your way to the cache. Most GPS units are accurate to within 3–6 meters, so you may have to spend some time searching for the hidden cache. The visitor center attendant can give you the general area where the cache is located and tell you whether you need to drive or hike there. GPS units are available for rent at the Trinidad Lake State Park Visitor Center for a small fee. Make sure to place the cache back in the same spot where you found it so that other visitors may have the same experience that you did! Here are some Trinidad Lake travel bugs and geocoins that you can follow: Reilly Canyon Rover (Travel Bug), South Shore Stroller (Travel Bug), and Trinidad Lake State Park 1 (Geocoin) For the latest on geocaching and other park activities, follow us on Facebook.
