I took my first hike on the new Oak Cove Trail in Calero County Park today. It's a beautiful, mostly-flat trail that winds around the edge of the reservoir in and out of beautiful old oak trees. This cache is hidden on the Oak Cove Trail, about two miles from the main Calero parking lot. If you hike the entire Oak Cove Trail and come back via Serpentine Loop > Pena Trail, it's roughly an 8-mile loop.
You're looking for a regular-sized cache about 40' off the trail on the downhill side. Look for the title object, then look for a likely spot. If you were an ammo can, where would you hide? There's minimal camo, but it's not very necessary here.
Calero trail hours are sunrise to sunset. Happy hunting!
