Otay Lakes County Park sits on a hillside above Lower Otay Reservoir, one of San Diego County's main water supply lakes. The 78-acre park has shaded picnic areas, a playground, and easy walking paths with views over the blue lake and the dry chaparral hills stretching south toward the Mexican border. It is a quiet, uncrowded escape from the suburban bustle of Chula Vista below.
The reservoir itself is off-limits to swimming but open to fishing (largemouth bass, bluegill, and catfish are common catches) and non-motorised boating with a launch permit. The park is the eastern trailhead for the Otay Valley Regional Park corridor, which runs 11 miles west to San Diego Bay. 2270 Wueste Rd, Chula Vista.
