About The Park

Deep in a valley framed by oak-covered hills, with sailboats and sailboards skimming over its waters, Del Valle is like a lakeside resort only 10 miles south of Livermore.

The centerpiece of the park is a lake five miles long with a variety of water-oriented recreation, from swimming to windsurfing and boating, surrounded by 4,395 acres of beautiful land for hiking, horseback riding, and nature study. Del Valle also is the eastern gateway to the Ohlone Wilderness Trail, 28 miles of scenic back-country trail.

Park Features

Visitor Center

The Del Valle Visitor Center is open weekends June through September; 9am - 4:30pm. The visitor center is on the lake's west side and contains exhibits and information about the natural history of Del Valle and surrounding wilderness. Campers and park visitors are encouraged to visit and talk with naturalists and student aides about the park and the lake and to take part in the exciting programs happening all summer long. Campfire programs at the campground amphitheater begin Memorial Day weekend; campers and park visitors are welcome to join naturalists for an evening of campfire fun, including songs, stories, games, and marshmallow roasting. Park visitors can also enjoy a scenic boat tour of the lake with naturalist staff. Purchase tickets at the marina store on the lake's east side at the boat launch area.
