Deep in a valley framed by oak-covered hills, with sailboats and sailboards skimming over its waters, Del Valle is like an alpine resort only 10 miles south of Livermore.
Centerpiece of the park is a lake five miles long with all kinds of water-oriented recreation, surrounded by 4,316 acres of beautiful land for mountain biking, trail running, and nature study. Del Valle also is the eastern gateway to the Ohlone Wilderness Trail, 28 miles of scenic back country trail.
