The North Entrance –– which includes the Kellogg Creek Picnic Area, the John Muir Interpretive Center, Watershed Office and the dam — is located on Walnut Blvd, just south of Brentwood.

The South Entrance — which includes the Marina and shore fishing — is located off Vasco Road, just about 4.5 miles north of Livermore.
