Los Vaqueros Reservoir

Los Vaqueros Reservoir

Los Vaqueros reservoir is operated by the Contra Costa Water District (CCWD). Much like nearby Del Valle Lake (maintained by EBRPD), the reservoir supports various recreational activities like boating, fishing, picnicking, and hiking. Being a source of potable water, swimming and pets are not allowed in the area.

Note that there are two entrances within the park that do not connect: in order to drive to the other side, you’ll need to exit and drive ~45mins on Vasco.

The area supports various wildlife including bobcats, raptors, coyotes, and egrets. The hikes here vary in difficulty from gentle, flat strolls along the lakeside to steep rolling hills.

Getting There

Los Vaqueros North and South Entrances

There are two entrances separated by about 45 minutes, so make sure to pick the right one!

The northern, Brentwood entrance provides access to the John Muir Interpretive center while the southern, Livermore, entrance provides access to the marina. The link on the map to the right will bring you to the south entrance. For a link to the northern entrance (and through to the interpretive center), click here.

From the Walnut Creek, Concord, and Antioch areas of the easy bay, the fastest way is probably via Highway 4 West to Vasco.

If coming from other parts of the bay area, take 580E and exit Vasco road in Livermore.
