With its rolling, grassy hills and secluded, shady canyons, Briones is a secret wilderness surrounded by the towns of central Contra Costa County. Although the park is close to Lafayette, Walnut Creek, Pleasant Hill, Concord, and Martinez, there are peaks within it from which you can see only park and watershed lands for miles in every direction. Briones is an ideal park for hiking, running, and horseback riding over the park’s scenic trails.

From Briones Peak, the highest point in the park, there are panoramic views of Mount Diablo and the Diablo Valley to the east, the Sacramento River and Delta to the north, the East Bay hills and Mt. Tamalpais to the west, and Las Trampas Regional Wilderness to the south. (

This hike starts at the Briones Regional Park Alhambra Creek Staging Area off of Reliez Valley Rd in Martinez. Begin the hike on the Alhambra Creek Trail, it starts out gradually and then becomes fairly steep. The shady trail winds through a wooded area of Briones to the Spengler Trail junction.
