Insects of Briones Regional Park - East Bay Regional Park District  

"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. 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.." - EBRPD
