"Arguably the premier complex of public lands in this part of the East Bay, the adjoining Anthony Chabot and Lake Chabot parks see plenty of use. This loop takes you into a more remote part of Anthony Chabot Regional Park, where you’ll enjoy a gentle tour of the rangeland and woodlands along Grass Valley Creek. Oh, Chabot. So much to do, so much to see. You can hike, swim, fish, camp, shoot, golf, and take boat tours. But ultimately, you can hike. The Grass Valley and Brandon Trails are part of Anthony Chabot Regional Park, which abuts Lake Chabot Regional Park. Both parks are named for Anthony Chabot, an enterprising nineteenth-century businessman who, among other endeavors, built the dam that created the Lake Chabot reservoir in the 1870s. Portions of the parks were also, at one time, part of the colonial rancho system. The trails travel through a shallow valley far removed from development and activity around Lake Chabot."
