Route 24—Alameda County Scenic Byway gets its name from its surroundings, "alameda" meaning "the place where trees grow." Amongst an intensely urban area of California, this drive offers a rare escape into the trees and surrounding hills.
Route 24—Alameda County Scenic Byway travels entirely on HWY 24 from the east portal of the Caldecott Tunnel, past Orinda and Lafayette, to the junction of HWY 680 and the end of the byway.
Mt. Diablo, 3,849 feet, is a major focal point and great for recreation.
