Blue Canyon gets its name from the blue-green serpentine formations found along its 5 mile length. The canyon runs directly along the Santa Ynez Fault. This is a relatively narrow canyon with several overnight camps along it and a stream that flows year round. Beyond Cottam Camp a number of options are available. You can walk to the car camps at P-Bar Flats and Mid-Santa Ynez, continue down the Santa Ynez River to the Mono Trail and Mono Debris Dam, or make your way up to Forbush Flat.
