The Santa Ynez Mountains are a portion of the Transverse Ranges, part of the Pacific Coast Ranges of the west coast of North America, and are one of the northernmost mountain ranges in Southern California.
They are principally in Santa Barbara County, with an eastward extension into Ventura County, and are unusual in being an entirely east-west trending mountain range-one of the few in the United States.
The mountains extend from an eastern terminus at the canyon of the Ventura River and Matilija Creek, north of Ojai, west across the Santa Barbara County line, to immediately north of the city of Santa Barbara, and then west, paralleling the coast, to the city of Lompoc and Vandenberg Air Force Base. The Santa Ynez River flows just north of the mountains, paralleling them for most of their length. Before reaching Lompoc the mountain range diverges into two low ranges, separated by Jalama Creek, which then vanish into the Pacific Ocean.
