Gaviota Tunnel

The Gaviota Tunnel (officially known as the Gaviota Gorge Tunnel) is a tunnel completed in 1953 north of Gaviota State Park, 33 miles (53 km) northwest of Santa Barbara, and it is on U.S. Highway 101. It is 128 feet (39 m) long and its elevation is 14 feet, 9 inches (4.4 m). Only the northbound lanes of U.S. Highway 101 (El Camino Real) pass through it, as the southbound lanes descend from Gaviota Pass through a narrow canyon to the west of the tunnel. Because it is the only major route between the Santa Barbara County South Coast and the Santa Ynez Valley, bicycles are allowed through it.

There is a rest area on the southern end of the tunnel, the southernmost one along U.S. Highway 101.
