Gaviota State Park is a state park of California, USA. It is located in southern Santa Barbara County, California, about 33 miles (53 km) west of the city of Santa Barbara. It extends from the Pacific coast to the crest of the Santa Ynez Mountains, and is adjacent to Los Padres National Forest. The 2,787-acre (1,128 ha) park was established in 1953.
The park is bisected by U.S. Route 101, which turns north from the coast at Gaviota, passing through the Gaviota Tunnel and Gaviota Pass, which is actually a deep canyon cut entirely through the southern branch of the Santa Ynez Mountains. Gaviota State Park consists of two units, one on each side of the highway. The western unit includes the beach and associated campground, which receives most of the park's visitors.
Both sections of the park contain trails for hiking, horseback riding, and mountain biking. The most heavily traveled trail is a short dirt road leading to a popular hot spring on the eastern side of the highway. A more substantial trail beginning at the same trailhead leads out of the park to the summit of Gaviota Peak, the highest mountain in the vicinity at 2,458 feet (749 m). While not exceptionally high, because it is an isolated peak the views are expansive in all directions; on a clear day it is possible to see much of Santa Barbara County, as well as the coast as far south as the Santa Monica Mountains. Trails within the park total 34 miles in all.
Plant communities in the park include chaparral in the upland regions, oak woodlands elsewhere, and both native prairie and non-native grasslands. They are part of the California coastal sage and chaparral ecoregion. The portion of Gaviota Creek that passes through the park includes one of the highest quality riparian habitats remaining in southern Santa Barbara County, and it receives strict environmental protection.
Much of the park vegetation was burned in a large brushfire in June 2004, with wildfire being a natural part of the chaparral ecosystem.
Adjacent to the park on the west is a large region of private ranches and ranchettes known as Hollister Ranch, which extends for almost the entire distance to Point Conception (where the California coast turns to the north). Access to this portion of the coast is tightly secured, and possible only by water for non-residents. Singer Jackson Browne owns a ranch adjacent to the park on the west.
The park includes a beach campground, which contains 39 campsites for RVs (up to 25 feet for most sites) and for tents. Additionally there are eight picnic sites. The park also includes a fishing pier which includes a small boat hoist; also nearby are some favorite surfing locations. There are no hook-ups or dump station.
The park is subject to a Mediterranean climate, with mild, rainy winters, and sunny summers, commonly with morning clouds. Temperatures below freezing are rare, and summertime high temperatures rise with increasing distance from the coast. Because of the topographical peculiarity of the region, a single deep canyon cut through the mountains, at certain times of year, most frequently in late spring, winds blow through the canyon with great force. These winds, known as Sundowners, are common all along the south coast of Santa Barbara County, but are frequently most violent in the Gaviota area.
