The San Benito River is a river on the Central Coast of California. From its headwaters southeast of Santa Rita Peak in the Diablo Range, it flows northwest between the Diablo Range and the Gabilan Range, traveling for about 109 miles (175 km)[3], past Hollister, California, where it turns east into the San Juan Valley where it follows the northern hills before turning north to its confluence with the Pajaro River, about 15 miles (24 km) upstream from the river's outlet in Monterey Bay. The San Benito River is longer than the Pajaro River and it drains more area, but it has proportionally lower flows. The streambed is usually dry during the summer, as the Central Coast receives almost all of its rain during the winter.
The surrounding mineral soils come from serpentine which has naturally occurring asbestos. Mining of asbestos, sand, gravel and gypsum have somewhat degraded the watershed. Benitoite was first discovered in the headwaters of the river and is named after it. There are no major dams on the San Benito River.
