Big Break Regional Shoreline is a regional park in Oakley, Contra Costa County, northern California. It is a part of the East Bay Regional Park District system.

Delta Visitor Center

The park features an $11 million, 5,000-square-foot Delta Visitor Center, which operates as a natural history museum, science laboratory, and staging area for paddling and hiking trips along the Sacramento–San Joaquin River Delta. The new visitor center opened in October 2012.

The center includes a 1,200 square feet (110 m²) interactive map of the Sacramento–San Joaquin River Delta that shows visitors how water flows through the region. A 30-by-50 model of the delta is also located at the park, as well as restored wetlands.^[1]

Park name

The park is named for a break in the levee system that flooded an asparagus farm between the San Joaquin River and Dutch Slough in 1928.^[2] The break formed a small bay along the river, near the area where fresh water from the river mixes with salt water from San Francisco Bay.^[3]
