Mendocino Headlands State Park is a California State Park in Mendocino, California. It consists of 347 acres (1.4 km2) of undeveloped seaside bluffs and islets surrounding the town of Mendocino, two beaches (Big River Beach and Portuguese Beach), and the much larger Big River Unit stretching for eight miles (13 km) along both banks of the nearby Big River.
The park began operation in 1974, after several years of concern and discussion from citizens about the possibility of blufftop development. The Big River Unit was added in 2002.
