Moderate temperatures help make Emma Wood State Beach popular for swimming, surfing and fishing. Catches include perch, bass, cabezon and corbina. The Ventura River estuary is at the mouth of the Ventura River at the southeast end of the park. It attracts a variety of wildlife including raccoons, songbirds and great blue herons. Dolphins are occasionally seen just offshore. The park also features the crumbling ruins of a World War II coastal artillery site. The offshore Channel Islands can be seen from the beach.
