Manchester State Park has 760 acres of beach, dunes and flat grasslands. Five miles of gentle, sandy beach stretches southward towards the Point Arena Lighthouse. One of the main attractions is the excellent steelhead and salmon fishing in the park's two streams, Brush Creek and Alder Creek. The park features a variety of coastal wildflowers, including sea pinks, poppies, lupines, baby blue eyes and blue irises. The park provides habitat for tundra swans. The San Andreas Fault runs into the sea at the park.
