Before slipping into the sea, the northernmost segment of the San Andreas Fault cuts through this park beloved by locals for its 5 miles of sandy, usually empty shoreline and trails that wind through dunes and wetlands. Hiking, bird-watching, and beach strolling are the popular activities here. There's steelhead fishing most of the year at Brush and Alder creeks, and beautiful coastal wildflowers bloom in early spring. Tundra swans overwinter in this area, and migrating whales are often spotted close to shore. Swimming and water sports are too dangerous because of the strong undertow. Dogs are not allowed on the beach. Amenities: parking. Best for: solitude; sunset; walking.
