Part of the spectacular Guadalupe-Nipomo Dunes this 3,600-acre coastal playground is one of the few places in California where you can drive or ride off-highway vehicles on the beach and sand dunes. Hike, ride horses, kiteboard, join a Hummer tour, or rent an ATV or a dune buggy and cruise up the white-sand peaks for spectacular views. At Oso Flaco Lake Nature Area —3 miles west of Highway 1 on Oso Flaco Road—a 1½-mile boardwalk over the lake leads to a platform with views up and down the coast. Leashed dogs are allowed in much of the park except Oso Flaco and Pismo Dunes Natural Reserve. Amenities: food and drink; lifeguards (seasonal); parking (fee); showers; toilets; water sports. Best for: sunset; surfing; swimming; walking.
