Yes, this lighthouse at the southwest tip of the Marin Headlands is still active and maintained by the U.S. Coast Guard. Getting there is a challenge. Parking is limited and the 0.5-mile walk is steep and precarious. This spot, at the "world's end," is ruggedly beautiful. Nearby, old army buildings are used for environmental education programs.

Endlessly explore the vast wilds here, one of the most stunning oceanfront parks in the world. This 70,000-acre peninsula north of San Francisco stretches from the wild and wind-chilled great beaches on the northwest side (where Sir Francis Drake landed in 1567) across forested ridges to the south.

Visitors keep discovering new pleasures in this jewel of a national park. From eucalyptus-lined ridges overlooking the City to its restored wetlands and beaches, it is both a place of tranquil seclusion and unique activities. Transferred from the Army to the National Park Service in 1994, the Presidio offers forests and museums, rambling trails and restaurants, cliffside surf and historic architecture.

Ready for a challenge? This 4,000-acre park above the San Mateo coast is a former Spanish colonial land grant. It boasts miles of winding public trails, important watersheds, diverse wildlife, and, atop 2,000-foot Montara Mountain, a breath-taking 360-degree view from the Bay to the Pacific.

Imagine yourself on the coast of Scotland. At this glorious, rocky bluff off Highway 1 near Stinson Beach you can park and hike down to Red Rock Beach. The Pacific roars, winds stir the chaparral, and if you make reservations far in advance you can spend the night at rustic cabins here.

Windswept, exhilarating, and covered with unique red and green pebbles, this beach is just three miles northwest of the Golden Gate Bridge.

Rich with wildlife habitats, Rodeo Valley winds through the heart of the Marin Headlands and is edged by grassy, wind-swept hillsides. Where it descends to the Pacific, there is a lagoon and shallow wetlands home to shorebirds including egrets and ducks, as well as butterflies and occasional bobcats.

Amble along the alabaster sands here, one of the most perfect beaches on the California coast. Find it 35 minutes north of the Golden Gate Bridge via Highway 1, which unwinds atop heart-stopping cliffs. 

The fine ruins here excite visitors' imaginations. Adolf Sutro, a visionary 19th-century San Francisco mayor, built a home and gardens on a bluff overlooking the Pacific. Today all that is left are dreamily romantic gardens. Below it, on a rocky shore, are the vast remains of Sutro Baths.

Ridges and ravines mark this hiking area 25 minutes south of San Francisco. Wildlife, including hawks, deer, and wildflowers, abound on the slopes which drop to the Bay on one side and Thornton Beach on the other. The park's highest point is 1,200 feet and has a plaque honoring Portola's discovery of the Bay in 1769.
