It is awesome atop this 2,500-foot high mountain in Marin with its 360-degree view from San Francisco Bay to the Pacific. But anywhere on "Tam" you can find nature at its most glorious. Miles and miles of trails ribbon the mountain, crossing redwood valleys, creeks, waterfalls, and wide-open grasslands. It has been treasured turf for hikers, cyclists, and equestrians since the 1880s.

See a verdant redwood forest reborn here at the southern tip of the Golden Gate National Parks. This tranquil park was once severely logged and century-old redwood stumps and remnants of steam mills are still in evidence.

At every turn of the trail on this wild and rocky northwestern corner of San Francisco, there is another stunning vista. Along the way you'll see hillsides of cypress and wildflowers, views of old shipwrecks, access to the epic ruins of Sutro Baths, pocket beaches, and a new Lookout Visitor Center. You can thank community volunteers who have helped revitalize and restore the native habitat here.

On a clear day you can see as far as Point Reyes from this park adjacent to the Marin Headlands. Trails loop through groves of eucalyptus and bay laurel. In the spring you will find lupine and California poppies. In summer, the grasses turn golden, and by late summer you can find fennel, sagebrush, and blackberry bushes.

People do not just visit Muir Woods. They come from around the globe to pay homage to nature in this cathedral of redwoods. The trees' ages range from 400 to 800 years, their height up to 250 feet. Flat easy trails loop through the groves and across creeks. Parking can be an issue.

You are likely to award this National Historic Site as having the most astonishing view of the Golden Gate Bridge. A Civil War-era brick fort, it lies directly below the southern end of the span. Check for tours, especially candlelight evening ones, and annual Civil War reenactments. Interestingly, no military action ever occurred here.

Attention, hikers. This wide-open valley through the rolling Marin Headlands is ALL views. Its five-mile loop connects to a network of other trails that rise and fall gently through grassland and coastal chaparral. Hikers, cyclists, and equestrians share Gerbode Valley.
