Marin County has been called the San Francisco Bay Area’s park. Almost 85 percent of its land has been protected from development through open space purchases, federal parkland, watershed lands and strict agricultural zoning.

The spectacular Point Reyes National Seashore and the Golden Gate National Recreation Area have been set aside for the enjoyment and use of the public. More than 2.5 million people travel to Marin each year to enjoy the beaches and unspoiled wilderness that make up the Point Reyes National Seashore.

They are joined by hundreds of thousands of national and international visitors who stroll through Muir Woods and marvel at this towering ancient redwood forest. The scenery and beauty of Marin County’s environment is an unusual treasure.
