Muir Woods National Monument, managed by the National Park Service, preserves one of the last remaining ancient old-growth coast redwood forests in the San Francisco Bay Area. Established in 1908, it protects 554 acres of towering redwoods, some over 1,000 years old and reaching heights of 250 feet. The monument is part of the Golden Gate National Recreation Area and offers hiking trails for visitors to experience this natural cathedral. It serves as a refuge and a living laboratory, showcasing the relationship between humans and the natural landscape, and is home to diverse plant and animal species, including Coho salmon and steelhead trout in Redwood Creek.
