Muir Woods National Monument is part of California’s Golden Gate National Recreation Area, north of San Francisco. It’s known for its towering old-growth redwood trees. Trails wind among the trees to Cathedral Grove and Bohemian Grove, and along Redwood Creek. The Ben Johnson and Dipsea trails climb a hillside for views of the treetops, the Pacific Ocean and Mount Tamalpais in adjacent Mount Tamalpais State Park.The average age of the coastal redwoods at Muir Woods is between 600 to 800 years, with the oldest being at least 1200 years old.Our guests share a light moment with this photo on their hike to Muir Woods.
