Muir Woods National Monument

Muir Woods National Monument is a remarkable preserve of old-growth coastal redwoods located in Marin County, California, just north of San Francisco. It is part of the Golden Gate National Recreation Area and is managed by the National Park Service. Named after John Muir, the famous naturalist and conservationist, Muir Woods is known for its towering ancient trees, tranquil atmosphere, and accessible walking trails that allow visitors to immerse themselves in a primeval redwood forest.


Muir Woods was established on January 9, 1908, when President Theodore Roosevelt signed legislation to protect an old-growth coast redwood forest from destruction. The land was donated by William Kent, a conservationist, and his wife, Elizabeth Thacher Kent, and they named it after John Muir because of his strong advocacy for wilderness preservation. Muir himself described the forest as “the best tree-lovers monument that could possibly be found in all the forests of the world.”


  • Muir Woods is home to coast redwoods (Sequoia sempervirens), some of the oldest and tallest trees on Earth.
  • The tallest tree in the Muir Woods reaches 258 feet, and the oldest trees in the park are estimated to be between 600 to 800 years old.
  • The monument covers 554 acres, with 240 acres of old-growth redwood forests.
  • Due to its proximity to the Pacific Ocean, the forest is regularly enshrouded in coastal fog, which helps sustain the trees during the dry summer months.
  • Muir Woods is an important habitat for numerous species, including the coho salmon, northern spotted owl, and various other plants and animals.


Muir Woods National Monument is located at 1 Muir Woods Rd, Mill Valley, CA 94941. It is situated 12 miles north of the Golden Gate Bridge, making it an easy day trip from San Francisco.

Muir Woods is open 365 days a year. However, hours vary by season, and it generally opens at 8:00 AM and closes around sunset. For the most accurate and up-to-date information on opening hours, it is best to refer to the National Park Service’s official Muir Woods website.
