Muir Woods National Monument, nestled in Marin County, California, shelters towering old-growth coast redwoods, fern-lined creek trails, and a rare pocket of primeval forest just north of San Francisco.
Muir Woods National Monument was established in 1908, when President Theodore Roosevelt accepted William Kent's donation of the land and named it in honor of naturalist John Muir, whose advocacy for wild places shaped American conservation. The monument protects one of the few remaining stands of old-growth coast redwoods, Sequoia sempervirens, in the greater San Francisco Bay Area, with trees reaching heights of over two hundred feet and living for upward of a thousand years.
The main valley trail follows Redwood Creek on a mostly flat, paved path accessible to a wide range of visitors, while branching routes climb into the surrounding Marin Municipal Water District lands and connect to Mount Tamalpais State Park, opening up miles of additional hiking. Interpretive signs along the boardwalk explain redwood ecology, the role of coastal fog in sustaining the forest, and the monument's history within the Golden Gate National Recreation Area. Wildlife is present but quiet, including Steller's jays, banana slugs, and the occasional black-tailed deer moving through the understory.
There are no restaurants inside the monument, though a small visitor center offers basic refreshments and a well-stocked bookshop focused on natural history. The nearby town of Mill Valley provides cafes and dining a short drive away. Muir Woods National Monument stands as one of the most accessible old-growth forests in the United States, making it a genuinely irreplaceable place to understand what the California coast looked like long before European settlement.
Reserve your parking or shuttle pass well in advance, as the reservation system is required for most visitors and fills quickly, especially on weekends and holidays.
Visit during a weekday morning in the off-season, from November through February, when crowds are thinnest and the forest feels most serene.
Bring a waterproof layer year-round, as the canyon holds moisture and morning fog can keep temperatures cool and trails damp even in summer.
Walk the Hillside Trail loop above the valley floor for elevated views through the redwood canopy that most visitors following the main boardwalk never see.
Stay quiet near Redwood Creek in late fall and winter, when coho salmon return to spawn and can occasionally be spotted in the shallower stretches of the stream.
