TranslateOverview
Muir Woods National Monument preserves one of the last remaining old-growth coast redwood (Sequoia sempervirens) forests in the San Francisco Bay Area. Located in Mill Valley within Marin County, the monument covers roughly 554 acres and sits in a sheltered canyon carved by Redwood Creek, where marine fog and the steep terrain have protected the trees from logging for centuries.
The monument was established in 1908 under President Theodore Roosevelt and named after conservationist John Muir. Today it is administered by the National Park Service as part of the Golden Gate National Recreation Area, drawing well over a million visitors each year.
The forest floor is quiet, shaded, and cool even in summer. Cathedral Grove — where the oldest and tallest trees stand — frequently inspires comparisons to the interior of a vast natural cathedral. The main loop trails along Redwood Creek are flat and accessible, while connecting trails climb steeply into surrounding Mount Tamalpais State Park for those seeking a longer hike.
Before You Go
Reservations Are Essential
Muir Woods operates a timed-entry reservation system for both parking and shuttle access during peak periods. Walk-in access without a reservation is generally not guaranteed. Check the official National Park Service website (nps.gov/muwo) well in advance to book your entry and, if needed, a parking pass. Reservation windows typically open weeks ahead; popular weekend slots sell out quickly.
Admission
Muir Woods charges an entrance fee. Children under a certain age enter free. The America the Beautiful annual pass (Interagency Annual Pass) is accepted. Verify current fee amounts on the NPS website before your visit, as prices are updated periodically.
What to Bring
- Layers: the canyon is noticeably cooler than surrounding areas year-round
- Comfortable, closed-toe walking shoes — trails can be damp and slippery
- Water and snacks; food options inside the monument are limited
- Cash or card for the gift shop/café
- A camera — flash photography is not necessary and tripods may require a permit
Pets and Rules
Pets are not permitted on any trails within Muir Woods. Leave No Trace principles apply strictly: do not remove any natural materials, feed wildlife, or stray off marked paths.
Getting There
By Shuttle (Recommended)
The Marin Transit Muir Woods Shuttle (Route 66F) runs seasonally from the Sausalito Ferry Terminal and Marin City Hub. This is the most stress-free option and pairs well with a ferry crossing from San Francisco's Ferry Building. Verify the current schedule and operating season with Marin Transit (marintransit.org), as service dates and frequency change year to year.
By Car
Muir Woods is located off Muir Woods Road, accessed via Highway 1 or the Panoramic Highway from Highway 101. The access roads are narrow and winding; large RVs and trailers are discouraged. A timed parking reservation is required during peak periods — check nps.gov/muwo before driving. GPS navigation is reliable for the final approach, though cell signal can drop along the canyon road.
By Ferry + Shuttle
The Golden Gate Ferry and Blue & Gold Fleet both serve Sausalito from San Francisco. From Sausalito, the seasonal shuttle provides onward connection. This combination is popular and helps reduce road congestion; confirm current schedules locally or on respective ferry operator websites.
From San Francisco
The monument is approximately 12 miles north of San Francisco via the Golden Gate Bridge, though the winding final miles mean driving time is typically 45 minutes to over an hour depending on traffic.
Getting Around
Muir Woods has a well-marked trail network within the monument itself. The main Redwood Creek Trail is a paved, relatively flat loop suitable for most visitors, including those with strollers (though the path narrows in sections). Boardwalks protect sensitive root systems along much of the valley floor.
Connecting trails — including the Dipsea Trail and Ben Johnson Trail — lead uphill into Mount Tamalpais State Park. These are unpaved, steeper, and best suited to hikers with appropriate footwear. Trail maps are available at the entrance kiosk and downloadable from the NPS website. Cell service is unreliable inside the canyon, so download or print a map before arrival.
Things to See & Do
Walk Among the Redwoods
The primary draw is simply walking the trail network beneath trees that can exceed 250 feet in height and 1,000 years in age. Cathedral Grove, accessible from the main loop, contains some of the oldest specimens. Interpretive signs along the trail explain redwood ecology, the role of fog in tree survival, and local natural history.
Birdwatching
The forest supports varied birdlife including Steller's jays, Pacific wrens, spotted owls (rarely seen), and various warblers and woodpeckers. The creek corridor attracts waterfowl and the American dipper. Dawn visits — when crowds are thinnest — offer the best chance of quiet wildlife observation.
Photography
The interplay of filtered light and dense canopy makes for rewarding photography throughout the day. Morning and late afternoon light filtering down from the ridge provides the most dramatic effects. Keep expectations in check on overcast days — the diffuse fog light is actually ideal for even, shadow-free forest shots.
Extend into Mount Tamalpais State Park
Several trails depart Muir Woods and climb into adjacent Mount Tamalpais State Park, offering panoramic Bay Area views from higher elevations. The Dipsea Trail is a historic route connecting the forest to Stinson Beach. Plan extra time and fitness for any out-and-back hike on these steeper connecting paths.
Food & Drink
A small café operates at the visitor center near the main entrance, typically offering coffee, beverages, and light food items. Seating is limited. Hours and menu availability vary by season — verify locally on arrival.
There are no restaurants within the monument itself. Most visitors bring their own food. Eating on the trails is permitted but pack out all waste. For a full meal, nearby Mill Valley (approximately 4 miles away) has a well-regarded restaurant and café scene worth exploring before or after your visit.
Practical Information
Facilities
The visitor center near the main entrance provides restrooms, interpretive exhibits, a gift shop, and the café. There are no restrooms along the trail network itself, so plan accordingly before setting out.
Accessibility
The main valley floor boardwalk and paved sections of the Redwood Creek Trail are accessible to most visitors, including wheelchair users for much of their length. The National Park Service website provides current accessibility details including surface conditions.
Weather and Clothing
Even on warm Bay Area days, the canyon interior is cool and often damp. Temperatures can be 10–15°F lower than in San Francisco. Bring a layer regardless of the season. Fog is common, particularly in summer mornings.
Emergency Contact
For emergencies inside the monument, contact National Park Service rangers via the visitor center or dial 911. Cell coverage is limited in the canyon — note the location of the visitor center upon arrival.
Visas
For entry requirements into the United States, visit TravelerPulse's Visas section and consult the U.S. Department of State (travel.state.gov) or your nearest U.S. embassy or consulate. Requirements vary significantly by nationality.
Safety
Muir Woods is a safe, well-managed site. The main risks are environmental rather than security-related.
- Slippery trails: Damp redwood duff and boardwalks can be slippery; tread carefully, especially in wet weather
- Wildlife: Black-tailed deer are common and generally unafraid of humans — do not approach or feed them; mountain lions are present in the broader Marin landscape but extremely rarely encountered
- Getting lost on connecting trails: Trails into Mount Tamalpais State Park are poorly marked compared to the main loop; download a map and note the time before departing
- Hypothermia risk: Unlikely for most visitors on the main loop, but hikers going higher on connecting trails in fog and wind should have sufficient layers
- Leave the forest as you found it: Removing rocks, plants, or other natural material is illegal and subject to fines
