TranslateOverview
Muir Woods National Monument is a federally protected forest in Marin County, California, roughly 12 miles north of San Francisco. It preserves one of the last significant stands of old-growth coast redwoods (Sequoia sempervirens) in the greater Bay Area, with some trees exceeding 250 feet in height and 1,000 years in age.
The monument sits within the Mount Tamalpais watershed in the Golden Gate National Recreation Area. Redwood Creek runs through the canyon floor, creating a cool, damp microclimate that nurtures the forest even during California's dry summers.
Named in honor of conservationist John Muir, the site was established as a national monument in 1908 by President Theodore Roosevelt. It is one of the most visited units in the National Park System and a meaningful destination for anyone interested in old-growth forest ecology, conservation history, or simply spending time in a quiet, ancient landscape.
Because of its popularity and the sensitivity of the ecosystem, the National Park Service has implemented a timed-entry reservation system for vehicle parking. Visiting without a car — via shuttle or other means — is strongly encouraged and may not require a reservation, but visitors should verify current requirements on the official NPS site before traveling.
Before You Go
Reservations and Entry
Muir Woods operates a parking reservation system that is typically required during peak seasons and weekends. Reservations can be made through the official Recreation.gov platform. Check the NPS Muir Woods page (nps.gov/muwo) for current reservation policies, fees, and hours before your visit, as these change seasonally.
What to Pack
- Layered clothing: the redwood canyon is noticeably cooler and more humid than surrounding hillsides, even on warm days
- Comfortable, closed-toe shoes with good grip — trails can be muddy or slippery
- Water and snacks; food options inside the monument are limited
- Rain gear is advisable in winter and spring
Accessibility
The main canyon floor boardwalk trail (approximately the first mile of the main trail system) is paved and relatively flat, making it accessible to visitors using wheelchairs or strollers. Steeper connector trails are unpaved and more demanding. Verify current accessibility conditions on the official NPS site.
Pets
Dogs and other pets are not permitted on trails within Muir Woods National Monument. Service animals are allowed in accordance with federal law.
Getting There
From San Francisco
Muir Woods is approximately 12 miles north of San Francisco via US-101 and Highway 1 or Muir Woods Road. The winding approach roads are narrow, and parking at the monument is limited and reservation-dependent. Driving from San Francisco takes roughly 30–45 minutes depending on traffic, but the final stretch of Muir Woods Road requires careful navigation.
Shuttle Service
The Marin Transit Muir Woods Shuttle (Route 66) has historically operated seasonally from the Sausalito Ferry Terminal and Marin City, providing a car-free option that avoids parking challenges. Check Marin Transit (marintransit.org) for current schedules, fares, and operating seasons, as service details change year to year.
Ferry + Shuttle Combination
Golden Gate Ferry or Blue & Gold Fleet ferries connect San Francisco's Ferry Building to Sausalito, from which the shuttle can be taken to the monument. This is a popular and practical car-free approach. Verify current ferry schedules and fares directly with the operators.
By Private Vehicle
If driving, book a parking reservation in advance through Recreation.gov. GPS navigation on Muir Woods Road can be unreliable in spots — download offline maps or follow posted road signage.
Getting Around
The monument's trail network is compact and manageable on foot. The Main Trail along the canyon floor is paved boardwalk for its initial stretch and is the most heavily trafficked route. A one-way loop combining the Main Trail and the Bohland Trail is a popular introduction to the forest.
Several unpaved connector trails lead uphill out of the redwood canyon and connect to the broader Mount Tamalpais State Park trail system. These include the Ben Johnson, Bootjack, and Dipsea trails, which offer more strenuous hiking and panoramic views. Hikers comfortable with elevation gain can create longer loops that exit or re-enter the monument at different points.
There is no motorized transport inside the monument. The trail system is entirely pedestrian. Trail maps are available at the visitor center entrance and on the NPS website.
Things to See & Do
Walking and Hiking
The forest itself is the primary attraction. Even a short walk along the Main Trail delivers the full sensory experience of an old-growth redwood grove — cathedral-like canopy, filtered light, and near-silence. Longer hikes connecting to Mount Tamalpais State Park expand the experience significantly.
- Main Trail / Cathedral Grove: Flat, accessible, and the heart of the monument. Cathedral Grove contains some of the tallest trees.
- Ben Johnson Trail: A steeper unpaved trail climbing out of the canyon through mixed woodland toward Mount Tamalpais.
- Dipsea Trail: A legendary long-distance trail connecting Mill Valley to Stinson Beach that passes through portions of Muir Woods. The full route is a significant undertaking.
Visitor Center and Exhibits
The visitor center near the entrance provides interpretive exhibits on redwood ecology, the history of the monument, and the life cycle of coast redwoods. Park rangers and volunteers are often available to answer questions.
Photography
The forest offers exceptional photographic conditions, particularly in the early morning when mist settles in the canyon and crowds are thinner. A wide-angle lens helps capture the scale of the trees.
Ranger Programs
The NPS occasionally offers ranger-led walks and talks. Check the NPS website or inquire at the visitor center for current programming.
Food & Drink
Food and beverage options inside Muir Woods are limited. A small café near the visitor center has historically offered basic hot drinks, snacks, and light fare, but offerings and operating hours vary — verify locally before relying on it for a meal.
Visitors are encouraged to bring their own water and snacks. Eating is not permitted on the boardwalk trails to protect the ecosystem; designated picnic areas are available near the entrance.
For fuller dining, the nearby town of Mill Valley (approximately 4 miles away) has a range of cafés, casual restaurants, and grocery options. Sausalito, about 8 miles away, offers waterfront dining with views of San Francisco Bay.
Practical Information
Admission
Muir Woods charges an entrance fee. Fees are subject to change; check nps.gov/muwo or Recreation.gov for current pricing. The America the Beautiful interagency annual pass covers entrance fees at Muir Woods and may be worthwhile for visitors planning to visit multiple federal lands.
Hours
The monument is open daily, but opening and closing times vary by season. Check the official NPS site for current hours before your visit.
Facilities
Restrooms are available at the main entrance area. The visitor center sells books, maps, and souvenirs. There are no ATMs inside the monument; card payment is standard at the entrance.
Cell Service
Cell phone reception is limited inside the canyon. Download trail maps and any needed information before arriving.
Leave No Trace
The NPS enforces strict guidelines to protect the ecosystem. Do not remove any natural materials, stay on designated trails, and carry out all trash. Disturbing or climbing on the trees is prohibited.
Safety
Muir Woods is a safe and well-managed site. The primary practical risks are minor:
- Trail hazards: Unpaved upper trails can be slippery, especially after rain. Wear appropriate footwear.
- Weather: The canyon is significantly cooler than nearby areas. Dress in layers even in summer.
- Wildlife: Black-tailed deer are common and generally non-threatening. Do not feed or approach wildlife. Mountain lions are present in the broader Mount Tamalpais area but encounters in Muir Woods itself are extremely rare.
- Getting lost on extended hikes: If continuing onto Mount Tamalpais trails, carry a downloaded map and adequate water, as trail junctions are numerous and cell service is unreliable.
For emergencies within the national monument, contact NPS rangers at the visitor center or call 911. The Golden Gate National Recreation Area dispatch can also be reached — verify the current non-emergency ranger contact number on the NPS site.
