Overview
Muir Woods National Monument protects roughly 560 acres of old-growth coastal redwood forest in Marin County, about 12 miles north of San Francisco. The monument was established in 1908 and named after naturalist John Muir. Its canyon location, sheltered by Mount Tamalpais, creates the cool, moist microclimate that allows coast redwoods (Sequoia sempervirens) to thrive at this latitude.
The tallest trees in the park exceed 250 feet in height, and some are estimated to be more than 1,000 years old. Redwood Creek runs through the main canyon, providing critical habitat for coho salmon and steelhead trout. The forest floor is dense with ferns, sorrel, and mosses, giving the monument a primeval atmosphere that is relatively rare this close to a major metropolitan area.
Because Muir Woods receives well over a million visitors per year, the National Park Service requires advance reservations for parking and shuttle access during busy periods. First-time visitors are often surprised by how quickly the forest transitions from crowded boardwalk to quiet backcountry trail within a short walk.
Before You Go
Reservations
Parking at the Muir Woods lot, as well as seats on the Muir Woods Shuttle from Sausalito and Marin City, typically requires advance reservation through the official Recreation.gov system, especially on weekends and holidays from roughly late February through November. Verify current reservation requirements on the official National Park Service (NPS) site before your trip, as policies can change seasonally.
Admission
There is an entrance fee for visitors 16 and older. The America the Beautiful annual pass (Interagency Pass) covers admission. Verify current fee amounts at nps.gov/muwo or Recreation.gov before visiting.
What to Bring
- Layers: The canyon is noticeably cooler and damper than surrounding areas, even on warm days.
- Sturdy footwear: Paved boardwalks give way to unpaved, sometimes muddy, backcountry trails.
- Water and snacks: There is a small café near the visitor center, but options are limited.
- No pets: Dogs are not permitted anywhere in Muir Woods.
- No drones: Unmanned aircraft are prohibited within the monument.
Getting There
By Shuttle (Recommended)
The Muir Woods Shuttle operates from Sausalito Ferry Terminal and Marin City Hub on a seasonal schedule. Seats must be reserved in advance through Recreation.gov. This is the most stress-free option, particularly on weekends. Verify current schedules and pricing on the official shuttle booking page before travel.
By Car
Muir Woods is reached via Highway 1 or Highway 101 north of San Francisco, then through Marin County's winding roads (primarily Muir Woods Road). Navigation apps handle the route well, but the final approach roads are narrow and steep — avoid large RVs or trailers. A parking reservation is required during busy periods; without one, you may be turned away at the gate.
From San Francisco
Visitors commonly take the Golden Gate Ferry or Blue & Gold Fleet ferry to Sausalito and then board the shuttle. This eliminates driving entirely and is a scenic approach. Ferry schedules and fares should be confirmed with the ferry operators directly, as they change seasonally.
By Bicycle
Cyclists may enter without a reservation and can access the monument via the Marin County trail network, including the Dipsea Trail and roads through Mill Valley. This is a hilly, moderately demanding ride and best suited to experienced cyclists.
Getting Around
The main valley floor is covered by a paved and boardwalk trail system that is accessible to most visitors, including those with mobility limitations (verify current accessibility conditions with the park). This main loop is approximately 2 miles and takes 45–90 minutes at a leisurely pace.
Beyond the main boardwalk, unpaved backcountry trails connect Muir Woods to Mount Tamalpais State Park. Trails such as the Dipsea, Ben Johnson, and Bootjack offer longer hikes with significant elevation gain. Trail maps are available at the visitor center; download one in advance from nps.gov/muwo as cell service inside the canyon can be unreliable.
There is no internal vehicle transport. Everything within the monument is on foot. Trail closures can occur after heavy rain due to mud and erosion — check the NPS site for current conditions.
Things to See & Do
Walking the Main Loop
The Cathedral Grove and Bohemian Grove sections of the main trail are where the largest, oldest redwoods stand. Interpretive signs identify individual trees and explain redwood ecology. Early morning visits offer the best light filtering through the canopy and the fewest crowds.
Backcountry Hiking
The Ben Johnson Trail and Bootjack Trail climb steeply out of the canyon into Mount Tamalpais State Park, rewarding hikers with ridge views and quieter forest. The Dipsea Trail, one of California's most historic footpaths, passes through the monument and continues to the coast at Stinson Beach — a full one-way route of roughly 7 miles from Mill Valley.
Wildlife and Nature Observation
Coho salmon and steelhead trout runs in Redwood Creek are typically visible from bridges in winter months (timing varies by rainfall and conditions). Banana slugs, Steller's jays, and varied thrush are commonly seen. Northern spotted owls inhabit the area but are elusive.
Ranger Programs
The NPS periodically offers ranger-led walks and educational programs. Check the current schedule at nps.gov/muwo. The visitor center includes exhibits on redwood ecology and the history of the monument's conservation.
Food & Drink
There is a small café operated near the main entrance that offers coffee, snacks, and light meals. Hours and menu offerings should be verified locally, as they are subject to change. Food and drink options are limited, and outside food is generally permitted on the trails — carrying your own lunch is a practical choice for hikers planning a full day.
The nearest broader dining options are in the town of Mill Valley (approximately 4 miles away), which has a good selection of cafes, bakeries, and restaurants. Sausalito, a short drive or ferry ride from San Francisco, also has waterfront dining options convenient if you are arriving via ferry and shuttle.
Practical Information
Cell Service
Expect limited or no cell service inside the main canyon. Download trail maps, your shuttle confirmation, and any other necessary information before arriving.
Accessibility
The main paved boardwalk loop is generally navigable by wheelchair users, though some sections can be uneven or have gentle grades. The visitor center is accessible. Contact the park directly via nps.gov/muwo to confirm current accessibility conditions before your visit.
Weather
The canyon is sheltered and typically 5–10°F cooler than downtown San Francisco. Fog and drizzle are common, even when it is sunny in the city. Waterproof layers are advisable year-round. Most rainfall occurs November through March.
Leave No Trace
Picking plants, disturbing wildlife, feeding animals, and removing any natural material (including fallen wood) is prohibited. Stay on designated trails to protect fragile root systems and forest floor organisms.
Emergency Contact
For emergencies within the monument, contact National Park Service rangers. The general NPS emergency line and Marin County Sheriff information can be found on nps.gov/muwo. In a life-threatening emergency, call 911.
Safety
Muir Woods is a low-risk destination for most visitors. The primary concerns are:
- Trail hazards: Backcountry trails can be slippery after rain and involve significant elevation change. Wear appropriate footwear.
- Getting lost: Cell service is unreliable. Download offline maps and inform someone of your hiking plans if venturing beyond the main loop.
- Poison oak: Present along many backcountry trails. Learn to identify it — three shiny leaflets — and stay on marked paths.
- Wildlife: Encounters with mountain lions are rare but possible on backcountry trails in and around Mount Tamalpais. NPS publishes standard guidance on what to do in the unlikely event of an encounter.
- Parking and road safety: The access roads are narrow and winding. Drive carefully and do not stop in the road for photos.
