Mount Tamalpais State Park

Mount Tamalpais State Park

Mill Valley, California (Marin County)

4.8 (3,088 reviews)

Mount Tamalpais State Park rises dramatically from the Marin County coastline just north of San Francisco, offering 6,243 acres of fog-swept ridges, old-growth redwood groves, and panoramic views that stretch from the Farallon Islands to the Sierra Nevada on clear days.

The park’s crown jewel is the 2,571-foot East Peak, accessible by car or foot, where visitors can see the curve of the Earth and watch fog pour through the Golden Gate like a slow-motion river. The Mountain Theater, a natural stone amphitheater built by the Civilian Conservation Corps in the 1930s, hosts performances against a backdrop of oak woodlands and distant bay waters.

Hikers have access to over 60 miles of trails ranging from gentle creekside walks through Muir Woods’ neighboring redwoods to strenuous climbs up the Steep Ravine Trail, which descends through waterfalls and fern-draped canyons to the Pacific. Mountain biking is popular on fire roads, and the park connects to a broader network spanning much of Marin’s open space.

The microclimate varies dramatically with elevation—coastal areas stay cool and foggy while the summit bakes in sunshine. Spring wildflowers blanket the grasslands from March through May, making it the most photogenic season. Summer mornings often start foggy before burning off by midday. Fall offers the clearest views and warmest temperatures.

With a 4.8-star rating from over 3,000 visitors, Mount Tamalpais consistently delivers one of the Bay Area’s most rewarding outdoor experiences.
