Tennessee Valley is well known as one of Marin County’s most accessible and rewarding casual hikes. The main route—from the trailhead to Tennessee Beach—is ideal for those seeking a taste of rugged coastal scenery without much physical strain. However, the area also connects to a vast trail network, offering routes for more ambitious hikers. One such rewarding, though demanding, option is the round-trip hike from Tennessee Valley to the serene and secluded Muir Beach.
Reaching Muir Beach from Tennessee Valley requires crossing a steep ridge that marks the valley’s northern edge. While there are several trails that lead there, all involve significant elevation changes. The hike is strenuous, but the payoff is exceptional: Muir Beach is a quiet, storybook hamlet hidden just a few miles from Mill Valley and Stinson Beach, yet it feels worlds away from urban life.
It’s important to note that this hike is not dog-friendly. Even leashed dogs are prohibited on many of the trails in the region.
Trail Summary:
Begin your hike at the Tennessee Valley Trailhead, where parking is available at the end of Tennessee Valley Road. From the trailhead, walk about 0.3 miles until you reach the Fox Trail (just past the Haypress Campground trail). Follow the Fox Trail for 1.4 miles until it merges with the Coastal Trail. Stay on the Coastal Trail for another 1.6 miles to reach Muir Beach. For the return, you can retrace your steps or opt for a loop using the Pirates Cove Trail or the Middle Green Gulch Trail (approximately 2.4 miles) that reconnects with the Fox Trail. In total, expect a hike of at least 7 miles.
Trail Experience:
The Fox Trail is relatively quiet, even on busy weekends. In spring, wildflowers line the trail in vivid colors. During one recent hike, a tall blue heron stood silently near the trailhead, hunting in the underbrush. Hikers might also catch glimpses of California quail darting between bushes, or spot deer, turkeys, and even bobcats in the distance. Keep an eye out for rattlesnakes, especially in warmer months.
As you ascend the Fox Trail, ocean views begin to appear on the horizon. Eventually, the trail splits into the Coyote Ridge and Coastal trails. Follow the Coastal Trail, which descends steeply down the far side of the ridge. Because the descent is steep and gravel-strewn, be sure to wear shoes with good traction to avoid slipping. During this part of the hike, you’ll be treated to beautiful views of Muir Beach and its hillside homes sparkling in the sun.
At the bottom, the trail intersects with a path leading to Muir Beach on the left and the historic Pelican Inn on the right. The inn offers food and drinks, making it a great spot for a traditional English-style pub meal after your hike. If you plan your visit for May 25, you’ll catch the Muir Beach Volunteer Firemen’s Barbecue—a fun, festive community event with more food and local charm.
Return Route Options:
There are several options for completing the return to Tennessee Valley. One is to simply retrace your route, possibly taking the Pirates Cove Trail for a change of scenery. This alternate trail also leads back toward Tennessee Valley.
Another appealing route involves a loop via the Green Gulch Farm Zen Center. This trailhead sits across from the Pelican Inn and leads to the Zen Center, about half a mile away. The trail passes through farm pastures and tranquil gardens. Visitors are welcome to walk through, but should take care to close all gates to prevent deer and other wildlife from entering the cultivated areas. You may see horses along this part of the route—either grazing in pastures or sharing the trail.
From the Zen Center, the Middle Green Gulch Trail takes hikers through lush vegetation and shaded woodlands. It connects with the Coyote Ridge Trail, which leads back to the Fox Trail. A short descent from there will bring you back to the Tennessee Valley trailhead, completing the loop.
This hike is ideal for those seeking a challenge and a change of pace from the more frequented routes in Marin. With its mix of coastal views, wildlife, hidden communities, and varied landscapes, the Tennessee Valley to Muir Beach trek offers an unforgettable day outdoors.
