Sun, Redwood, Panoramic, Lost and Fern Creek Loop

The loop can be accessed from various points, but a common starting point is from parking areas along Panoramic Highway. This approach allows you to experience the redwood groves of Muir Woods National Monument without needing an advance reservation for parking or paying the main entrance fee.

This route is rated as moderate. While it offers incredible scenery, it involves significant elevation changes, including a serious and steep climb with numerous wooden stairs on the Lost Trail segment. The Sun Trail also has narrow sections with steep drop-offs. Hikers should be prepared for varied terrain and a good workout.

The terrain is quite diverse. You'll encounter wide, flat boardwalks and trails along Redwood Creek Trail, steep climbs with wooden stairs, narrow and somewhat rough paths with steep drop-offs, and gradual rises on single-track trails. It transitions from dense redwood forests to more open landscapes.

You'll experience towering old-growth redwoods, especially in areas like the Cathedral Grove of Giant Redwoods. The Fern Creek Trail is abundant with various fern species. Higher sections, particularly along the Sun and Panoramic Trails, offer expansive views of Muir Woods, Mount Tamalpais, and surrounding hills.

Yes, this loop cleverly links together multiple distinct trails. You'll hike sections of the Sun Trail, Redwood Trail, Panoramic Trail, Lost Trail, and Fern Creek Trail. It also incorporates parts of the Canopy View Trail and the Dipsea Trail.

The trail is enjoyable year-round, but spring is particularly beautiful when the hillsides are dotted with wildflowers like poppies and lupine. The redwood groves offer cool shade in summer, and the varied ecosystems provide unique beauty in every season.

Dogs are generally not permitted on the trails within Muir Woods National Monument, which this loop traverses. Within Mount Tamalpais State Park, dogs are allowed on leash on fire roads and paved roads, but typically not on most single-track hiking trails. It's best to leave your furry friends at home for this particular adventure.

If you start from parking areas along Panoramic Highway, you can often avoid the entrance fee and reservation requirements associated with the main Muir Woods National Monument entrance. However, always check current regulations for Mount Tamalpais State Park, as conditions can change.

Beyond the iconic redwoods and abundant ferns, you'll pass through areas with bay and oak trees. In spring, look for wildflowers such as poppies and lupine. Keep an eye out for common forest wildlife like deer, various bird species, and smaller mammals.

Given the moderate difficulty and varied terrain, sturdy hiking shoes with good grip are essential. Bring plenty of water, snacks, layers of clothing for changing weather conditions, sun protection (hat, sunscreen), and a map or GPS device. Trekking poles can be helpful for the steep sections.

To minimize crowds, especially in the Muir Woods sections, consider starting your hike early in the morning or later in the afternoon. Weekdays are generally less busy than weekends. As mentioned, starting from parking along Panoramic Highway can also help bypass the main Muir Woods entrance crowds.
