Step into a serene world of ancient trees on the Roy's Redwoods Loop Trail, where towering old-growth redwoods, some nearly 300 feet tall, create a truly enchanting atmosphere. This easy 3.2-mile (5.2 km) hike winds through diverse terrain, from dense redwood groves to open grasslands, offering a peaceful immersion in nature. You'll encounter a mix of compacted gravel, soft trails, and even primitive rock staircases, with seasonal creeks and marshy areas adding to the varied scenery.
Planning your visit is straightforward, as Roy's Redwoods offers free admission and is generally less crowded than other redwood parks in Marin County. The trail is dog-friendly (on leash) and recent 2024 improvements, including boardwalks and steps, have enhanced accessibility. Be aware that some sections can get muddy in winter due to water erosion, so check conditions if hiking after rain.
This preserve stands out as one of only four locations in Marin County with old-growth redwoods, and it's the only one with free access for all abilities. It even served as a filming location for Lucasfilm's 1980s TV movie *The Ewok Adventure*. The trail's distinct ecosystem, including uncommon plants and Larsen Creek, contributes to its special character, making it a unique and accessible natural escape.

Along the trail you'll find redwoods, grasslands, and a nice viewpoint. This trail is pretty heavily trafficked and there is a lot of poison oak in the area.

From the high ridge sweeping views open up to both sides, most still densely forested and often covered in morning mist that helps this forest survive despite the long periods without rain.

The two Open Space Preserves meet in this valley of stately redwood trees that's refreshingly cool even in summer, which is welcome before or after the climbs that go both directions in and out of this valley.

On the site of the former golf course, the Trust for Public Land is developing an extension of protected land in the valley to protect it from development. The local community is active with many individual plots of veggie gardens.

293 forested acres overlooking the heart of San Geronimo Valley. Primeval groves of bay and redwood trees are the star attractions here, where scenes in George Lucas' The Ewok Adventure were filmed. For a peaceful getaway, meander down Roy’s Redwoods Loop Trail. It's a secluded ridge with sheltering fir, madrone, and oak trees. Look for "hippie trees." A 60's commune made their homes inside large hollowed-out trunks. https://www.marincountyparks.org/parkspreserves/preserves/roys-redwoods
