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.

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
