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
