Loop Trail in Roy's Redwoods Preserve is closed for public safety, due to fallen trees and storm damage.
Overlooking the heart of the beautiful San Geronimo Valley, Roy’s Redwoods Preserve is a perfect place for a quick escape. From the main entrance along Nicasio Valley Road, you enter a picturesque meadow surrounded by sheltering bay trees interspersed with clusters of towering redwoods. These redwoods are among the largest in the county. Remember that these specimens are just the offspring of even more massive “mother trees” that once stood in the center of these rings of 200 foot tall sprouts. From the meadow you can choose from a few shaded trails that loop through this 293 acre preserve. You may also choose to climb the Dickson Ridge Fire Road to enjoy sweeping views that stretch from Mt. Tamalpais in the east to Mt Wittenberg in the west.
The primeval groves of bay and redwood were once the setting for a George Lucas movie, The Ewok Adventure. Prior to becoming an MCOSD preserve, several of the great rings of redwoods were inhabited by members of a loosely organized commune. For a perfect quiet getaway, try the Roy’s Redwoods nature trail. This short loop walk meanders along a secluded ridge among sheltering fir, madrone, and oak trees.
From Hwy 101 in Larkspur, take the exit for Sir Francis Drake Blvd west 8.6 miles, turn right onto Nicasio Valley Rd. Gate is approximately 0.5 miles up on the right.

Look for Pileated Woodpeckers and Black-throated Gray Warblers during the day, and look (and listen) for Barn and Great–horned Owls in the evening and early morning. Kingsnakes, racers, ringneck snakes, and rattlesnakes are all here too, in fact so is every species of lizard found in the county!
