August 23, 2023, David Hansen Trail

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.

Eastern start of a gravel trail along Sir Francis Drake Blvd, from Lagunitas School Road to the Trailer Court to give kids safe walking access to school, and provides access to two parallel trails climbing north up to French Ranch OSP.

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.

The trail begins at the locked gate here, follows the fire road through French Ranch Open Space Preserve, and continues onward to Barnabe Mountain in Samuel P Taylor State Park. Excellent views all along the ridge.

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
