This slow-paced walk will take us from the San Andreas trailhead up to the nearby volcanic-rock hill and the woodlands by the water tank. From there we’ll cross a marshy field which is usually rich with annual wildflowers. Then we’ll go uphill to the largest vernal pool in Marin County.

Plants usually seen on this hike include striped coral-root orchids in the woods and a rare white water buttercup floating in the pool.

Bring a sack lunch, water, and a good hat.

Meet at the San Andreas Dr. Open Space entrance, where you’ll find streetside parking.
