Mt Tamalpais State Park: Simmons - Mickey O'Brien - Cataract Loop Trail
San Francisco: Marin Headlands - Mt Tamalpais - Point Reyes
The Simmons, Mickey O’Brien, and Cataract trails join to form a short but varied loop through open meadows, deep woodlands and rocky outcrops from the Rock Spring Trailhead. This ecologically diverse route is ideal for families or a short trail run, and those with time can explore the picnic area, sunny slopes and natural spring at Barth’s Retreat.
