Great viewpoint along Stagecoach Fire Road. There are picnic tables, so this is a great place for a break to enjoy the wonderful views of Mount Tamalpais.

Pantoll Road is a beautiful, mostly paved route through Mount Tamalpais State Park, connecting the Panoramic Highway to Ridgecrest Boulevard. It winds closely along the curves of the hillside, with some shade from the trees in some spots. There are fantastic views along the way of San Francisco and the Marin Headlands, with incredible viewpoints over the Pacific coastline.
