Opening this bike tunnel through the renovated trail tunnel as part of the 2010 redeveloped rail connection from Larkspur Ferry to Santa Rosa closed a crucial gap in the bike commute to San Francisco.

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.

This large group picnic area is a lovely spot under a shady grove of towering redwoods that sits along Lagunitas Creek. There is piped drinking water and restrooms nearby, and if it is not in use, it is an excellent place to stop for lunch. If you are bike touring with friends and wish to spend time here, you can reserve this spot through the Samuel Taylor State Parks' department website.

This tidal sanctuary runs along the Mill Valley-Sausalito Pathway and the Charles F. McGlashan Pathway. More than 400 species of migratory birds rest here after their long flights, and if you pass through in the early morning or late evening, the sunrises and sunsets reflect beautifully on the surface of this 106-acre marsh.
