What to expect on Pantoll Road loop from Mill Valley
Expect a diverse journey through varied terrain, from paved sections of Pantoll Road to fire roads like Old Railroad Grade and Old Stage Road, and even some technical singletrack. The route is a constant interplay of dense tree cover and open areas, but the real payoff comes with the panoramic vistas. You'll be treated to expansive views of the Pacific Ocean, the Marin Headlands, San Francisco Bay, and even the Farallon Islands on clear days, especially from scenic Ridgecrest Boulevard. Be prepared for some "relentless double-digit grade ascents" that will test your legs, but the historic West Point Inn offers a welcome break with its wrap-around porch and amenities.
Planning your visit
While Pantoll Road itself is largely paved, it is shared with vehicular traffic, so exercise caution. Good news for cyclists: the Easy Grade Trail is being developed as a safer, car-free alternative to connect Pantoll Station and the Mountain Theater. The Pantoll Ranger Station also provides a convenient rest stop with facilities. Given the challenging nature and potential for shared roads, planning your ride for off-peak times can enhance your experience.
