Tips from the Community
The eponymous name of this hill mostly refers to the climb to this point from the beach about 1300 feet (400 meters) up. Deer Park Fire Road is actually reasonably gradual, following the ridgeline. Still, it is a good place for a rest, take in the views to the Pacific, and refill the water bottles at the water fountain, and read info panels about the recent history.

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.

There are still remnants of old train platforms visible where the Gravity cars used to intersect with the Mt Tam Railroad.

Uphill from this intersection a portion of the Railroad Grade has been taken over by Fern Canyon Rd after the Mt Tam railroad closed. A short distance uphill on pavement brings you to the end of Fern Cyn. A bit before the end the Railroad Grade gravel forest road splits off again to the right. The Temalpa Trail that joins here is steep with stairs, not open to biking.

Sweeping views south and east, all the way to SF, and Mt Tam right above behind you to the north. The bench is dedicated to the family who built their house in front of you 60 years ago.

Great singletrack that is also perfectly rideable on a gravel bike. The trail is most fun riding in the northern direction into Tennessee Valley.
