Pine Mountain Loop

25.2km

The Pine Mountain Loop offers a challenging mountain biking experience through Marin County's scenic landscapes. You'll navigate primarily fire roads, but expect very rocky and steep sections, some with grades over 20%, that demand technical skill. The route rewards your effort with expansive views of the San Francisco Bay and Tomales Bay, and a unique passage through a dwarf Sargent cypress forest.

This moderate 15.6-mile (25.2 km) loop involves a significant 2349 feet (716 metres) of elevation gain, typically taking around 2 hours and 36 minutes. Winter flooding can create ruts, so be prepared for potentially rougher conditions. The trail can feel remote in parts, so carry enough water and supplies for the duration of your ride.

Beyond the physical challenge, this trail is steeped in mountain biking history, overlapping with Repack Road, considered a birthplace of the sport. It also forms part of the long-standing Thanksgiving Day 'Appetite Seminar' ride. The route offers a substantial, winding descent if ridden clockwise, but watch out for the notorious 'ET curve' known for spills.

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.

The view from the start of this trail is amazing with the rolling hills leading into the mountains. There is lush greenery as far as the eye can see as Mount Tamalpais Watershed meets the Cascade Canyon Preserve.
