Horse Hill Bike Path

Highlight (Segment) • Cycleway

Paved bike trail along the Highway 101 corridor, lowest crossing of Horse Hill between Mill Valley and Corte Madera

Tip by

11.0 km

The Sausalito houseboat community is full of architectural gems and repurposed old working boats, and each is wonderfully unique. Bikes are not allowed on the dock, so you must park your bike to get a closer look; however, remember to be respectful when visiting, as these are residential homes, and you are close to someone's living space.

Highlight (Segment) • Settlement

If you're riding into Sausalito from San Francisco then you'll be coming in via Alexander Avenue. You'll be treated to great views across the water, and the classic Bay Area homes built along the cliffside.

Fort Baker

Highlight • Historical Site

Fort Baker is a historic army post located in the Marin Headlands. The post, built between 1902 and 1910, is one of the park’s best examples of the army’s “Endicott Period” military construction, named after the late 19th century Secretary of War, William C. Endicott. Mostly transferred to civil purposes since 2000 including hotels, the Children's Discovery Museum, etc., the U.S. Coast Guard Station Golden Gate, located at Horseshoe Cove, is responsible for search and rescue missions, homeland security, maritime law enforcement, maritime environmental protection and boating safety. The Travis Air Force Base continues to operate the Sailing Marina Center at the Presidio Yacht Club. nps.gov/goga/learn/historyculture/fort-baker.htm

Bobcat Trail

Highlight (Segment) • Trail

Bobcat Trail drops into Gerbode Valley from the height of the ridge separating Tennessee Valley from Rodeo Valley, offering expansive views West across the Marin Headlands to the Pacific Ocean, and South toward the ridge along the Golden Gate, with San Francisco and the top of the Golden Gate Bridge tower peaking through.

Marincello Trail

Highlight (Segment) • Trail

Marincello Trail climbs from the Tennessee Valley parking/trailhead to the top of the ridge separating it from Rodeo Valley. While climbing out of Tennessee Valley it offers spectacular views of the North Bay to San Rafael, to the West all the way down to the pacific, and to San Francisco and Golden Gate Bridge peeking through the ridgeline to the South. It is named for the road that was constructed in the 1960s by developers hoping to build a massive residential community into the headlands, which was finally defeated in the 1970s when local residents managed to put the entire area under protection.

Description

If you're looking for a mountain biking route that packs a punch with diverse terrain and panoramic views, the Bobcat Trail – Marincello Trail loop from Larkspur is a rewarding ride. This moderate 28.0-mile (45.0 km) loop involves a solid 2006 feet (612 metres) of climbing, but you'll be back in just over 3 hours, making it an excellent choice for intermediate riders seeking a substantial outing without committing to an all-day epic.

What to expect on Bobcat Trail – Marincello Trail loop from Larkspur

The journey kicks off with the Marincello Trail, a steady, gradual climb on a well-maintained dirt and gravel road. As you ascend, prepare for spectacular views opening up across the North Bay towards San Rafael, with the Pacific Ocean to your west and glimpses of San Francisco and the Golden Gate Bridge. The Bobcat Trail then offers a fast, smooth fire road descent into Gerbode Valley, but keep an eye on the 15 mph speed limit. The route continues to challenge with sections like the Miwok Trail's strenuous fire-road climb and the Old Springs Trail's enjoyable singletrack, featuring unique low wooden steps and stone-paved dips. This loop demands good fitness and confident bike handling, especially on the varied surfaces.

Planning your visit

The common starting point is the Tennessee Valley parking lot, which offers restrooms, but be aware it can fill up quickly on weekends, so an early start is advisable. E-bikes are permitted on this route, offering an option for those who want a little assistance on the climbs. Remember to respect the enforced 15 mph speed limits on sections like the Bobcat Trail, as radar speed traps are occasionally present. This loop is best enjoyed on a clear day to fully appreciate the panoramic views across the Marin Headlands.
