Across the Bridge and Into the Wind: Gravel Riding the Marin Headlands

Across the Bridge and Into the Wind: Gravel Riding the Marin Headlands

Ride where mountain biking began — gravel, cliffs, and skyline views in one unforgettable loop.

Continue Reading

The morning light deepens as you cross the Golden Gate Bridge, the city shrinking behind you into a low-slung silhouette and a cool Pacific wind already nudging your jacket. By the time you roll into the Marin Headlands your lungs taste like salt and eucalyptus; the road pitches up and the city falls away, replaced by scrubby bluffs, wartime concrete batteries, and views that stretch from the Farallon Islands to the shadow of Twin Peaks. The Headlands are not just dramatic scenery. They are where modern mountain biking was born and where gravel riding becomes a conversation between rider and coast — a place that dares you to climb, rewards you with ocean panoramas, and tests bike handling on raw, variable terrain.

Expect Wind

Bring a windproof layer and time your climbs to minimize sustained crosswinds on exposed ridgelines.

Tubeless or Tough Tires

Choose tires 36–40mm with puncture protection or run tubeless to reduce flats on mixed gravel.

Start Early

Begin before 8am to beat fog and parking crowds and to catch the most stable wind window.

Respect Wildlife Zones

Give seals and shorebirds wide berth and avoid stopping in marked nesting or haul-out areas.
