Marin Municipal Water District has approved an 11-mile Ridge Trail route from Mountain Theater to San Geronimo Ridge to improve connectivity for mountain bikers, equestrians & hikers alike.
The Mount Tamalpais Watershed Parallel Ridge Trail uses a new route connection along existing trails to address the bike and equestrian Ridge Trail gap north of Mountain Theater. These trails, managed by Marin Municipal Watershed District, connect Ridge Trail users in a unique way to the Mt Tamalpais Watershed Area by offering recreational activities balanced with proper reservoir and ecosystem management.
This new parallel now allows all user types to navigate this part of Marin County without having to travel alongside cars on Ridgecrest Blvd.

This Ridge Trail connection became possible after a restoration project at Azalea Hill was completed, which included a change-in-use project on the Liberty Gulch Trail that now accommodates hikers, bikers, and equestrians.
The segments that make up this new Ridge Trail section include
- 3 miles on the Pine Mountain/San Geronimo Ridge
- 2 miles of Liberty Gulch Road
- 0.39 miles of Bullfrog Road
- 5 miles on Lagunitas-Rock Springs Road to Alpine Lake, and
- 0.25 miles of East Ridgecrest Boulevard
Explore the New Route:
Hikers, mountain bikers, and equestrians can all travel the new route between Rock Springs Trailhead and White Hill Trailhead (~13 miles).
Use this AllTrails Route Map in combination with Ridge Trail Map: Bolinas Ridge to Samuel P. Taylor State Park to navigate.
More maps and information coming soon.
