Marin County Unveils Expensive New Bike Trail After Decade-Long Wait

Jan 26, 2026, 2:29 PM

Marin County, despite its legacy as the genesis of mountain biking, faces significant challenges in developing new trails. However, the Marin Trail Stewards (MTS), previously known as Access4Bikes, are actively addressing this by leading trail construction initiatives. Their recent accomplishment, the Caballo Rojo trail, exemplifies their commitment to expanding riding opportunities, even when faced with substantial costs and efforts.

The Caballo Rojo trail, a one-mile, downhill-only route designed for mountain bikes, took ten years and $650,000 to finalize. This extensive project, located within Camp Tamarancho, offers typical flow trail features such as berms, grade reversals, and rollers. Beyond providing an exhilarating ride, Caballo Rojo serves a practical purpose: it diverts riders from a busy access road and alleviates congestion on the Alchemist Trail, offering a new entry and exit point for the Tamarancho Loop.

MTS employs a multi-faceted strategy to facilitate the approval of mountain bike trails in Marin County, including seeking opportunities on private land to bypass bureaucratic complexities and advocating for changes in trail use on public lands. The organization also champions the formal adoption of existing social trails and focuses on converting roads into trails. This community-driven approach, evident in the dedication of numerous volunteers, is crucial for overcoming obstacles and expanding the region's network of mountain biking trails, ensuring the sport's continued growth and accessibility.

The successful development of trails like Caballo Rojo demonstrates the power of perseverance and community involvement in transforming ambitious visions into reality. It underscores the importance of dedicated organizations and enthusiastic volunteers who overcome significant hurdles to create valuable recreational spaces. This spirit of collaborative effort not only enriches local communities but also ensures that the joy of mountain biking remains accessible, fostering a healthier, more active lifestyle for all.
