Marin County's Mountain Biking Renaissance: A Decades-Long Struggle for Trail Access

Sep 25, 2026, 11:47 AM

In a momentous development for the mountain biking community, particularly within Marin County, California—the historical cradle of the sport—a comprehensive proposal is now on the table to establish 27 miles of fresh singletrack trails. This initiative represents a considerable stride forward, especially given the region's enduring history of limited access for mountain bikers. The advocacy group, Marin Trail Stewards (MTS), previously known as Access4Bikes, has been at the forefront of this prolonged battle, aiming to overcome the numerous obstacles that have historically restricted cycling on singletrack paths in areas like Mount Tamalpais and the Marin Watershed. This ongoing effort has culminated in a proposed revision to the area's trails and roads management strategy, signaling a potential new dawn for enthusiasts.

The path to this potential expansion has been arduous, marked by strong resistance from various environmental organizations and the conservative stance of former governing bodies. Despite mountain biking's deep roots in the region, the community faced a consistent uphill struggle against a mindset that often viewed bicycles as incompatible with the sensitive ecological balance of the trails. However, a shift in leadership within the Marin Water Board, bringing in members more attuned to the needs of the mountain biking community, has catalyzed this change. This evolution in governance, coupled with persistent advocacy from groups like MTS, has paved the way for a more inclusive approach to trail management, promising to unlock new opportunities for mountain bikers while carefully considering environmental impacts.

Overcoming Historical Hurdles to Singletrack Access

For many years, despite Marin County being recognized as the origin point for mountain biking, the local cycling community faced stringent limitations on where they could ride. Access to singletrack trails, specifically within the Mount Tamalpais and Marin Watershed regions, was largely prohibited, a paradox that fueled a decades-long struggle. Groups like the Marin Trail Stewards (MTS), formerly Access4Bikes, tirelessly championed the cause for increased trail access, encountering significant resistance from various quarters. This persistent advocacy ultimately led to the strategic decision to overhaul the entire roads and trails management plan as the most effective route to secure singletrack access for mountain bikers.

The historical ban on mountain bikes from singletrack was rooted in concerns from the 1970s and 80s about the potential environmental impact of a then-new user group. Lacking sufficient data, authorities adopted a prohibitive stance, rather than actively seeking to understand and mitigate potential issues. Vernon Huffman, Executive Director of MTS, highlighted this rigid opposition, describing how previous leadership within the Marin Water Board adhered to an 'old guard' mentality, consistently rejecting proposals for increased bike access. This entrenched resistance meant that even expanding access to the existing 60 miles of fire roads was a significant challenge, showcasing the depth of the battle for recreational access in the region.

A New Era of Collaborative Trail Management

A pivotal moment in the fight for increased mountain bike access in Marin County arrived with a change in the leadership dynamic of the Marin Water Board. Huffman pointed to the election of new board members, including mountain bikers, as a critical turning point. This infusion of fresh perspectives replaced a long-standing conservative approach, which at one point even contemplated extreme measures like fencing off the entire watershed. The new board's understanding of the mountain biking community's needs fostered a more open and collaborative environment, paving the way for progressive changes in trail policy.

The initial breakthrough came with the successful opening of Liberty Gulch, a genuine singletrack trail, to mountain bikes. This victory, however, was swiftly followed by a setback when a proposed trial study for six additional miles of trails was halted by a lawsuit from environmental groups. Rather than dwelling on this defeat, MTS strategically opted to rewrite the entire 22-year-old Road and Trail Management Plan (RTMP), which lacked provisions for bike access on trails. After two years of meticulous work, involving environmental assessments, community engagement, and numerous public meetings, a draft RTMP has been presented. This ambitious plan proposes opening 27 miles of singletrack to mountain bikes through new construction, conversion of roads, adoption of social trails, and designating some existing paths as multi-use. While this progress is celebrated, it also presents new challenges, as some social trails will be decommissioned, and the majority of new access will be on multi-use trails, sparking ongoing discussions within the diverse user community.
