Access4Bikes (A4B)


A4B is all about getting fair and reasonable access for mountain bikers to the trails on our public lands in Marin. The reasons that access is currently so restricted are political in nature. A4B exists in order to address these political reasons with political solutions, which include taking a direct role in trail access decisions by public land managers, electing officials who are willing to be fair about bike access, mobilizing mountain bikers to become a political force on their own behalf, and building an informed community of advocates for fair access.
