As we all continue to work through the challenges that 2020 has delivered to us, we have had to cancel all events including large volunteer trail work days and in person meetings.   We have taken our board and committee meetings and our quartlerly advocacy meetings online.  Our staff has continues to do work safely in the field and on trail advocacy efforts around the county.  We are working with our partners on protocols to get small volunteers back out safely to trail work events.  Stay tuned for opportunities.

Improving trail access for mountain biking in San Diego County since 1994

Over 1400 members have stepped up to help SDMBA make mountain biking better for everyone in San Diego County. SDMBA advocacy volunteers provide a unified voice for trail users in public land use policies favoring sustainable outdoor recreational opportunities. Liaisons, trail builders, and other advocates seek out and build harmonious unified alliances and partnerships with businesses, land managers, and communities. Specialized volunteer-run programs support this mission and further inspire youth to explore and learn about nature and become its future stewards.
