As we enter the spring of 2021, we continue to meet these challenging times! Things are beginning to look up, but we still have large group events are on hold while we monitor how things progress. Our quarterly advocacy and board meetings will continue virtually. We look forward to a more normal fall and can't wait to see you all more often!  Our staff continues to do work safely in the field and on trail advocacy efforts around the county. We have protocols in place with some land managers for small volunteer events so stay tuned for upcoming opportunties to help. 

We thank everyone for their ongoing support!  It means so much to the trails we all love.  

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

Over 1500 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.
