Improving trail access for mountain biking in

San Diego County since 1994

Over 1900 members have joined the San Diego Mountain Biking Association to provide a unified voice to make mountain biking better in San Diego County.   Our trail advocacy efforts focus on developing positive working relationships with land managers and other decision-makers regarding public land-use policies and open space management. We support sustainable recreational trail opportunities balanced with conservation.  The San Diego Mountain Biking Association works to educate all trail users to respect the environment and recreate responsibly.  

Join the SDMBA in trail advocacy and supporting mountain biking in San Diego!
