Give Back To The Trails You Love to Ride! 

The San Diego Mountain Biking Association needs your partnership as we CLIMB together to new heights! SDMBA is experiencing amazing growth, increased political influence and strong visibility within our community. But without your help, trails will continue to be closed and access to open space for cyclists will be limited.

SDMBA invites you to join in our efforts with a donation - 100% stays in San Diego. Your generous donation will support cycling programs, community events, and will allow us to acquire tools, equipment, and materials to build and maintain trails. In addition, your support provides resources for our staff and our volunteer trail experts to partner with user groups, land managers, and policymakers to improve access and your trail experience.

Goals for 2020 and beyond:
  • Building more new trail at Black Mountain (including Black Widow!) and developing work plans for other projects and maintenance.
  • Working closely with the Cleveland National Forest on a formal Memorandum of Understanding for future work the Mount Laguna Trails Restoration Project.  We have entered into formal Collection Agreements with the Cleveland National Forest as a partner providing funding to drive projects like this forward.
  • Trail rehabilitation at Mother Miguel (Rock House) in Chula Vista starting in the winter of 2018 and continuing into 2020.
  • Continue to work with the County of San Diego on trail improvement and plans as well as the opening of the Sweetwater Bike Park in early January 2020.   We are also working on additional bike park/pump track plans in the Otay River Valley (County of SD), the City of San Marcos and others.  
  • Our top priority always is advocating for more legal trails in San Diego County!
