Complete Rules

The San Diego Mountain Biking Association is a 501(c)3 nonprofit and our work is supported by generous donors like YOU!  

We are gearing up for a very busy 2021-22 Trail Work season on projects throughout the county from Mount Laguna to Daley Ranch to Chula Vista and more!  When you donate to this general fund, we promise to use your gift where it's needed most.  Whether that's covering operating costs, clearing a fallen tree, or buying a shovel for a volunteer to use, we'll make sure your money has the most impact on our trails and our community.  

Past contributions and grants have allowed us to purchase and maintain a mini-excavator, a motorized wheelbarrow, a plate compactor, a water buffalo and water distribution equipment,  and loads of hand tools and materials to help us maintain and build trails.  In addition, your support provides resources for our staff and our volunteer trail experts to partner with user groups, land managers, and policy makers to improve access and your trail experience.  Learn more about current projects here past projects here.  

Goals for 2021 and beyond: 

  • New trail connectors and trail maintenance at Black Mountain Open Space Park
  • Partnering with the City of Escondido and other community partners on improvements at Daley Ranch including a Master Trails Plan 
  • Working closely with the Cleveland National Forest the Mount Laguna Trails Restoration Project 
  • Trail improvements at La Costa Preserve in Partnership with the Center for Natural Lands Management
  • Trail improvements in Chula Vista as part of the Rice and Snake Canyon Loop Trail Pilot Program
