The Southwest Idaho Mountain Biking Association (SWIMBA) is a 100% non-profit, volunteer organization dedicated to building and preserving a world-class, multi-use trail network in Southwest Idaho. Since the early 1990s, SWIMBA has been enhancing SW Idaho’s trail recreation experience by:

  • Putting on fun events like the Tour de Fat! to raise funds for new trail projects
  • Educating riders about the responsible, shared-use of trails
  • Promoting and participating in the purchase of open space and trails
  • Working in partnership with the Ridge to Rivers Trail Partnership, the Bureau of Land Management, U.S. Forest Service and private landowners to build new trails and trailhead facilities
  • Leading trail rides and teaching kids and adults about mountain biking technique and bike maintenance
