History of County Trails

On January 12, 2005, the San Diego County Board of Supervisors unanimously approved the adoption of the County Trails Program and the Community Trails Master Plan.  

The County Trails Program guides development of a system of interconnected regional and community trails and pathways. These trails and pathways are intended to address an established need for public recreation and transportation, but will also provide health and quality of life benefits associated with hiking, mountain biking, and horseback riding throughout the County's biologically diverse environments.

The County Trails Program involves both trail development and trail management on public, semi-public, and private lands. The Community Trails Master Plan is the implementing document for the trails program and contains local trails and plans for pathways that have been approved and adopted by the community.
