Experience San Diego County trails, one of the most diverse trail systems in the nation! Some trails offer simple strolls along placid streams while others take you over rugged mountains and isolated valleys. Some are easy, flat paths and others take you up and down a mountain - you pick the path. Discover 360 miles of hiking, biking and equestrian trails in more than 100 parks and open space preserves. 

View our Park Finder map to find a location that suits your individual needs and preferences, or pick trails based on destination and park type through our partner site,  GetOutsideSanDiego.org.

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.
