About The Trail

Spanning the distance between Briones Regional park and Mt. Diablo State Park, this trail serves the communities of Lafayette and Walnut Creek and makes important connections to major regional trails, including the Contra Costa Canal Trail, California State Riding and Hiking Trail, and the Iron Horse Regional Trail. The Briones-to-Mt. Diablo Trail also connects schools, community facilities, and city parks and open space areas, including Briones Regional Park, Larkey Park, Heather Farm Park, Shell Ridge Open Space, Diablo Foothills Regional Park, and Mt. Diablo State Park. This trail is multi-use with paved and unpaved portions, and offers opportunities for trail users of all abilities. The paved portions (including the segment shared with the Contra Costa Canal Trail) are accessible to trail users in wheelchairs. Sweeping views of Pleasant Hill and Walnut Creek may be seen from portions of the trail.

Leaving Briones, the trail passes over Acalanes Ridge (Walnut Creek Open Space) into Larkey Park and past the Alexander Lindsey Museum. It shares a right-of-way with the Contra Costa Canal Trail for a short distance, passes by Heather Farm Park, goes into Shell Ridge Open Space, enters the Park District's Diablo Foothills Regional Park, and finally enters Mt. Diablo State Park. The trail provides access to community facilities and natural areas. Scenic vistas, wildlife viewing, and beautiful natural settings reward users of this regional trail corridor.
