The Black Diamond Mines Regional Preserve is a lesser-known gem in the Bay Area. It has over fifteen miles of trails that are open to hikers, mountain bikers, and equestrians, making it one of the largest parks in Contra Costa County. The park has three primary trailheads with parking for visitors: Potrero Hills, Valle Vista, and Canyon Trails. All offer their own unique scenery; from scenic views at Potrero Hill to panoramic vistas at Valle Vista Trailhead. Visitors can enjoy hiking up Mount Diablo on any number of shorter trails or explore its summit via the longer routes to make this a half-day or full-day adventure! 

The Black Diamond Mines Regional Preserve is an excellent place for locals and travelers.  The black diamond mines of the 1800s have been transformed into a beautiful and natural wonderland for hikers and nature lovers. There are over 15 miles worth of trails to explore, some that lead up Mount Diablo or through picturesque canyons. The park is open year-round from sunrise until sunset with seasonal closures but offers various day-use activities including picnicking, hiking, biking, horseback riding, birding (May through October), dog walking (after obtaining an off-leash permit)
