Black Diamond Info



Previously home to Native American tribes, then a cattle ranch, then a coal mine, it is now a preserve that features a number of mine tours in addition to over 65 miles of trails, which traverse grasslands, foothill woodlands, mixed evergreen forests, chapparal, stream vegetation and exotic plantings.

What Makes It Great

The park also supports a healthy wildlife population that includes coyotes, snakes, foxes and even mountain lions. At Black Diamond Mine, there are two main campgrounds, but one is primarily for educational groups. The public site, Stewartville Backpack Camp, is $5 per camper per night and campers are limited to two nights during peak seasons. After pitching camp, catch one of the tours or hike the trails. Look for mining features like the Eureka Slope, Prospect Tunnel and the Powder Magazine. 

Who is Going to Love It

The camping and backpacking here is low-key and good for families, casual adventurers, and those intrigued by the history and wildlife in the area.
