The East Bay Regional Park District began acquiring land for Black Diamond Mines Regional Preserve in the early 1970s. Today, most of the mining district is within the Preserve's nearly 6,096 acres. The area is an ideal location for hiking, picnicking and nature study. Naturalists conduct a variety of programs relating the Preserve's natural and historic resources.

Did see a coyote on this trail. Not as well marked as other trails, but still a nice hike!

It was really fun and historical! There's so much to do! It was a really clean park. There are numerous slopes but nothing to hard.

overall good but long day if you bring the kiddos. our little one, 8yrs had a couple break downs due to the heat but we ended up back at the car finishing 6.75 miles. Got a tad lost in the beginning, the trail wasn't clearly marked at the start. Nice views, would do again.
