The hills of Black Diamond Mines Regional Preserve east of Concord, California, have been returned to their natural state, making them ideal for hiking, birdwatching and other outdoor adventures. It wasn't always like this: In the 1800s, a coal economy ruled the region. When the coal ran out, the miners moved on, leaving tombstones where towns once stood. Mining resumed years later: this time they dug sand for a local glassmaker. Tours of the old silica sand mines are a popular fixture of Black Diamond Mines. This route starts out in the parking lot on the old Somersville town site, passing the Rose Hill Cemetery and moving on to Nortonville, another town site lost to time.

Good trail, did it with 10lb packs to give a couple people a "backpacking simulation". Good day!

The trail goes through 3 different old mining sites and the Rose Hill Cemetery. It as some pretty good hills and is on the upper side of moderate. I did it in late march so there were some wildflowers starting to bloom. Very good winter and spring hike and probably a 3 1/2 stars for me.

I started at the Nortonville Trail, continued onto the Black Diamond Trail, I followed the Black Diamond Trail and completed the loop. Total distance was 5.4 miles, 1,227 feet elevation. Most trails were wide and easy graded except the last couple miles were single track. I enjoyed reading all of signs that showing the historical local coal mining. I also enjoyed views of the surrounding area.

Loved the history of the mines, their cool temperature was a welcome relief from hot weather. Walking on sand trails was unique for a non-beach setting. Needed more trail markers and remember to have cash for parking.

Nice hike with beautiful views once you reach the top. The first half of the hike, to about the 2.5 mile mark, is steep but once halfway it's mostly downhill from there. Go early in the morning, especially in the summer months, to avoid the heat and bring plenty of water.

Not much shade in some spots. There are some really tough increments to start and finish.

Overall... Fantastic views. Clean. Clear. Can't wait to go again.
