Black Diamond Mines Loop Trail is a 5.4 mile heavily trafficked loop trail located near Antioch, CA that features beautiful wild flowers and is rated as moderate. The trail offers a number of activity options and is accessible year-round. Dogs and horses are also able to use this trail.
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.
Beautiful golden grassy area, loves the scenery. Far away from everything!
Good trail that isn't that steep but hot. Best done any time but in the summer heat.
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.
i loved this trail, quite steep for a bit but worth it for the views.
It is a very well kept and has vast open space. It ranges from easy to moderate but has great views no matter which direction you are traveling. We spotted some wild turkeys and near the beginning of the loop there are cows grazing. It's great place to get out doors and get some exercise and bring the family too! As well bring a picnic if you prefer, they have a picnic area too!
Excellent, for an early morning hike. Lots for nice vistas and open space.
Nice day and beautiful place.
Great place to go for a hike with many options for length of trails. Dog friendly! Which is a huge plus for me. I took my kids and dogs on a 6 mile hike. It was beautiful!
Beautiful views of the rolling hills and valleys.
I grew up in Antioch, and have rode and hiked Black Diamond many, many times. Springtime is best, with all of the wildflowers in bloom. The scenery coupled with all of the history is absolutely fantastic.
