Explore the most popular horseback riding trails in Black Diamond Mines Regional Park with hand-curated trail maps and driving directions as well as detailed reviews and photos from hikers, campers and nature lovers like you.

Beautiful view especially at the beginning couple of miles. Going up the rose hill for a panoramic view of the rolling hills.

Great trail to do especially in spring or winter... Too hot and dry in summer.

Day one backpacking. Great place!

This was a nice hike and if I lived in the area I'd do it often, but it wasn't worth the 45-minute drive. There were tons of very cute cows blocking our trail and the recent rains combined with the cow hoofprints made it a muddy and uneven (but fun) experience. This is definitely a hike to do in winter and early spring as there is no shade and Antioch gets pretty hot in the summer/fall.

Great views!

Very scenic, you will not be disappointed! I love that I can bring my dog with me up there. I would bring a lunch and sit by the edge to enjoy the view for a few minutes before my trek back down. Bring good hiking shoes for grips....the path vary from smooth to rocky and uneven.

There is a kiosk at the entrance to the park which will collect $5/car to enter the park if the kiosk is staffed. When I went on a Saturday in January at 10:30 a.m. though, there was no one at the kiosk so we did not have to pay the entrance free. I would recommend that you expect to pay $5/car in case the kiosk is open when you come though.

Note: The trailhead is not the first parking lot that you see after the kiosk. Drive father down the road into the park to find the trailhead parking lot.

This trail will feel moderate for moderately experienced hikers and will feel difficult for inexperienced hikers or folks who are out of shape. This park reminds me of Briones Regional Park with rolling hills, city views, and lots of cows grazing in the park. Except I saw about twice as many cows here as I did in Briones Regional Park.

Definitely watch your feet for cow feces because it’s pretty much everywhere. I also couldn’t really find a good place to break for lunch midway through the hike, so settled for a scratchy patch of grass in semi-shade in between piles of cow feces.

There is a steep ascent on part of this trail that will freak out inexperienced hikers and make them rethink coming. If you bring a group of people with a mix of hiking experience, this is where you will see the most difference in people’s fitness levels and most likely people will not be able to hike at the same pace as at flatter parts of the trail.

This hike is ideal to do during cold and cloudy weather since there is full sun exposure pretty much the entire trail. Make sure you bring sunscreen, a hat and sunglasses even when going during winter. Also bring plenty of water since the sun will wear you out.

I’m glad I experienced this park, but don’t see myself coming back soon.

beautiful trails out there, kids liked all the different mines and sights. lower trails are fairly muddy after the rain, but once you get up the hill a bit it is rockier and less muddy.

This is one of my favorite trails in Black Diamond Mines. I like to hit it with my 2 year old son in a hiking carrier near the end of the day. I’m tall and there’s no brush for me to dodge!

The trail is what you make of it. If you take your time, it’s pretty easy after the first mile. I am always up against the park closing, especially in the winter, so I do this as fast as I can. It’s a great workout, if you keep the pace up.

Also the views from the top are amazing. In the early morning you can see the sun reflecting off the delta, in the evening you can see the sun setting with Mt Diablo in the background.

Great Hike. I did this loop Counter Clockwise. Pretty flat at the start after .7 miles at the switchback too river view trail it starts too climb. Not super steep. Lots of cows. End of the loop is really steep going down.

Some steep parts but nothing to bad. Good trail for the pups and the cemetery is neat!

Great trail, very scenic, definitely challenging. There is very little sun cover, so bring plenty of water and sun protection. When you get to the first fork, go straight instead of up the giant hill on the left, you have enough of a challenge later. Enjoy the views and the natural beauty because it is quite something out there. Be sure to keep an eye out for the ridge trail to loop you back to the cars (if you strictly follow the Stewartville trail signs, you will find yourself on a not so scenic 1.6 mile detour that is not worth it). Please note, that the ridge trail is definitely the challenging part of the "loop", so save some energy and water for it. Also be warned, if you're planning on bringing your dog, keep him/her on leash as we did encounter a rattlesnake today (this also being the reason for docking one star). Overall, we had a great adventure but were slightly unprepared. Enjoy!

Enjoyed this hike! Definitely has a few areas where you can go where it can be more challenging or easier depending on what you are looking for. Awesome place for pups! Only negatory would be the very few shade spots.

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.

this was an ok hike..no scenery until you get to the other side of the mountain. over all good.

Trail was in bad condition due to the past rain and the livestock stepping all over the place. Nice for wildflowers, but nothing spectacular.
