Blackridge trails
The Blackridge trails start at Blackridge Pond in Herriman. There are three major trails reached via the Blackridge trail: Diamondback, Sidewinder, and Eric's trail. The loop at the top of Eric's is called the Mustang Loop.
A ride here can be easy, such as the "snake loop" of 3.1 miles and 400 feet of fairly gentle climbing, or tough like Eric's trail with over 1000 vertical and some rocks to dodge.
The Herriman singletrack trail system was started in 2013, and is still under construction. The system is planned to expand to around 20 miles, with connections to the Rose Canyon Trails and Butterfield Canyon on the north and a future southbound Bonneville Shoreline Trail. For now, it provides another "off-season" low-altitude riding opportunity. See the Juniper Crest page and the Herriman Bonneville Shoreline Trail page for additional riding that you can link to from Blackridge.

Bikes on the rack tell me that this family is cooling off in the water of Blackridge Pond after their bike ride.
All trails are reached via the Blackridge trail, which starts at the northwestern end of the parking strip for Blackridge Pond in Herriman. The Pond parking can be hard to find if you're not a local, so I recommend a mobile for navigation or a printout of the ride guide from this website.

There are two additional web pages that provide extra details on some trails in this system. These are the Rodeo DH beginner downhill trails, and the upper-mountain expert trails Mojo, Rawhide, and Hardlick .

The most popular ride (2018) seems to be a 3.1-mile lariat loop. This quick ride climbs Blackridge to Sidewinder, climbs over the hill on Diamondback then rejoins Blackridge to head downhill. We'll call it "the snake loop." See the ride guide below.
Second most popular is a lariat ride up Eric's trail and around the Mustang loop clockwise. I recommend this ride highly (see video below).

Approaching the fork with the Sidewinder trail (the sign on the far left). A left turn continues uphill on Blackridge.
The Blackridge trail starts at Blackridge Pond and climbs 0.9 miles up the mountain.. At the top of Blackridge, it continues as either Eric's Trail or the Diamondback trail. Elevation gain is 250 feet.
Sidewinder forks away from Blackridge on the lower mountain, just 0.3 miles from Blackridge Pond parking. Keep left to stay on Blackridge, and stay left as you pass the exit from the Rodeo DH trails.

At mile 0.7, the Rodeo DH trails fork away on your right. These are two beginner and child-level one-way downhill trails. See the Rodeo DH page for details .

Trail fork at mile 0.9. Right and a 180 turn sends you on Diamondback, up and over the little hill. Straight ahead is the big climb up Blackridge.
Blackridge continues uphill to Eric's trail, which climbs to a high ridgeline on the east slope of South Mountain. A hard left at this trail fork will put you on Diamondback. Stay left and straight to make the Eric's trail climb.
Eric's Trail
Eric's Trail connects the top of the Blackridge trail to the Juniper Crest Loop on the other side of the hill. It's 4.7 miles long. Eric's climbs 800 vertical feet (1050 from the Blackridge Pond trailhead) to a high ridgeline at 6150 feet before descending. As you approach the top of Eric's, the Mustang Loop offers a lariat-loop ride option.

Eastbound toward the first ridge viewpoint on the lower ridge. The terrain has changed from grass to sage.
Shortly after you make the turn in Secret Canyon at mile 1.6, a trail forks away to your left. This connects to the utility road. No reason you'd want to go there unless you're making an emergency bailout down to the homes of Herriman.

You'll pass the exit from Hardlick , coming from uphill on your right, at mile 2. 

At mile 2.2, there's a trail fork for the Mustang Loop. Go either direction if you're doing the lariat out-and-back. Eric's trail is the one to your right. The trail straight ahead on the left used to be called Eric's, but it's now designated as the Mustang Trail.

From the fork with the Mustang trail on the ridgeline, Eric's trail continues down on the eastern side of the hill. Pass the Mosey trail (keep left here) as you descend. After a couple of switchbacks, Eric's heads north. It descends 900 vertical feet over two miles down to the Juniper Crest trail. It's intermediate in tech requirement. Note that in 2023, the older path for Eric's (to the left as you approach the city) has been closed. Keep left here and descend.

We're looking east across southern Salt Lake Valley, but you can see the mountains of Utah County above Traverse Ridge on the right.

Eric's trail is also a reasonable climbing option from Juniper Crest. There's less parking at the bottom of Juniper Crest (at this time) compared to Blackridge. The upside is, fewer people to contend with. For veteran riders, the bottom of Eric's Trail is the old -- formerly closed -- Firebreak trail.
Mustang Trail and Mustang Loop
The Mustang trail is 1.1 miles long, with 200 feet of elevation change. The top is on Eric's trail at mile 2.4 (3.3 from Blackridge Pond trailhead). The bottom of Mustang is on Eric's 1.1 miles downhill on the western side of the ridge. You can use it as an alternate for the Eric's Trail ride.

The Mustang trail climbs steadily up to the eastern ridgeline. There's a small technical loop here with some nice views. Then it turns south to rejoin Eric's Trail. The trip around the loop of Eric's and Mustang is 2.3 miles. The downhill is a lot of fun -- swoopy and twisty.
The top of the Mustang trail climbs to a viewpoint on a ridge at mile 2.5 from the trailhead, but hang on, it gets better. At mile 3.0, elevation 6000 feet, you'll hit a trail fork. Left takes you on a loop to the top of the little knoll.
From this viewpoint among the rough granite rock, you can see both Utah and Salt Lake counties. You'll rejoin the main trail 30 feet away from the trail fork that took you into the viewpoint loop.

Not too bad. You just need to slow down a bit to steer the bike between the boulders.
After climbing to 6150 feet elevation southbound, the trail hits a fork on the ridge. At the trail fork, both options are Eric's Trail. Left takes you down to the Juniper Crest trail, while keeping to the right completes a loop for the lariat ride. The right fork is also your route to Mojo, Rawhide and Hardlick.
If you descend the western side of Eric's back to Blackridge, there are a couple of rock challenges. Some you simply have to finesse your way through, others are optional rollovers or drops on the side of the trail.

Sidewinder

Just getting started on Sidewinder, looking back at Blackridge Pond. As you can tell, we didn't have to climb very much.
Sidewinder begins at mile 0.3 from Blackridge Pond. Turn right off Blackridge and make a 180. The trail will climb gently as it contours around the hill. Technically, it's very easy, and quite suitable for beginners.
There are constant views from Sidewinder. Granted, you're not very high up. But to your right, the view will change from the south valley with the Jordan Narrows and Traverse Ridge to the northwest where the massive Kennecott tailings cover the slopes of the Oquirrh Mountains.

Sidewinder is only 0.6 miles long. It will climb less than 100 vertical feet, then descend a bit before ending on the northern side of Diamondback. From here, you can keep to the left to climb uphill. The Bonneville Shoreline Trail is 0.2 miles away, or you can stay on Diamondback to ride over the hill for a loop ride.

The trail climbs through a burn scar from the big fire a couple of years ago. This photo is from 2014. In 2018, I didn't even notice the signs of the fire.
The Diamondback trail extends north from mile 0.9 of the Blackridge trail. It will climb 300 vertical feet up and over the hill then descend 400 feet to the city streets north of the hill. There are some great views at the top. Diamondback goes through a series of switchback meanders before arriving at Friendship Drive. There's no parking lot or official trailhead at the north end of Diamondback.
The climbing on Diamondback is fairly sustained, but not unpleasant. This trail is occasionally bumpy due to embedded rock but still technically easy.
At mile 1.5, you'll crest the ridge. Stop among the weathered granite boulders and take in the views. On a clear day, you can see north all the way to Ogden and south to the mountains east of Utah Valley.

View to the north.
After descending north around a mile from the top, you'll reach the fork between Diamondback and the Bonneville Shoreline Trail Turn hard right to continue on Diamondback. In another 0.2 miles, you'll reach the fork for Sidewinder. Turn hard left to continue descending, or keep right to take Sidewinder back to the south for a loop ride returning to Blackridge.
On Diamondback just before Friendship Drive, keep right at the trail fork to continue descending on Diamondback. The graveled trail to the left goes over a little bump on the hillside then descends north on a path that takes you between homes for about 1/2 mile.

Blackridge area map
Getting there:  First, let me caution you. Street names in this area often change as you go through a stop sign. And the names on the signs are often not the same as what you see on your auto GPS or on Google Maps. Yeah, it's messed up. But print my map (link below) and take it with you. Look carefully at the street layout as you follow my directions and you won't get lost.
Blackridge trailhead:  From the Bangerter Highway, turn west onto 13400 South and drive 2/3 mile. Turn left (south) at the Mountain View Corridor and drive about a mile. At the traffic light, turn right onto Rosecrest Road. After 1/2 mile, turn left onto Juniper Crest. (Watch out! From Rosecrest, the street signs to your right give the northbound continuation of Juniper Crest another name!) As you see that you're leaving the dense homes and are approaching a bridge across a ravine, turn right onto Ambermont Drive. (Again, caution. The continuation of Ambermont east of Juniper Crest has a different name.) Over the next half-mile, Ambermont goes southwest, then west, then turns to northwest. Now fork left on Aurora Vista. Quickly turn right onto Esher Street, then left at Ashland Ridge and enter the parking area for Blackridge Pond. The trail starts at the far end of the parking strip. (If you reach a "do-not-enter" exit from Blackridge Pond on the right and a "bozos-stay-out" sign for a private neighborhood straight ahead, you went too far on Aurora Vista. Turn around and go back to Esher Street.)
