Blackridge trails
The Blackridge trails start at Blackridge Pond in Herriman. There are three major trails:  Blackridge, Diamondback, and Sidewinder. Blackridge is still being extended in July 2018 but is open for riding up to the trail-construction area. This trail guide is for a short lariat ride with around 400 feet of total climbing, suitable for beginning riders.
Trail conditions, alignments, and connections will change. Use this guide at your own risk. Copyright 2018 UtahMountainBiking.com

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: Get onto Juniper Crest as above. 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.)
