The Gold Bar Rim Singletrack (formerly known as the Blue Dot trail) is a technical route along the edge of the cliffs north of Moab. The trail follows the cliff edge four miles from the Gold Bar Overlook to the intersection of Poison Spider with the Portal Trail. This is a double black diamond expert-level trail. Riding season is April through November.Note that there is a Gold Bar Rim Trail that's a 4x4 route climbing from the Gemini Bridges Road to the overlook. And there's a Gold Bar Singletrack that climbs from the bottom as an alternate to the lower portion of the road. When discussing these trails, be sure you're talking about the right route!
Don't backtrack to the more-prominent route 100 feet down the hill. That's Golden Spike and it's not the trail you want.
The path is generally downhill -- although it won't seem like it -- with about 150 feet of elevation loss over the four miles.
The return via Poison Spider and Golden Spike (the Grand Tour ride) is very strenuous and longer than you'd think. And I swear there's more climbing, rougher rock, and steeper slopes every time I hit Golden Spike. Don't underestimate it. Instead of the Grand Tour, consider descending the Portal Trail and taking 278 to the paved bike path. Connect to Highway 313 for the ride back to the top. I've done this a few times, and it's a long but reasonable commute. And there are calories and drinks at the 191-313 junction.
Great ride for experienced expert riders in good condition. Highly technical and very difficult aerobically. Lots of challenges, incredible views. A ride like none other in Moab.

Take the Gemini Bridges Road 4.5 miles from Highway 191 then turn left at the Gold Bar Rim road. If you're driving, find a parking spot here. Head uphill on the Gold Bar Rim Road then turn left onto the Gold Bar Rim ST. Follow the paint until you rejoin the Gold Bar 4x4 route. At the cliff edge, head right (southwest) on the slickrock.
To leave a shuttle at the Poison Spider trailhead: On 191 at the bottom of the canyon (just past the old tailings pile), turn west onto U-278 (also called Potash Road). Drive 6 miles then turn right up a short dirt road with a sign that says "Dinosaur Tracks." There's a bathroom at the parking area.
