The Utah Border Sign โ Utah Border Marker loop from Mack offers a deep dive into the unique desert landscapes of the Colorado-Utah border, characterized by vast, open vistas and minimal human presence. You'll navigate a mix of hard-packed dirt and chunky gravel, with some sections of dilapidated road that feel more like raw terrain than groomed trail, all while keeping an eye out for desert flowers in spring or local wildlife like antelope.
This moderate 19.6-mile (31.5 km) gravel biking route involves 878 feet (268 metres) of elevation gain and typically takes about 2 hours and 26 minutes to complete. Be prepared for self-sufficiency, as services are non-existent; carry ample water and supplies. Spring and fall are the prime seasons to ride, as summer heat can be extreme and dangerous.
This remote loop provides an excellent training ground for longer desert gravel grinders, offering a true sense of solitude away from crowded areas. The opportunity to cross the state border on two wheels adds a distinct charm to the ride, showcasing the surreal views and diverse flora of this high desert region.

A must do when in Moab and for sure the best trail if you want to convince somebody to buy an ebike. Very physical. I have the feeling the altitude is counting twice in Moab.

The trail isn't called "Slick Rock" for nothing. Inexperienced people will reach their limits in various places on the steep rocky passages and will find it easier to descend...

This point is a pretty popular group ride destination in the area. You can ride the quiet country roads out to the Utah boarder. There only thing really telling you where you are is the spray painted wood sign. The final stretch of road before you get to the boarder isn't paved, but it's not gravel. Just a dilapidated road that has been left to the elements.

Slickrock Trail is a classic Moab trail on the sandstone. Slickrock was the term given to the rock by early cowboys noting that their horses' hooves would slip on the rocks when they were wet. There is a lot to explore here. You'll also see Jeeping nearby on similar rock formations.
