The Utah Border Sign – 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.
