Arth's Corner

Arth's Corner is a lovely little singletrack trail just below Gemini Bridges north of Moab. It's only 1.5 miles long, connecting the Gemini Bridges road to the Metal Masher road. The riding is intermediate in tech requirement, but suitable for young riders and advanced beginners.

Trailhead of Arth's Corner on the Gemini Bridges road. Photos and description based on a ride by Bruce and buddies on April 13, 2011.

The trail has 200 feet of altitude change over its course. The recommended riding direction is west (the upper Gemini Bridges end) to east (ending on Metal Masher). A loop ride starting from Gemini Bridges parking and returning via the gravel road is 3.4 miles. The trail can be done as an out-and-back.

A few feet from the trailhead, Arth's connects to downhill ends of Getaway and Bull Run. Across the road from Arth's trailhead is Great Escape.

Gene takes a look into the big hole at Gemini Bridges. You aren't allowed to bike the 0.2 miles to the arches. Bike parking is provided right at the hiking trailhead.

Arth's Corner is the second segment of the Magnificent 7 epic ride. This route is 26 miles long, beginning with Bull Run. The next trail section after Arth's is Little Canyon Singletrack, located right across the Gemini Bridges from the end of Metal Masher.

Derek heads out across the slickrock. Much of the trail surface is as you see here -- easy cruising on Entrada. The La Sal Mountains form the background. In the middle background are domes of Navajo sandstone of the upper Moab Rim with the fins of Behind the Rocks at far right.


From the Gemini Bridges parking area, head east downhill. About 0.15 miles after rejoining the main road at the Y fork, the Arth's Corner singletrack forks off on the left. Keep to the right as Bull Run and Getaway join on your left. It's well marked. There are yellow paint spots on the rock to show the way. You won't get lost.

Looking back uphill. Nothing too tricky here. Nice big yellow paint spots for easy navigation.

When the trail ends on the Metal Masher road, turn right and pedal a short distance back to the Gemini Bridges road. If you're doing the little loop, head uphill on the road. If you doing a longer ride such as the Mag 7, cross the road to the continuing Little Canyon singletrack.

Gene follows the trail as we near Metal Masher.

Looking 200 feet down through the arch window.

Getting there:  From I-70 and Crescent Junction, drive south on US-191 for 20 miles (about 9 miles north of the Colorado River if you're driving out from Moab) to Highway 313. Drive 13 miles on 313 to the Gemini Bridges sign and turn L onto dirt road. (For the Mag 7 ride, start here.) Drive down the gravel road 6 miles then turn right to the Gemini Bridges parking area. There are also a few parking spots right at the new Arth's Corner trailhead on the Gemini Bridges road.
Alternate: Two miles south of the 191-313 junction, cross the railroad tracks to the Gemini Bridges road. (Note: the road will be scary, narrow, and steep path as it passes over the skirts of the hill.) Follow the road 7 miles to Gemini Bridges.
