Musselman Arch is located in Canyonlands National Park. Accessible only by a rough dirt track, it is best reached by a high clearance vehicle, but can also be seen via biking or a long hike. While Technically a natural bridge (it was called Little Bridge in the past), it is 5 feet thick, 6 feet wide and 187 feet long, while being 300 feet above the ground. It is hard to find country that is more impressively wild than Canyonlands.
To get to Musselman Arch, drive north from Moab on Hwy 191 and turn on Hwy 279 (Potash Mine Rd) – it is about 10 miles total going from here to the arch. Follow the paved road to the potash mine where it becomes a 4WD road that should be navigable for most high clearance vehicles. Go past the evaporation ponds (if filled, they are of the deepest blue) and into Canyonlands National Park. The road will meet the White Rim Trail – make a left and the arch is about 2.25 miles. A Day Use Permit is required to enter the canyon in this way.
As you make your way on Hwy 279, make sure to see the Petroglyphs along the Colorado River. If you have time, stop at the trailhead for Corona Arch and make that 3 mile round-trip hike – it is a great arch. Continuing along Hwy 279, watch for Jug Handle Arch, which is right along the highway.
You can also make the trip to Musselman Arch by taking the Shafer Trail from Canyonlands Island in the Sky district down the iconic Shafer Trail which starts just before the entrance station. Again, high clearance is recommended. Don’t take the Shafer trail down if you are not comfortable with extreme switchbacks, long drop-offs and no guard rails. This road is not for the faint-of-heart or inexperienced driver. The arch is about 5 miles going in this direction. A loop from Potash Road to the Arch and then up Shafer Trail is a logical route.
The hike from the parking area is only about 300 feet on mostly level ground. You are on about the same level as the arch when you approach it.
