La Sal Mountain Loop State Scenic Backway

Area Status: Temporarily Closed

The Central Federal Lands Highway Division (CFLHD) of the Federal Highway Administration, in cooperation with the US Forest Service (FS), the Bureau of Land Management (BLM), and San Juan County is proposing to rehabilitate and widen 2 segments of road, totaling 12.12 miles along La Sal Mountain Loop Road. This project is scheduled for construction beginning in the spring of 2024 to fall of 2025. Construction has started as of May 20, 2024, get the latest updates and access information here:

From the alpine ridges of the La Sal mountains to the red rock desert and sandstone pinnacles of Castle Rock, this backway is an adventure! You will see mesas and buttes used in movies and drive past steep laccolithic peaks that often serve as the backdrop in photographs of the famed Delicate Arch. This 60 mile route is paved and starts about 8 miles south of Moab off US-191 and loops through the mountains down to Castle Valley and SR 128 where it follows the Colorado River back to Moab. It takes about 2.5 to 3 hours to complete this drive. The narrow winding road, while suitable for passenger cars, is not suitable for large RVs or trailers. There are no services available along the route so make sure you have all the gas, food, water, and other supplies you may need for at least a few hours.

The La Sal Mountain Loop Road brochure is available for download.
