Bicycles are permitted on all paved and unpaved roadways within the park but not on any of the trails. There are no bike lanes or paved shoulders. Cyclists must ride single file at all times with the flow of traffic. Cyclists should expect large buses and RVs on the road. Signs warn drivers that bikes might be present and to keep a minimum of three feet from all riders, but cyclists should remain very alert to passing vehicles.
There are many options for riding bikes outside the park. Moab is surrounded by mountain biking trails of every difficulty level, from dirt roads to technical singletrack. Popular road rides abound, as well. A paved bike path connects the gateway community of Moab with the entrance to Arches, and continues along US 191 to UT 313 (which leads to Canyonlands National Park and Dead Horse Point State Park).
