Travel on Rim Rock Drive

Colorado National Monument's Rim Rock Drive is one of the most spectacular drives in the United States. Redrock canyons, crisp blue skies, and verdant green juniper splash fantastic views along the way for motorists and bicyclists. The road was built in the 1930s by the Civilian Conservation Corp. Admire the craftmanship of the stonework walls along the roads and overlooks. The road can be challenging as it is narrow, and steep in some sections with sheer drop-offs. The road has no shoulders, so bicyclists and vehicles must share the road. Use caution when on tight corners and hills. On the east side of the monument, motorists may encounter large trucks that use four miles of the monument's roadway to access the community of Glade Park. As you travel through this landscape of mesas, canyons and pinyon/juniper forests you may catch a glimpse of resident desert bighorn sheep.
A few things to keep in mind for a safe visit:
- Use your headlights in all tunnels.
- Obey traffic laws and speed limits.
- Do not attempt to proceed around bicyclists unless you have a clear view of oncoming traffic and a safe passing distance. Do not pass in tunnels or on turns.
-
When passing bicyclists, please allow at least three feet of clearance between your vehicle and the bicyclist.
-
Check carefully for bicycles, pedestrians and vehicles before pulling out onto the road from pullouts.
-
Allow other motorists and bicyclists to pass if you are obstructing traffic and there is a safe place to pull over.
-
Remember that bicyclists have all the rights and responsibilities of any vehicle.
