Colorado National Monument loop via Rim Rock Drive

While the 22.5-mile drive itself can be cycled in about 1 hour 41 minutes by very fit cyclists, it's recommended to allow at least three hours for the full 33-mile loop. This gives you time to enjoy the breathtaking views, stop at overlooks, and take photographs without rushing.

No, the Colorado National Monument loop via Rim Rock Drive is considered a strenuous and challenging road ride. It's best suited for fit cyclists with some climbing experience due to significant elevation changes, including over 2,000 feet of gain, and steep sections. The high elevation and low humidity also add to its difficulty.

You can start from either the Grand Junction or Fruita entrance. An insider tip for tackling the climbs is that the ascent from the Grand Junction side is generally tougher and shorter (about four miles), while the climb from the Fruita side is more gradual and longer (about six miles). Consider your preference for a steeper, quicker climb or a more sustained, gradual one.

The route features a generally smooth paved surface, winding along dramatic canyon rims. You'll pass through three natural rock tunnels (two on the west side, one on the east), where lights are required for safety. The road is narrow with steep drop-offs in many sections, so caution and riding single file are essential. Expect significant elevation changes with steep climbs and long descents.

The route offers spectacular views of towering red rock monoliths, sheer-walled canyons, and sweeping desert vistas. You'll encounter a unique 'moonscape-like' environment with sandstone cliffs and diverse rock formations. Notable viewpoints include Coke Ovens Overlook, Grand View, and panoramas of areas like Devils Kitchen and Independence Monument. Don't miss the View of Colorado National Monument itself.

Wildlife sightings are common along the drive. Keep an eye out for bighorn sheep, eagles, chipmunks, rock squirrels, and coyotes. The diverse landscape supports a variety of desert fauna.

Yes, cyclists must pay an entrance fee to enter the Colorado National Monument. You can find current fee information and details on passes on the official NPS website: nps.gov.

The best seasons to ride are spring and fall. This helps you avoid the intense summer heat, which can make the strenuous climbs even more challenging. The weather during these seasons is generally more pleasant for cycling.

Dogs are generally permitted in the Colorado National Monument, but with strict regulations. They are allowed on paved roads and in developed areas like campgrounds and picnic areas, but not on hiking trails or in the backcountry. They must always be on a leash no longer than six feet. Given the nature of this road cycling route, your dog would need to be in a trailer or otherwise contained if you bring them.

Given the strenuous nature, high elevation, and low humidity, it's essential to bring plenty of water and snacks. Lights are required for passing through the tunnels. Sunscreen, appropriate cycling gear, and a repair kit are also highly recommended. There are limited facilities along the drive, so be prepared to be self-sufficient.

Facilities are limited along Rim Rock Drive. You'll find restrooms and water at the Colorado National Monument Visitor Center, located near the Fruita entrance. It's crucial to carry sufficient water for your entire ride, especially given the challenging climbs and desert environment.
