NEW BICYCLIST RESTRICTIONS IN TUNNEL! See blue text below.
Bicycling the Rim Rock Drive is popular and challenging. To insure your safety, please share the road with drivers and follow these regulations:
By itself, the Rim Rock Drive is just 23 miles long, but it joins with connecting roads outside the monument for a grand loop of 33 miles. Whether you decide to ride the entire circuit or only a part of it will depend on how much time you have and how fit you are.
For the grand loop, the aggregate climb for a complete trip is 2300 vertical feet, due primarily to the steeper grades just inside either entrance. Allow three hours.
Off-road mountain biking is not permitted in the monument, but several adjoining areas are ideal for it.

Each Independence Day, local climbers scale the iconic Independence Monument in Colorado National Monument and raise an American flag on top. This tradition dates back to early park promoter John Otto, whose route up Independence Monument climbers still follow.
