Located outside of Grand Junction, Colorado, the Colorado National Monument is a unit of the National Park Service that is worth a visit. We spent a few hours driving along the 23-mile Rim Rock Drive, stopping for a couple of short walks along the way. The first stop was for Otto's Trail, which was less than a mile round trip. At the overlook, you have excellent views of canyons and Independence Monument. We then drove to the Upper Monument Canyon to see the Coke Ovens; this walk was a little over a mile round trip. We even saw a big horn sheep crossing the road, so look out for wildlife! There was more to see that we'll have to go back for on another visit. Highly recommended.
