County Road 49 is another great, isolated gravel road in the far northeastern corner of Colorado. This particular road skirts the edge of the Pawnee National Grasslands, a protected area with a wide variety of prairie plants and animals. You get great views of the grasslands as well as the mountains to the west as you ride on this generally well-maintained gravel road. Like all of the roads out here, while conditions can vary, it is doable on a road bike, but you might be more comfortable on a dedicated gravel bike, or at least one that can run 28-30mm tires at minimum. Cell service is a bit limited out here, so plan accordingly.
