Navigating rides on major paved roads around the mountains is easy. All that is really needed is a Colorado state highway map and a relatively short
Navigating rides on unpaved roads is a little more complex because many of them aren't shown on the normal highway maps and sometimes they are poorly marked.
Unpaved roads can include smooth well-treated surfaces, gravel, deep gravel, sand, rock, bigger rock, gradual rises, and steep climbs.
Quite a variety, requiring more planning time and more detailed maps and other resources.
