Pikes Peak: Katharine Bates wrote "America the Beautiful" after taking a wagon and then a mule ride to the top of Pikes Peak. Today you can ride in a train on a cog railway to the top for the same see-forever views of Colorado Springs to the Kansas border.

The U.S. Air Force Academy: Visitors from all over the country come to this mountainside campus to see the cadets marching on the parade ground and learn more about the Academy that trains the future leaders of the Air Force.
