There is a special place in my heart for southern Indiana. The Ohio River creates the southern border between Indiana and Kentucky, and the state is full of rolling hills and luscious greenery.
Eldorado Canyon is one of Colorado's many state parks. It is known for its hiking trails, rock climbing opportunities and picnic areas along South Boulder Creek. For $8 you can purchase a day pass that will give you access to over 500 rock climbing routes, and 11 miles of hiking trails.
The Black Canyon was carved from the Gunnison River starting two million years ago. It has weathered this stone away into a canyon, up to 2,400 meters at its highest point.
