Southern Indiana has lots of hills and forested areas, including the Hoosier National forest. The Great American Rail-Trail mostly goes through the upper third of the state, however, so you miss that and are mostly in the corn belt section of the state. Its very flat and mostly farm land. Which is likely why the railways were built on that route anyways.

I personally can find flat farmland quite beautiful, but I can imagine biking through it for days might get dull.
