With some great day trip options available in the surrounding area, having your own car makes sense. Without one, it’d be much more difficult to enjoy everything that Hannibal, 25 miles away, has to offer. Mark Twain Cave ought to be at the top of your to-do list here. Jim’s Journey: The Huck Finn Freedom Center and Mark Twain Cave and Cameron Cave are must-see attractions too. Nauvoo is another popular option. It’s 35 miles away and offers an array of fascinating things to see and do. Historic Nauvoo, Nauvoo State Park and Joseph Smith Historic Site are only the start.
