Indiana might not be the first place that comes to mind when you think of natural wonders, but the state is home to a surprising number of hidden gems. From one of the best state parks for fall foliage to the underrated Warren Dunes State Park, the Hoosier State gives visitors plenty of reasons to get out and explore. Cataract Falls is arguably one of its most impressive natural features – located along Mill Creek, the landmark features two sets of waterfalls along with a charming covered bridge.
