If you live in the Indiana, Ohio, or Illinois area Clifty, Hoffman, and Tunnel Falls Loop in Clifty Falls State Park is one of the best hiking spots nearby!
You start by parking at some of the many trailheads and head down the stairs to the start of the trails. From there you can follow your map to the different difficulty trails! They people working the gate are very helpful and can guide you to anywhere you want to go.
This 7 mile loop takes you by 3 waterfalls and is a relatively longer loop compared the others you'll see on your map. But, it takes you through a large portion of the park, so you'll get to see plenty!
Added bonus, the park is extremely dog friendly. If this loop is a little too long, there are several different difficulty levels which makes Clifty Falls State Park a great destination. There are caves and waterfalls to explore and great views of sandstone and historical structures.
