Are you the kind of Hoosier who’s always looking for the next big adventure? What a coincidence. Us too! Sometimes, life is all about the next big adventure, and Indiana is the perfect state for doing exactly this. Take, for example, this totally epic cave boat tour in Indiana: it’s the perfect way to kill an entire afternoon, and it’s an awesome adventure from start to finish. As long as you’re not claustrophobic, you’ll absolutely adore this astonishing Midwestern adventure. How awesome is that? Not only are there caves in Indiana, but you can tour them by boat. Talk about awesome.

Enwrapped within the beautiful boundaries of Spring Mill State Park are a formation known as Twin Caves, a gorgeous geological wonder just waiting to be explored.

As far as caves go, they're technically nothing special, though they're what's known as a Karst Window (which occurs when the roof of a cave collapses and exposes the groundwater below the surface.
These cave boat tours in Indiana are probably the most popular attraction within the park, and it's obvious as to why.

....like, come on. How ridiculously cool is this? You get to tour a cave... in a boat... and during the process you'll get to experience true darkness.
It's oddly peaceful, really, unless you've got a fear of the dark (or are claustrophobic).

In that case, this is probably NOT the attraction for you. Feeling brave, though, and up for a little adventure? We think you should conquer your fears and give it a shot.
