Did you know that beneath your feet in the Hoosier State there is an entirely different world? It’s true! Stretching hundreds of miles beneath the earth are more than 4,000 caves in Indiana alone – and those are just the ones we know about! Several of those caves offer some really interesting experiences, and we found one cave that offers two different spellbinding tours, both of which are absolutely worth checking out. You can do just one, or you can do both – no matter what, if you’re even a little interested in geology and caving, these tours will blow you away. Visit Marengo Cave, in Marengo, Indiana, for amazing cave tours in Indiana you won’t soon forget.

Your two options for tours at Marengo Cave - and we recommend both! - are the Crystal Palace tour and the Dripstone Trail tour.

Each has its own pros and cons, though honestly, it really is kind of difficult to think of any cons to exploring an amazing, mature cave system in Indiana.
The Crystal Palace Tour is shorter, and it's jam-packed with awe-inspiring and curious formations.
Marengo Cave
It only takes about 40 minutes to complete, and you're sure to learn some amazing things along the way!
The Dripstone Trail is longer, more complicated, and even MORE rewarding - if that's even possible.

It takes an hour to complete, and along the way, you'll see fascinating things like soda straw formations, stalagmites, and a famous part of the trek known as Penny Ceiling. Here, there's been an offbeat tradition for decades: folks have been throwing coins at the sticky mud of the cave ceiling in this spot, and the coins stick! In 1999, the ceiling was cleaned through many painstaking hours in an effort to remove literal decades' worth of stuck coins, ensuring that guests can continue to toss coins up there for decades to come.
