I highly recommend the overnight adventure. It is awesome! Staff is great, adventures are great & food was good too. Extra shout out to the staff . They did a great job & made it fun. :)

Longest known underground river in the United States at 21 miles. Offers boat tours 9 am to 5 pm leaving on the hour.

If you go on the overnight adventure bring wool socks for sleep, knee & elbow pads & headlight are a must for the wild caving .

Tours leave exactly on the hour. We called and said we would be there by 4, but when we got there , they sent the tour guide home for the day even though they told me not to worry on the phone.

Excellent place! Love the underground tour ! Make sure to bring a jacket though. :)

Great cave boat tour . One of the better things to do, if you're trapped in S. IN

Bring a jacket or sweatshirt. It's 52˚ in the cave year round.
