  • The caves are very cool! Our tour guide was younger but spoke clearly and effectively to the group. It was really neat to see all the stuff they showed us. The gift shop was also great and affordable....  more »

  • Easy to find. Affordable, clean, professional, very knowledgeable staff. Enjoyed the tour! Can't wait to take the rest of my family at an older age. Nice gift shop with enough small, affordable items for children. Mini golf on site. Picnic shelter with plenty of tables. Small play ground with equipment. Great for a well planned trip with packed lunches. There is also a great place to eat just down the road in Harmony called On The Crunchy Side.
  • On a hot summer day this is a very "cool" way to beat the heat. Amazing beauty underground. It's more than a cave tour. Above ground they have a very nice picnic area, you can pan for gems and play a great family friendly round of mini golf.
  • This cave can be summed up in one word: WOW. It is simply amazing, with a beautiful waterfall as only one of the wonders inside. We visited a few days after it rained, and the rushing water was spectacular to both hear and see. A few notes: It is 250 underground at the end. Walking down into the cave is relatively easy, with several stops on the guided tour. However, you come back out the same way, except without all of the stops. There are several staircases along the tour route, and some of our fellow visitors felt the need to stop a few times along the way to rest. Remember to bring your rescue inhaler if you use one!
  • There's about an hour tour through the caves led by a guide. They do warn if you are not good with confined spaces or stairs, not to go; this is for good reason. The trails in the cave get quite narrow in parts. There's also about 250 stairs to go up and down. The most you do at once is about 100, which are as you are going back up to the top. Be prepared also with a jacket, as the cave temps are less that 50 degrees. Also be sure to have shoes with good traction, and ok to get dirty. The trails in the cave are wet and slightly muddy (enough to splash up on pants). The formations in the cave are very cool. The waterfall you can only see from the top but very nice as well.
  • Amazing waterfall inside! Great tour. Hard to believe you can find something like this in southern Minnesota under fields.
