Reviews Summary

The staff are noted for their friendliness and efficiency. Some visitors mention the physical demands of the stairs, advising preparedness for the climb.
"A must see! A stunning cave, informative tour and more! We stopped here with a larger group, the cave staff handled us great even moving around start times to get both of our tours started earlier than scheduled. The cave has some great features and our tour guide was excited to tell us all about them. He was knowledgeable and personable. Even our 3 year old had a great time. Above ground they have a mini golf course and playground to keep everyone occupied prior to their tour."

"This was a Minnesota Bucket List place to go. We were told to buy our tickets ahead of time if we wanted a specific time locked in. Otherwise, you could go and wait for the next available opening. They have a nice little mini golf course to play on to pass some time. We got here an hour early just to play it before we saw the cave. Both events here are good ones. Audra showed us with her light that the stone glows in the dark. Pretty cool. Highly recommend this adventure. Enjoy…"

"We enjoyed our visit to see these amazing caves in Harmony, Minnesota. We ordered our tickets on arrival. We looked around the interesting gift shop while waiting. Some others with young children enjoyed the mining activity or mini golf outside. The tour guide was very knowledgeable and gave us time to enjoy the cave and take pictures. Our group was small enough for questions to be answered and everyone to see the cave and the underground waterfall. There are steps and about a mile walk involved. If you can physically do that, it is worth it to see this natural wonder of God's creation! They have many interesting rocks, lamps, cookbooks, food items, and clothing to purchase for gifts and personal enjoyment on your way out."
