It's not something I would go back to if ever in the area but both of my kids (12 & 15) both thanked me for letting them go. The only thing we did was the tour so I can't say how the food is or how the "mine" is. I do know that the earlier you come, the less time you have to wait. There was one reviewer thinking that the wait was long so you would spend more money. It's not their fault that a lot if people come to the cave wanting a tour. For your safety, they only allow 20-30 people per tour and one starts every 20 min. We arrived about 2 hrs after they had opened and only waited 30 min. But my advice is to go see about tickets right after arriving, then if you have a wait, you can plan your other activities accordingly.

Neat family attraction. Very nice people and great guide. The tour is interesting and has a short boat ride on the lake. The walk is a bit steep at times but is manageable in good shoes. Small children seem to lose some steam and many were being carried back up the walkway. Very low light inside but after your eyes adjust no big deal. There is a little candy store and gift shop and a bbq restaurant on location. We didn't eat here but went about 5 miles up the road to the town of Sweetwater. Great little downtown with lots of nice antique shops.

This was definitely a sight to see. The cave tour lasts about 45 minutes and then you sail the cave lake in a slow moving motorboat. The cave was ok (though nothjng unique, there are bigger and better) but the lake is the main attraction. The tour was interesting, and the tour guide, Brian, was very informative and entertaining. One thing I didn't like, though, was that efforts are not made to preserve the cave in its natural state. For example, there are fish in the lake, non-native species that are still there for no apparent reason, and when going into nature, I want to see the real thing. Overall, though, you won't regret visiting.

This attraction has a two part review:

1) the cave is amazing and the underwater lake is breath taking. It is great for the nature lover and kids. Lots to see and learn.

2) the ticket price is a little steep. The tour guide didn't really keep up with the group and if you weren't careful, well you were left in the dark. The boat ride on the lake was all of 5 minutes long. To be the wonder of the cave, one would think the boat ride would have been much longer. The gift shops were a little over priced and very outdated.

We drove two hours to get there, and were extremely disappointed!!! Our tour guide Collin seemed extremely bored with the very minimal information he shared. We went to another cave in Townsend and it was such a better tour with so much more information. The boat tour is a joke. The rainbow trout aren't even natural to the "lake" and the "glass bottom" is all muddy and there is nothing to see. Boring and short. We were so disappointed we just left without the thought of tipping our guide and we tipped our sweet guide 10 dollars yesterday! So bummed we got sucked into this LAME tourist trap. I have very mild asthma and the climate changes bothered me a little. Be warned about the steep hike from the lake about twenty minutes if the tour is sitting at test stops. The cave is cool but it is so commercialised (at the first rest stop he encouraged us to like their fb page instead of answering questions or giving us more information about the cool formations around us). You are better off finding another cavern with guides who care.
