My husband and I were married inside this cave five years ago yesterday, December 1, 2014. I went there as a kid and fell in love and it was a perfect place for us. 💕

Looking at the map at 0:14, I see that Kansas has annexed Kentucky. This will not stand!

I was there in the summer of 1988. I was young and only remember the cold and the darkness. My father was pretty into it. Mother, not so much.

I remember taking a field trip there when I was in elementary school. The whole class really enjoyed it.

I remember me my Mom Dad and brother riding this boat in the 70s and 80s

[kennethamoore]

I went there in college. It was scary and we were on a glass boat bottom

The water is pristine they don't want bacteria from human bodies to ruin it!

[danielpizana]

It is upsetting to me that I have claustrophobia and will never be able to see this kind of stuff in person. I would freak out instantly, hell, I actually had fear course through my body looking at it lol. smh.

I remember when i was 6 I spent 2 nights and 2 days in here with boy scout squad we went caving and crawled through tunnels it was awesome

Cherokee for Sweet Water is: "Ama Kanasta" I visited the Lost Sea Caverns back in 1984 when I was 15 at Summer Camp in Tellico Springs just a few miles away.They took us on a field trip to the cave and then we went to a nearby university and saw some people break dancing in the gym, the whole day was awesome and a memorable one at that because I remember while we were riding in a flat bottom boat at 8 people at a time, the tour guide gave us all dry fish food that looked like cat food into the water where 4- foot long giant blind catfish with white eyes would let me feel the sides of their skin as they slowly swam by! Where did they all go?
