Berryville - Cosmic Cavern

6386 Highway 21 North

Cosmic Cavern is one of Arkansas' hidden treasures. You will see 2 bottomless cave lakes during your 1hr and 15 minute tour. The first lake, South Lake, has had trout in it for nearly 50 years. Some trout have gone blind and most have lost their color. The bottom or end of these lakes have yet to be found.

Come see our newly discovered area, "Silent Splendor". Silent Splendor has been hailed as a must see in Arkansas. Silent Splendor houses one of the longest soda straw formations in the Ozarks measuring over an incredible 9 feet!

Don't forget your camera! There are several photo opportunities throughout the cave.

The warmest cave in the Ozarks, 64 degrees and 96% humidity, so it feels warmer than it is!

1st experience of a cavern. The cave itself was beautiful and very unique. Privately owed and operated. The tour guide lady spoke to us adults as we were children. Instead speaking educational information about the cave she named each formation as bacon, corn dog or ribs. After explaining to the tour guide that my husband was hard of hearing she made no effort to speak louder. I would love to do the after 5 tour (with the owner or the other tour guide).

We went on a tour today. Our tour guides name was Joann. Joann was very informative, fun, she also gave plenty of time to take lots of photographs and sightsee. She is also very knowledgeable in the history of the cavern. And with her Enthusiasm of the cave she clearly loves her job! Thank you for making this such a memorable experience.

This was, surprisingly enough, a good experience for the tourist type. I'm not into serious spelunking, and if you are don't go here. Still, the guided tour through the cavern was an interesting way to spend the afternoon. I'd recommend it to anyone with children, or anyone looking to kill some time. The serious cave dweller/ athlete should avoid it, but that's about it.

This was our family's first cave experience. We loved it. The walk ways are a little scary at times but it was a very beautiful cave. The tour guide was very knowledgeable and loved having our 5 and 7 year old kids on the tour. Small groups which is nice. Be prepared for a small workout, there are stairs that have to be climbed up and down.

Extremely interesting, beautiful cavern! Don't judge the inside by the rustic, not busy outside, because it is so naturally beautiful, you will love it. Not as touristy as some of the other places so more enjoyable. See it while you can!
