Especially in Arkansas. It's a really beautiful state. There is a bunch of other natural beauty to see like hot springs and cave tours. Our family has vacation in Arkansas quite a bit.
Blanchard Springs Caverns in Arkansas are truly a site to behold. Pictures cannot do it justice. And I have been to many well known caverns throughout the world to compare.
As far as a cave that you can simply take an elevator down to and walk through on paved sidewalks, it is one of the best in the world. (There are also other portions for the more adventurous. Some that are completely underwater and require scuba gear.)
