We are took a couple of tours here. First, we took the King's Palace Tour. This was a paid tour and we had to reserve tickets online before we arrived. After we took that tour there was a free walk on your own tour that we took called the Big Room Tour. Both were amazing and on the King's tour we had a great guide. Probably the most amazing underground cavern in the world. The one truly amazing difference about the Carlsbad Caverns and all other underground caverns in the world - it was not created by running water.

Here I am holding up the railing.
I know you can't tell from this but this thing is about 40 feet tall.
The natural formations of this cave were beautiful and strange at the same time.
Here is the entrance to the Natural Cave and it is world-famous for being the location to watch the millions of bats come out at sunset each day. They were hibernating while we were there.
