Carlsbad Caverns, New Mexico.

These caverns are huge! I hiked down through the natural entrance and into the big room which was two miles and took a couple hours. The caverns are made of limestone, and it is a living cave which means it is still growing.












I have been in several caves before but nothing on this scale. It had all the usual formations: stalagmites, draperies, soda straws, flowstone, and popcorn.


I was surprised that visitors could tour the cave alone. I was even more shocked when I got to the end and found a gift shop and an elevator - in the cave!











I watched the bat flight that evening. Hundreds of bats flew out of the cave at the same time for their night feeding.
