The preztels at the bottom of Carlsbad Caverns aren't that bad.
But it's freaking weird to find a food court 754 feet below the surface of the earth in a natural wonder.
The Caverns are simply amazing. As you walk down the 1.5 mile natural entrance it gets cold, dark, damp, and smelly (we're told it's a rare combination of bat pee and mineral deposits). Once you get down there, it's quite a sight.
The Big Room alone can hold 14 Astrodomes, and in total, there is 31 miles of cave. So the 3 miles we did barely scratched the surface. Unless you're a seasoned spelunker, you've never seen anything like geology of Carlsbad. Each turn reveals a formation more bizarre, rare, and alien than the one that just blew your mind.
One major caveat is that no photos can do this place justice. The low light creates problems, but even the best photographer couldn't capture the feeling of being in Carlsbad Caverns.
