This is such a cool list of incredible, mysterious sights to see in the United States that are all underground -- a top secret, government hideaway in West Virginia that was intended for use during the Cold War but was never needed all the way to an underground home in California. This is going to be fun!

6. Cave of the Crystals, Mexico
Intersecting columns of gypsum in this location recently discovered in 2000 very near Chihuahua, when water was removed from an underground chamber is named for the world's biggest natural crystals, La Cueva de los Cristales. Unfortunately, there is chatter around refilling this with water because of its temperature conditions. Near 100 percent humidity and 136-degree temperature as a result of a pool of magma (molten rock) under the cave.

5. Greenbrier Bunker, White Sulphur Springs, WV
If you live or travel in the Greenbrier resort area of West Virginia, you must stop and see the secret, hiding there since 1956. It has now been declassified, but in its day, it could have housed over 1,000 people behind its 25-ton blast doors. It was never used, but it was equipped with decontamination chambers, meeting rooms, power plant, and communications equipment. There is even a great hall for joint sessions plus meeting rooms. How big is it? Put two football fields together.

4. Forestiere Underground Gardens, Fresno, CA
You will be amazed at this location built by Baldassare Forestiere, a Sicilian immigrant. Attempting to re-create the catacombs from his home. He spent 40 years with a builder and gardener who dug out 10,000 square feet of space for a chapel, rooms and a freaking fishing pond! And, all they used to dig were farming implements. It's a cool pitstop from the heat of the sun, and you can see the blooming fruit trees as they climb to the skylights for life.

3. Coober Pedy, Australia
An underground hotel, restaurants, and art galleries wait for about 4,000 Aussies in the event of an Apocalypse. Originally a World War I mine cave for opals and used by weary soldiers looking for a safe place to rest. You can stay in a hotel, enjoy art galleries, go to church, and dine all underground. You can play grassless golf too and view the same desert landscapes seen in Mad Max Beyond Thunderdome.

2. Nevada National Security Site, Las Vegas
Just a short trip from Vegas, find ghost towns, and nuclear bomb tests leftovers. But if you're wondering why this is on our list, under the ground, you'll see craters that have been sealed via the atomic testing hellfire's left from the hundreds of tests performed during the Cold War. These tests turned sand and rock to liquid, and they now appear like bubbles made from glass. These phenomena are not visible until there is a cave-in. The National Atomic Testing Museum is the meeting spot to kick off public tours, which only happen once each month.

1. The Cavern Suite, Grand Canyon Caverns, Arizona
If you're looking for peace, quiet, and dark as night, you will be the only life in this creepy cave. So, bring up to five of your friends to rest up 220 feet below ground with zero humidity. Don't worry, fresh air comes in via the Grand Canyon, over 60 limestone filled miles away, it is the deepest motel room in the US.
