Take An Adventurous Day Trip To Grand Canyon Caverns, The Deepest Cave In Arizona

Next time you find yourself on the Mother Road, don't pass up the quirky green dinosaur in Peach Springs. He stands guard over Grand Canyon Caverns in Arizona, a bucket-list-worthy destination that takes visitors nearly 300 feet below the earth's surface. Marvel at unique cave formations, enjoy a meal underground, and even spend the night in a subterranean motel room! Check it out:

Located along historic Route 66, these are the largest dry caverns in America.

A motel, diner, gift shop, old-fashioned gas station, and several other attractions make this a one-stop vacation the entire family is sure to enjoy.

An elevator takes visitors nearly 300 feet below the surface, where tours of varying difficulty are offered.

Paved walkways with handrails make the regular tour accessible to almost everyone, and those craving more adventure can venture off-trail on the Explorer Tour.

The walls are studded with cave formations, from the 'usual suspects' like stalactites and soda straws to rarities such as these "teacup handles."

No matter which expedition you choose, rest-assured your eyes are in for a real treat.

Otherworldly entities come out to play all year long in the caverns, and the nightly Ghost Walk lets you get up-close-and-personal with them.

Everyone brave enough to embark on the tour is given their very own EMF meter to ensure no paranormal activity goes undocumented. This underground labyrinth has seen its fair share of death, so expect at least a few extraterrestrial encounters.

Breaking records all around, the caverns are also home to one of the world's deepest subterranean restaurants.

Cavern Grotto is among the most unique dining experiences you'll ever have, situated 210 feet below the surface. Chow down on burgers, steak, and other hearty classics while taking in the rugged, 65 million-year-old surroundings.

Yet another thing that sets Grand Canyon Caverns apart is its underground motel room.

Spend the night in the Cavern Suite, if for no other reason that to say you've slept in the largest, oldest, deepest, darkest, quietest motel room in the world.

Equipped with plenty of creature comforts to make you feel right at home, this anything-but-ordinary accommodation is surprisingly cozy.

It sleeps up to eight guests, and features a library of old books and magazines, working record player, and TV with a vast selection of classic DVDs. No matter how it looks, you won't exactly be "roughing it." Don't worry—there's ample aboveground lodging for the less adventurous types.

If tying the knot underground has always been a dream of yours, look no further. Weddings and other events are often held in the caverns' underground stage, complete with theater seating.

What a memorable way to say "I do!"

Doomsday preppers, bring a pad and pen with you on the tour.

You'll want to take notes—clearly someone down here knows what they're doing, as the emergency stockpile has enough resources for 2,000 people!
