Fancy spending the night in what is described as the “oldest, darkest, deepest, quietest, and largest suite room in the world”? Well, as of 2010, now you can at the Grand Canyon Caverns! The only room in the caverns is 22 stories down and over 65 million years old! Tours of the caverns depart every half hour daily and last 25 minutes.

Interestingly, during the 1962 Cuban Missile Crisis, the US government stored enough food and water rations in the caverns to support 2,000 people for up to two weeks. These supplies are still there to this day and can be seen by visitors!

“For me this is one of the neatest places on the Road. With so much kitsch out there, Grand Canyon Caverns is refreshing in that it's more original than many places without the corniness. I've stayed in the motel and it's clean and comfortable if not fancy. It's also QUIET!"

"I awoke about 2am and wandered out to the deserted road and just sat there for an hour or so soaking up the solitude. It even had a bit of a post-apocalyptic feel. Along this stretch of the Road, many previous alignments can be seen if you're a history buff, and don't forget the Burma Shave signs!”
