INN – RESTAURANTS – TOURS
The story of the Grand Canyon Caverns’ formation starts 345 million years ago, at the bottom of an ancient sea.
The Gateway to Supai
Welcome to the Grand Canyon Caverns & Inn, a vintage motor inn along historic route 66, the perfect launching pad for your Supai adventure, one or two day rafting trips and offering tours of the largest dry caverns in the United States, home to the famous caverns suite and now featuring “The Grotto”
The Grand Canyon Caverns is located along Route 66 in Northern Arizona. These are the largest dry caverns in the United States, located 200 to 300 feet below the surface, and accessible via our exploration elevator. Located in the middle of 3,000,000 acres of the most unspoiled land left in the world, we offer clean air, clear skies, open prairies, and a refreshing change of scenery from the urban world. We feature cavern tours that are easily accessible along paved walkways with handrails and for the more adventurous, off-path ‘Explorers Tours’.
The Grand Canyon Caverns is close to everywhere and yet a complete change from your urban or suburban world. We are six hours from southern California, 2.5 hours from Phoenix or Las Vegas, and 1.5 hours from Laughlin, Lake Havasu or Williams.
We are 800 acres held in trust for the world these past 80 years at an elevation of 5,500 feet on a beautiful plateau with the largest dry caverns in the united states 200 to 300 feet below the surface.
Rooms
Imagine, if you can, spending the night in the oldest, darkest, deepest, quietest, and largest suite room in the world. Imagine, 220 feet below ground, in a cavern that took 65 million years to form, in a room that is 200 feet wide, 400 feet long with a 70 foot ceiling.
Cavern Grotto
An Underground Dining Adventure
The “Cavern Grotto” is open for business! Our brand new, deep underground cave restaurant, the Cavern Grotto is now taking reservations. Now is the time to reserve a seat for one of the most amazing dining experiences possible!
To get to this restaurant, you’ll need to take an elevator. You’ll be taking it down—21 stories down—into a 345-million-year-old cave network that stretches 60 miles to the Grand Canyon.
