Picture this: you step into an elevator somewhere along historic Route 66, press a button, and descend 21 stories into the earth — only to emerge into a dimly lit ancient cavern where your dinner is waiting. The Caverns Grotto sits 210 feet below the surface of Grand Canyon Caverns in Peach Springs, Arizona, and it is almost certainly the most jaw-dropping place you’ll ever eat a meal. Hidden from the everyday diner, it caught the attention of Time Out magazine, which named it one of America’s coolest secret restaurants, landing at No. 6 on their list of the best hidden restaurants in the U.S.
The Grand Canyon Caverns were created over 65 million years ago, formed within the limestone that was once the bottom of an ancient inland sea that divided North America. Walter Peck first stumbled upon the cave in 1927 on his way to a poker game, and mistook the iron oxide and selenite crystals for gold and diamonds — so he bought the surrounding 800 acres. Today, that lucky detour has become one of Arizona’s most unforgettable destinations.
What Makes The Grotto So Special
The Caverns Grotto restaurant sits perched on a platform overlooking the vastness of the main chamber — it’s like having dinner on the observation deck of nature’s own Empire State Building, except instead of looking out, you’re looking in. Reservations are required, and the restaurant exclusively serves four tables at a time, with a dining area that features a natural ambiance and 360-degree views of the caves, and virtually no outside noise other than the sound of conversations.
The main entrees are made in the restaurant above ground and delivered in buckets down the elevator into the cave, where a pulley system carries them up to the platform. It’s dinner-as-theater — and the performance never gets old. The four-table eatery offers simple American comfort food that makes a not-so-simple voyage to your table. Think hearty classics like French dip sandwiches, prime rib, burgers, steaks, and taco salads, with beer and wine available to round out the experience. The meal includes two drinks, a salad bar, dessert, and a cave tour — making it a full underground evening, not just a meal.
The 16-seat eatery is integrated into the largest chamber of the 345-million-year-old cave system, which extends 60 miles to the Grand Canyon. Few restaurants can claim their dining room predates dinosaurs by hundreds of millions of years — the limestone cave system formed during the Mississippian Period, when this entire area sat beneath a shallow sea, and ancient marine life left behind the building blocks for these spectacular formations.
The Cave Tours: Worth Every Step
During the Cuban Missile Crisis in the 1960s, the U.S. government designated the caverns as a fallout shelter, stocking them with supplies for 2,000 people — some of which are still visible today. That’s just one of the many wild stories brought to life during the guided cave tours. The popular 45-minute guided tour takes you 200 feet underground via an elevator, with paved walkways and handrails making the experience accessible for all ages — and for the more adventurous, explorer tours involve crawling and climbing through unexplored sections of the caverns.
The tour reveals stunning formations along the way, including areas named “Winter Crystal,” “Cave Coral,” “Grape Clusters,” “Halls of Gold,” “The Devil’s Den,” “Snowball Palace,” and “Mammoth Dome,” along with fossils and ancient waterfalls. Unlike many cave systems that stay damp and dripping, these caverns are completely dry, which has helped preserve their unique character over the millennia. There is still active archaeology in one section, and researchers believe the airflow makes the 65-mile journey to the Grand Canyon itself — a dye was pumped into the cavity to test the theory, and two weeks later, the colored air appeared out of the side of the Grand Canyon.
Atmosphere & Setting
Colored backlighting in the caverns creates an incredible picturesque “cavescape” that’s perfect for a romantic dinner, and one of the most striking features is the quietness — no loud music, no buzz of air conditioning, no noise, with staff and guests alike speaking in muted tones that only add to the delicate atmosphere of the space.
Arizona summers can be brutal, with surface temperatures soaring well over 100 degrees — but down in the caverns, you’ll find a constant 56 degrees no matter what season you visit, making the Caverns Grotto especially appealing during those scorching summer months when you need a break from the heat but still want to enjoy a nice meal out. The stable temperature comes from the insulating properties of 200 feet of solid rock above your head. Winter visitors appreciate the warmth compared to the chilly desert nights, while summer guests relish the cool relief.
On the surface, the entrance area has its own quirky roadside personality — a giant dinosaur stands next to a rusted-out lawnmower, and an old motorboat sits beside a petrified log. It’s delightfully chaotic in that classic Route 66 roadside-attraction way, setting the tone for the wonderfully strange experience that awaits underground.
Other Considerations
Do I need a reservation? Reservations are required to eat at Caverns Grotto, which exclusively serves four tables at a time. Reservations are highly recommended, especially on weekends. Don’t show up hoping to wing it — this is a one-of-a-kind experience, and spots fill fast.
What does it cost? Accessing the restaurant is a journey in and of itself: guests are lowered 21 stories underground by elevator to reach the restaurant, where for $49.95 per person, they can enjoy a lunch entree and a side. Dinner pricing may vary, so check the official website for the most current details.
Can I bring my kids? Paved walkways with handrails make the cave tours accessible for all ages. The cave tours are a fantastic, educational adventure for curious young minds — just keep in mind the intimate Grotto seats only 16 people total, so it’s best suited for families who can plan ahead and keep mealtime relatively calm in the underground setting.
What about staying overnight? There is a hotel room inside the caverns, 200 feet below ground level, costing around $900 per night for two guests. This unique hotel room books up a year in advance, so plan way ahead if that once-in-a-lifetime experience is on your radar. For a more accessible stay, the inn offers roomy cabins and cozy rooms, and if you prefer to sleep under the stars, an RV park and campground is also available on site.
How do I get there? Grand Canyon Caverns is located in Peach Springs, Arizona, along historic Route 66 — about an hour west of Kingman and an hour east of Seligman. It’s also possible to visit as a day trip from Las Vegas, with a drive of approximately 3–4 hours each way. The scenic Route 66 drive through northern Arizona makes the journey itself part of the adventure.
