What could be more fun than an entire day spent exploring one of the coolest caves in Arizona? Grand Canyon Caverns is a 65-million-year-old cave that not only allows visitors to descend 200 feet into its deepest depths, but also has a restaurant where you can dine underground. We believe that’s an adventure unlike any other. A day trip to Peach Springs to see these hidden caves is fun for the whole family. We love this cave-themed day trip in Arizona so much, and we bet you will love it too. Check it out!

Next time you find yourself on Historic Route 66 near the town of Peach Springs, keep an eye out for the friendly dinosaur statue on the side of the road.

When you see it, you'll know you have arrived at Grand Canyon Caverns: the largest dry caverns in the U.S.

This hidden, little-known subterranean oasis was formed over 65 million years ago, and visitors can descend 200 feet below the earth's surface to explore its deepest depths.

There are several tours available, each one offering a totally unique experience.

Choose between the classic tour, which showcases all of the cave's major highlights, two adventure tours that lead you into hidden areas most people don't get to see, and even a ghost tour on which all the lights are turned off!

During your time in the caverns, you can also enjoy one of the most unique dining experiences in Arizona: the Caverns Grotto.

One of our state's only underground restaurants, the Caverns Grotto lets you enjoy a meal surrounded by ancient rock formations.

The restaurant is an ideal setting for both romantic date nights and unconventional family outings.

You might even get treated to some live music while you eat, as the dining area overlooks the caverns' very own underground amphitheater!

On the Cavern Grotto Restaurant menu, you'll find American classics like burgers and salads, and everything is delicious as can be.

Some people even say these are the best burgers on Route 66, but you'll have to try one for yourself to find out.

If, after your meal, you still aren't ready for the fun to end, there's even an underground motel room that sleeps up to six guests.

With a full bathroom, kitchenette, books, and a TV with a DVD player, this one-of-a-kind overnight stay is nothing short of unforgettable.
