The 23 Most Magical Caves in the United States

1 | Antelope Canyon; Page, Arizona

Where to fly: Phoenix Sky Harbor International Airport (PHX)

This slot canyon in Arizona is one of the most awe-inspiring caves in the world. It's split into two sections—the "Upper Antelope Canyon" (otherwise known as "The Crack") and the "Lower Antelope Canyon" (or "The Corkscrew"). This ancient canyon was formed by the erosion of Navajo Sandstone, mostly due to flash flooding. The best time to see Antelope Canyon is during the summer, when the natural light hits its walls at just the right angle to create a warm red glow. This national treasure is only accessible via guided tours, which can be photography-based, hiking-intensive, or more in-depth, depending on the time of year and flooding potential.

Pro tip: After your trek through the canyon, remain immersed in the impressive scenery by booking a room at the Lake Powell Resort, where you can take a boat tour, dinner cruise, or rent a powerboat to explore the perimeters of the resort.

2 | Carlsbad Caverns; Eddy County, New Mexico

Where to fly: El Paso International Airport (ELP)

These caverns, which are located in the Guadalupe Mountains of New Mexico, once served as a coastline for an inland sea.

After a trip through the cavern, visitors can revel in the wonders of the Zen Garden, an area full of marble monoliths that were uncovered during the hydraulic mining of the Gold Rush era.

Actually, archaeologists have found numerous remains in Moaning Cavern, which in turn led to theories about it being haunted. So, if you can set aside your fear of ghosts, walk, climb, or rappel your way through Moaning Cavern for one of the most breathtaking experiences of your life.

Situated on Pigeon Mountain in the Appalachian Plateau of rural Georgia, Ellison's is a top destination for expert cavers and spelunkers from around the world, ready to test their skills on one of the many vertical drops that exist in the cave. It features the two deepest pits in the continental United States—"Fantastic" (586 feet) and "Incredible" (440 feet)—along with five other vertical drops down to the bottom. However, despite the adventure teeming from every surface of Ellison's Cave, the Georgia Department of Natural Resources warns that only those with an extensive knowledge and practice of single rope technique climbing should try to master this descent; conditions can often prove to be dangerous for those with less experience.
