Did you know there are 45,000 caves and caverns in the contiguous US alone?⁠ ⁠ This includes the longest cave system on earth—meaning there’s really no limit to the number of underground passageways available for you to explore, from lava tubes to dive sites, replete with stalagmites and stalactites. ⁠ ⁠ From a full-on dive site at Devil’s Den Spring, a prehistoric underground river that looks like a cenote, to Ruby Falls, a 145-foot underground waterfall, we’ve compiled a list of the most beautiful caves you have to visit.⁠ ⁠ Click the link in our bio for more — just please don't watch “The Descent” before you head out… trust us.⁠ ⁠ ✍️: eatsdrinksandleaves⁠ 📸:⁠ 1.
