3. Devil’s Den Spring, Florida
Welcome to a different dimension — Devil’s Den Spring, a majestic cave located in Williston, Florida. This stunning cave resulted from a karst window, a cave roof that basically collapsed and revealed the marvelous Devil’s Den Spring. If you’re in love with cenotes, and diving, of course, then this cave should definitely be on your list.
Here divers can see fossil beds and ancient stalactites dating back 33 million years, all through a crystal-clear water with a 54-foot depth and a temperature of 72ºF year-round. This sinkhole is open for tourists seven days a week during all seasons, so if you have a strong feeling about it, maybe it’s time to look for diving gear.
Fun fact: Devil’s Den Spring gained its name on a cold winter morning when some early settlers saw a steam-like smoke rising from the karst window.
