You’ve probably seen the beaches and maybe floated down a lazy river or spent a day at one of those big, splashy water parks.
But there’s a hidden spot in Florida that feels straight out of a fantasy movie, and hardly anyone talks about it.
We’re talking super clear water in a cave, sunlight streaming through, and views so unreal you’ll wonder if you’re still in Florida.
So if you’re up for a swim that’s unlike anything you’ve done before, keep reading because this hidden spring is seriously wild.
Where Is It?
Devil’s Den Prehistoric Spring is tucked away in the tiny town of Williston, right in Levy County.
It’s about 35 minutes from Gainesville, an easy 1.5-hour drive from Orlando, and a little under 2 hours from both Tampa and Jacksonville.
So if you’re road-tripping through the state or already hanging out near those cities, it makes for a perfect day trip.
About
Devil’s Den is a crystal-clear underground spring in a massive prehistoric cave, with hanging vines, ancient rocks, and a ceiling hole that allows sunlight to spill in.
It’s one of the most unique places to snorkel or dive in Florida, with 72-degree water year-round, perfect for exploring even in winter.
The name might sound spooky, but it actually comes from steam that once rose from the cave’s chimney-like opening on cold mornings, resembling smoke from a den.
If you think that’s cool, it gets even better: scientists have found fossils of mastodons, saber-toothed cats, and even prehistoric humans in and around the cave.
As for the spring, it drops about 50 feet deep, with visibility reaching up to 100 feet when conditions are right.
The water is so clear that you can easily see the bottom from the surface, making every activity feel like floating through history.
When you arrive, don’t expect a flashy setup, as Devil’s Den keeps things simple, rustic, and centered on nature.
If you’re looking for something totally different from a Florida beach day, Devil’s Den belongs on your list.
Things To Do
Once you’ve had your first look at the spring’s jaw-dropping beauty, it’s time to get into the water.
Heads up: Devil’s Den is a snorkel and dive site that’s privately owned, and general swimming isn’t allowed.
The good news? Snorkeling is the star here, and the short staircase that leads you straight into the cave makes it feel like you’re entering another world.
Once you’re in the water, you can float over ancient rock ledges, glide through archways, and peek into small underwater nooks where fossils were once found.
You’ll need to reserve your spot in advance (required), and each session typically lasts about 90 minutes with gear rentals available if needed.
Now, if you’re scuba certified, Devil’s Den is a must-visit for an unforgettable experience.
The underwater visibility is incredible, with natural light streaming through the skylight by day, though many divers bring flashlights to see into the dark areas.
With plenty of platforms and training areas, it’s ideal for beginners yet still cool enough to impress experienced folks.
Just remember, you’ll need a dive buddy and proof of certification to enter, since solo exploring isn’t allowed.
Prefer to stay dry? Stay up top and look down through the cave’s opening for a stunning view of the spring below.
You can also relax in the picnic area with tables and grills, so bring lunch and make a day of it.
If you’re planning to stick around a bit longer, you can choose from cozy cabins, tent campsites, or RV spots for an overnight stay.
