Exploring Devil's Den Prehistoric Spring
Nestled in the small town of Williston just outside of Ocala, Florida, Devil’s Den Prehistoric Spring offers a truly unique snorkeling experience. This underground spring set within a dry cave maintains a constant 72°F year-round, making it an ideal destination for water enthusiasts during the hot Florida summer months. And its central location makes it easy for a day trip. Read on for all the tips about snorkeling in Devil’s Den!
The name “Devil’s Den” originates from the steam that rises from the spring on cold mornings, creating an eerie, smoky appearance that early settlers associated with the underworld.
Why Snorkeling in Devil's Den is Such a Unique Experience
Devil’s Den combines natural beauty, geological wonder, and prehistoric history—all within a submerged cave. Unlike ocean or river snorkeling, you’re floating inside a cave that dates back over 10,000 years surrounded by ancient limestone and fossils embedded in the walls. It’s like swimming through a piece of Earth’s history! A circular opening at the top of the cave allows a shaft of sunlight to beam down into the spring. This “natural skylight” illuminates the crystal-clear water and creates an ethereal, almost magical glow.
Like most Florida springs, the water is remarkably clear, offering visibility up to 75 feet. Even from the surface snorkelers can see rock formations, fossil beds, and fish swimming below. Snorkeling in Devil’s Den feels like an Indiana Jones-style adventure—but without the chaos. Once you’re in the water, it’s quiet, peaceful, and surprisingly calming, even though you are in an underground cave!
There are few, if any, snorkeling spots in the entire country that allow you to explore a subterranean spring inside a dry cave. Devil’s Den is truly one of Florida’s most unusual natural wonders.
Getting There
Devil’s Den Prehistoric Spring is centrally located in the state near the Ocala National Forest, and is just under two hours from Orlando and from Jacksonville. Both drives are mostly scenic and straightforward, making Devil’s Den a great option for a day trip or weekend getaway from central or northeastern Florida.

A Glimpse into History
Devil’s Den is not just a natural wonder but also a site of historical significance. Fossils of extinct animals, including mastodons and saber-toothed cats, have been discovered here, dating back to the Pleistocene Age. You’re swimming and snorkeling in the footsteps (or paw prints) of ancient prehistoric creatures from the ice age!
Some of the fossils and findings from Devil’s Den are displayed at the Florida Museum of Natural History in Gainesville.
What to Expect When Snorkeling in Devil's Den
Upon arrival, you’ll be greeted by the sight of a sinkhole leading into the cave. Inside, the clear blue waters and ancient rock formations create a mesmerizing environment. Snorkelers can explore the cavern for up to 90 minutes per session, with timed entries in order to avoid overcrowding.
Snorkeling in Devil’s Den isn’t your typical open-water swim—it’s a surreal adventure through a prehistoric cavern filled with crystal-clear spring water and dramatic rock formations. The spring sits 54 feet below ground level inside a cave, which means you’ll be entering through a staircase leading down into a cathedral-like chamber with the only sunlight filtering in through the natural opening in the ceiling. It’s a setting that feels like entering a secret grotto.
What You'll See Above the Water
As you descend down the rocky steps into the spring, be sure to hold the hand rails. The steps can be wet and you have to allow your eyes time to adjust to the low light. The inside of the cave is awe-inspiring, with high limestone walls, stalactites, and a wide open cavern that echoes slightly with every splash.
You’ll float on the surface during snorkeling, but even from there you can see down to the bottom of the spring thanks to the incredible water clarity. Light bouncing off the cave walls and water gives everything an otherworldly glow—perfect for those picturesque views and photo-worthy moments.
...and What You'll See Under the Water
If you’re snorkeling, you’ll be able to gaze into the depths and explore the upper chamber of the spring. Visibility can be 75 feet or more on a good day, and you’ll see ancient rock formations that have been shaped by thousands of years of water flow, fossil beds embedded in the limestone, and colorful fish species swimming through the spring.
For scuba divers the experience goes even deeper—literally. Certified divers can explore the full extent of the spring down to a maximum depth of about 54 feet. There are four underwater passageways (though they’re not cave-diving rated), and several platforms for dive training.
You’ll want to bring your dive certification card to go below the surface, and Devil’s Den has air tanks, wetsuits, and gear rentals available if you don’t have your own.
Planning Your Visit to Devil's Den
To ensure a smooth experience when snorkeling in Devil’s Den, here are some things you need to know:

Fins, snorkel and masks are required when entering the spring.
Guests that don’t wish to snorkel or go in the spring can stay above-ground and enjoy the grounds, but they still have to have a guest pass that is a reduced price.
