Many people travel to Florida to make their way to the theme parks and beautiful beaches, and they’re certainly worth a visit. However, if you’re starting to feel like you’ve “been there, done that” and want to find a few new experiences in Florida, we’ve got just the place for you! Today, we’ll look at Devil’s Den in Florida and share why we think you should add it to your travel itinerary while in the Sunshine State.
What Is Devil’s Den in Florida?
Devil’s Den in Florida is an underground river. It formed when the roof over an underground river collapsed. It’s a privately owned body of water near Williston, Florida that acts as a scuba diving training facility and other recreational activities.
The cave reaches a depth of 54 feet and has a surface diameter of 120 feet. Four underwater passages extend from the opening and dip between 5 ft and 90 ft under the water’s surface. One of the passages that’s 70 ft underwater had animal and human remains dating back to 7500 BC.
Why Do They Call It Devil’s Den?
The water in this cave remains 72 degrees year-round. Cooler temperatures in Florida cause a visible foggy plume to emerge from the cave entrance. The early settlers in the area thought it resembled a chimney from Hell. This smoky output occurred often enough that it became known as the “Devil’s Den.”
5 Reasons You Should Explore Devil’s Den in Florida
With so many great places to visit in Florida, you may be wondering why this is worth your time. Let’s explore a few reasons we think it deserves to make its way into your travel plans.

1. Scuba Dive Four Ancient Underwater Passages
There are four ancient underwater passages. It’s a unique experience that could also lead to some pretty cool discoveries. Divers have found many artifacts within these passages dating back to 7500 BC. Along with human remains, divers found remnants of extinct species such as mastodons and ground sloths.
2. You Can Snorkel in the Gorgeous Natural Den Pool
If scuba diving is too intense for you but you still enjoy exploring, snorkeling in the natural den pool might be the perfect fit. You could look through the crystal clear water without needing to dive in fully. You’ll still get to experience what the ancient passageways have to offer, just from afar.
Keep your eyes open, and you’ll likely spot a fish or two. If you’re lucky, you may even spot the resident turtle.

3. You Can Check out Prehistoric Fossils
If finding prehistoric fossils sounds like a fun afternoon, you’ll be in for a treat. Scuba divers can scour the floor of this natural pool for prehistoric fossils. Some divers have even found the remains of a saber-toothed cat! You never know what you might discover.

4. There Are a Lot of Geologic Features
Fossils and artifacts aren’t the only good finds in this sinkhole. You’ll enjoy the sights of an underwater river full of interesting geologic features. The natural karst spring will leave you in awe. The quiet cave where you can hear dripping water can leave you feeling like you’ve become an explorer yourself.
While in the cave, you’ll experience acidic groundwater from eroding limestone and an ever-changing water level. Because an underground system of waterways feeds the water body, the water level changes naturally. Events such as heavy rains elsewhere can cause the water to rise as much as 8-10 feet.

5. Camping and Cabins Available Onsite
If you want to immerse yourself in the experience, you could enjoy the onsite camping and cabin options. There are RV camping sites available with full hookups, tent sites, or you could stay in the provided cabins. At any rate, you’ll be comfortable and in convenient proximity to the Devil’s Den. Most RV sites offer full hookups.
Admission fees to Devil’s Den are separate from camping and cabin rental fees. So plan accordingly if you want to stay and visit the den.
