The Devils Den Spring – The Ultimate Prehistoric Adventure for Snorkeling and Diving

The Devils Den Spring – a Prehistoric Spring is something most Floridians know about. A couple of years ago, a spree of promotional videos captivated the imagination of anyone who did not know about this spring. If you’ve seen any of those videos or pictures like me, you probably wonder what it’s like to visit. Most specifically, you probably want to know what the experience is like. Devil’s Den Prehistoric Spring is a privately owned scuba diving training center, where you can also snorkel to experience.

Devils Den Spring Location

It is located north of Ocala and south of Gainesville, in Williston, a small town. The Devil’s Den Prehistoric Spring is in the middle of rural Florida. And while this might be off the beaten track for most, if you are interested in caves or diving, this is an area to check out. This area is also home to the Blue Grotto Dive Resort, another cave system you can explore.

Getting to The Devil’s Den in Florida

Devils Den Prehistoric Spring is at 5390 NE 180 Ave, Williston, FL 32696. Add the address to your GPS, and off you go.

You set the address long before you enter rural areas because plenty of places here have no Wi-Fi.

Best Time to Visit Devil’s Den Spring

There’s no such thing as a “best time” per se. Den Devils Den is popular year-round and has no low season. It gets packed with snorkelers in the summer and is very popular for SCUBA divers in winter. It’s also an excellent place for couples to snorkel or scuba!

About the Devil Den Prehistoric Spring

The Devils Den is essentially an underground cave spring with an opening that exposes it and provides light. This is formed by a karst window created from the dissolution of soluble rocks.

The original opening at the surface appeared to be a sinkhole. Before 1990, visitors had to squeeze through a small hole to reach the spring waters. Once the cave became open to the public in the mid-1990s, the opening was enlarged to create a more accessible access point. Predominantly a dive center, the company that owns it offers scuba diving and snorkeling experiences.

How Did The Devils Den Florida Form?

It took millions of years for Devil’s Den to form. Soft limestone rock, known as karst, was dissolved by slightly acidic groundwater. Karst limestone is a soft rock containing ancient shells, plants, and animal remains. The organic material, such as shells, skeletons, and feces, was compressed underhighy pressure,formingn limestone. The area is all that remains from millions of years ago, when Florida was a giant coral reef submerged under warm, shallow waters. Karst limestone is stunning, with holes poking through it, sometimes filled with water. There are pinhole-sized holes and huge caverns. Also, in Florida, there are substantial cave networks beneath the ground.

Reservations & Getting In

Devils Den is open for business, but they enforce social distancing. Once upon a time, it was the first to come first in. Diving and snorkeling are now only available by reservation. ​Each participant must register individually. Guests must abide by the 6-foot social distancing guideline.

Devils Den Hours of Operation

Devil’s Den is open year-round, 364 days a year. It is not available on Christmas Day.

• Monday – Thursday: 9 am to 5 pm
• Friday, Saturday, and Sunday: 8 am to 5 pm

The last water entry is at 4 pm, 1 hour before closing time, and the main gate closes at 5 pm.

Entering Devils Den Spring

Something about this spring is encapsulating and mysterious. Perhaps it’s the name or the fact that it’s an underwater cave. Either way, even if it does not have an enticing title, you know it will be an experience once you see the entrance. Unlike others, if you’re into Instagram, always searching for an epic shot or a photographer, this place was made for you!

You enter via a concrete staircase leading to the top of the metal stairs, which descend to the platform at the bottom. Entering the concrete steps is eerie. Even though you’ve seen the photos, you still don’t know what to expect, which makes your heart race. Then, when you visit the spring, it’s as if you’ve personally discovered an oasis—reminded that you did not by the group of people gathered on the entrance platform.

Down the metal stairs to the entrance platform, and immediately, you are awoken by the temperature of the water. The underground river is a constant 72 degrees. It is chilly to the touch, even on a hot summer’s day in Florida. We opted to snorkel because we are not certified divers. And, even if we were not sure, I would dive here simply because I am a tad claustrophobic, and the depths here would be too much for me. Add to this, you can only see so far before you need a flashlight. This freaked me out.

Depth of the Devil’s Den Florida

The cave reaches depths of 54 feet, and the surface is 120 feet wide. I must admit that it’s smaller than I anticipated. Or maybe a better way to describe this is that I assumed (you know what assumptions are) we could snorkel into spots in the cave. This is not the case; if you snorkel, you will float on the surface and swim in circles. If you dive, you can explore what’s hidden beneath. Four underwater passages extend from the pool, ranging from 5 feet to 90 feet below the water’s surface. The passages contained animal and human remains dating back to approximately 7,500 BC. Don’t worry; you will not run into remains; they were removed.

How Large Is The Devil’s Den Spring?

The surface diameter is 120 ft. It is the shape of an upside-down mushroom.

Devils Den Florida Entry Sign

As you enter the Devil’s Den in Florida, you will be met with an entrance sign outlining the rules of engagement. Naturally, your participation requires you to follow these rules.

Devils Den, Florida Warning Sign

The infamous warning sign underneath the water warns all who venture off the risks ahead. Notice the Grim Reaper. There’s a reason for this. People have died in this spring.

Snorkeling Devil’s Den In Florida

Once you float or jump off the entrance platform, you begin to experience what everyone is here for—the underwater view of the cave system. The water is clear, but only for a few feet. You will see the fish that live here, and if you are lucky, you’ll see one of the resident turtles. As you swim aroun,d floating on the top, you will see diver after diver exploring, many returning up from below with flashlights guiding them to the surface. The divers appear from nowhere; you can gaze at rock formations, and suddenly, you see the lig,ht followed by a diver. It is both unusual and creepy. Then there are the snorkelers; be prepared to bump into each other. It’s almost unavoidable.

Perhaps the most captivating view is the karst window – the opening above the cave allows the sun to shine through. It is covered in moss that dangles, giving the cave an overgrown, menacing look, but it’s fitting. We spent about an hour taking in the beauty of both before we decided to ascend.

SCUBA Diving Devil’s Den In Florida

You only need an open-water certification to dive inside Devil’s. Technically, Devil’s Den is not a cave dive. Unlike caves, the surface is always accessible and open.

Due to the lack of overhead obstructions, it does not require cave-diving training or certificatioDenDevil’s Den is connected to a cave and spring water sources.

Getting SCUBA Certified at Devil’s Den

Devil’s Den offers a unique cavern-diving experience for those seeking SCUBA certification. Anyone nervous about diving in the ocean for the first time would benefit from the controlled, crystal-clear conditions.

This would be an excellent choice for people who do not want to learn in the ocean. Instead of rolling backward into a murky, wavy sea, slipping into crystal-clear, calm water is much easier. There’s no danger from sharks or alligators there, either.

All dive instructors who offer lessons out of Devil’s Den are independent providers.

Note: Devil’s Den doesn’t offer Nitrox, but you can fill your tanks with Nitrox at another nearby dive site, Blue Grotto, which is less than 2 miles away.

Deaths in Devil’s Den Spring, Florida

There have been at least two documented deaths at Devil’s Den Spring.

First Incident – 1990

This was a fairly open-and-shut case.  In mid-October 1990, a solo open-water diver became lost. The body recovery was performed by Rescue/Recovery Team Members Kelly Brady, Steve Berman, Ed Paradisio, Mark Leonard, and Lamar Hires and required side mounts.

Second Incident – 1995

Another incident in 1995 led to the tragic death of a scuba diver. The diver and his dive buddy were firefighters visiting from out of state. One of the two died after they decided to pull down the fence that blocks off Devil’s Den’s cave section.  The firefighters had no cave or cavern training and no proper equipment.

Why Call It “Devil’s Den”?

Early settlers discovered Devil’s Den on a cold winter day in the early 1800s, giving it its name. It seemed as if steam was rising from a hole in the ground.

The exact opposite is true. What they saw was not even steam. Regular mist resulted from a 72-degree spring water temperature and the surrounding cold air. This effect is nothing special, like how your breath becomes visible on a cold winter day.

People call Devil’s Den Spring many names, like Devil’s:

• Den Prehistoric Spring
• Cave
• Den Cave
• Cavern
• Den Cavern
• Spring
• Den Spring

John’s Oasis at Devil’s Den

John’s Oasis at Devil’s Den is the newer family-friendly water area located on the grounds of Devil’s Den Prehistoric Spring in Williston, Florida. While Devil’s Den itself is the famous underground prehistoric spring inside a cave, John’s Oasis was added as an above-ground lagoon-style swimming and recreation area so visitors who are not diving or snorkeling in the cavern still have a place to enjoy the water. It’s designed more for casual swimming, relaxing, and family fun, making Devil’s Den a destination where divers, snorkelers, and non-divers can all spend the day together.

Entry Cost Of John’s Oasis

John’s Oasis is included with snorkeling admission to Devil’s Den, which currently costs $30 per person for a 90-minute snorkeling session in the underground spring, and that price includes access to the oasis for the day. If someone only wants to visit the property without entering the spring, there is a walk-through/day pass for $15 per person. Snorkel gear rental is extra; a full mask/snorkel/fins package costs $15. Reservations are required for snorkeling, with a $5 non-refundable deposit due when booking and the remainder paid on arrival.

How To Spend Your Time At John’s Oasis

The biggest draw of John’s Oasis is that it gives guests a warmer, easier swimming area than the underground spring cavern. The underground spring stays at a constant 72°F year-round, which can feel chilly, and is open only to snorkelers and certified divers. John’s Oasis offers a relaxed environment where people can swim, float, and lounge without the equipment rules or time limits of the main spring. It’s especially useful for families with children, or for groups where some people want to dive Devil’s Den while others want to relax in the water.

The atmosphere at John’s Oasis is very different from the dramatic cavern experience of Devil’Denen. The den itself is dark, enclosed, and surreal, with sunlight shining through the cave opening and ancient rock walls all around—an unforgettable snorkeling or diving experience. John’s Oasis, on the other hand, is open-air, bright, and laid back. It feels more like a natural swimming lagoon, giving the property a resort-like balance between adventure and relaxation. Many visitors use the oasis to unwind after their snorkeling session in the cave.

Another Atlas Obscura pick – a resource known to travel enthusiasts for highlighting unique things to do worldwide, particularly of interest to those who dive. I’m glad that we experienced this.
