Best Time to Visit Devil’s Den

There’s no such thing as a “best time” per se. The Devil’s Den it’s popular year-round and does not have a low season. It gets packed with snorkelers in the summer, and it is very popular for SCUBA divers during the winter. It’s also a great place for couples to snorkel or SCUBA in!

About the Devil’s Den Prehistoric Spring

The Devil’s Den is essentially an underground cave spring that has an opening exposing it and providing 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 Devil’s Den Florida Form?

It took millions of years for Devil’s Den to form. Soft limestone rock, also 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 under heavy pressure, resulting in limestone. The area is all that’s left 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.

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

Entering Devil’s Den Florida

Something is encapsulating and mysterious about this spring. Perhaps it’s the name or the fact that it’s essentially 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 that leads you to the top of the metal stairs that descend onto the platform at the bottom. Entering the concrete steps is eerie. You don’t know what to expect even though you’ve seen the photos, making 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. Even on a hot summer’s day in Florida, it is chilly at first feel. 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 I assumed (you know what assumptions are) that we could snorkel under into spots of the cave. This is not the case; you will float on the surface and swim in a circle if you snorkel. If you dive, you can explore what’s hidden beneath. Four underwater passages extend from the pool under the opening from 5 feet to 90 feet under 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?

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

Devil’s Den Florida Entry Sign

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

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 around floating on the top, you will see diver after diver exploring and many returning up from below with flashlights to guide them to the surface. The divers seem to appear from nowhere, you can be gazing at rock formations, and suddenly you see the light followed by a diver. It is unusual and creepy at the same time. Then there are the snorkelers, be prepared to bump into each other. It’s almost unavoidable.

Perhaps the most captivating view of all is the karst window – the opening above the cave allows the sun to shine through. It is covered in moss, which dangles down, 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 certification. Devil’s Den is connected to a cave system and a spring water source.

Getting SCUBA Certified at Devil’s Den

Devil’s Den offers a unique cavern diving experience for people 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 not wanting to learn in the ocean. Instead of rolling backward into a murky, wavy sea, it’s much easier to slip into crystal-clear, calm water. 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.  Mid-October 199o, 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 they did not have the correct equipment.

Devils Den

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. It was regular mist resulting from a 72-degree spring water temperature and the surrounding cold air. Like how your breath becomes visible on a cold winter day, this effect is nothing special.

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

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

Two Hawk Hammock

Two Hawk Hammock offers comfortable, affordable lodging to travelers. Ideally, the property is within walking distance from Devils Den and Cedar Lakes Woods and Gardens. The Oak Hammock, Coy Pond, and other property features are open daily to guests. 

My recommendation is to stay at the brand-new Quality Inn Suites that was built in 2014 in Dunnellon which is about 24 miles away. If you stay here you can also take in the Rainbow River.

Or, you can stay off-site in a treehouse or cabin!

Frequently Asked Questions:

Can you swim at Devil’s Den?

The technical answer is yes because you have to “swim” to enter. However, you must be snorkeling or diving to enter. You cannot enter without snorkeling or diving equipment. In other words, you cannot join for a leisurely swim.

Why is it called the Devil’s Den Prehistoric Spring?

When the original discoverers came upon Devil’s Den, Prehistoric Spring smoke rose from the karst window, which they assumed to be rising from Hell or Satan’s lair. Once you see it for yourself, you will understand why. They quickly realized it was steam rising from the spring. As a result, the name Devils Den was given, and it’s since then been adapted to Devil’s Den Prehistoric Spring because it dates to 7,500 BC.

FYI: Only on cold winter mornings can you see steam.

Is Devil’s Den dog friendly?

No, the only animals permitted are service animals.

Closing Thoughts

Devil’s Den Prehistoric Spring is an exciting place to visit. Another Atlas Obscura pick – a resource known to travel enthusiasts for highlighting unique things to do worldwide. Particularly of interest to those that dive. I’m glad that we experienced this. The only drawback is that this is not a day attraction. It’s an experience for a couple of hours. You get two hours to snorkel, but this is ample time. As a result, if you are planning to check this out, I suggest you combine it with another activity or have plans for the rest of your day.
