Beaches and theme parks get a lot of attention, but if you ask me, Florida’s springs are the best part of our state.

Did you know that Florida may more freshwater springs than any other place on Earth? We have more than 700 springs in Florida.

Here are some of the best springs in Florida.

Devil’s Den

Devil’s Den is one of the most unique and beautiful springs in Florida.

Unlike many other springs in Florida, Devil’s Den is entirely underground in a giant cavern. It’s only accessible via a dark, narrow entrance and stairway.

Inside, the cave opens up into a large, beautiful space, filled with deep, brilliant blue water. It’s magical. Sunbeams shoot down into the water through a round solution hole in the cave’s ceiling, with green plants climbing down toward the water.

Everything adds up to create a truly surreal and amazing experience — it’s like having a Mexican cenote in Florida.

Devil’s Den is an amazing site, and is definitely worth a visit.

But, I must give a big caveat. This site has some special quirks. If you don’t know what to expect, you may be disappointed.

Devil’s Den Spring has on-site camping.

Blue Springs State Park

Blue Springs is a gorgeous spring located near the St. Johns River. It’s located in Volusia County, about 40 miles northeast of Orlando. It’s also commonly called “Volusia Blue Springs” because there are so many springs with the same name in Florida.

Volusia Blue Springs State Park is incredibly popular, and can become very crowded depending on when you go. Be sure to plan ahead, know what to expect, and visit at a good time.

You must also be aware that the spring access can be restricted due to overcrowding in warm summer months, and is closed during the winter to protect manatees.

Blue Springs State Park has a ton of things to do, especially water activities like snorkeling, kayaking, canoeing, manatee watching and more.

There is also a network of trails and boardwalks which follow the spring run, so be sure to bring good shoes if you want to explore on land.

Because Blue Springs State Park is so close to the Atlantic Ocean and Orlando, you’re just a short drive away from some of the most popular things to do in Florida.

Ichetucknee Springs State Park is most famous and popular for tubing down the Ichetucknee River.

Ichetucknee Springs State Park is incredibly busy in the summer, between Memorial Day and Labor Day weekends. During spring, fall and winter, the park remains much quieter and receives much less visitor traffic.

There are many rules for visiting Ichetucknee Springs, and there are seasonal restrictions. While trip planning, be sure to do research before going so you know what to expect.

Ichetucknee Springs State Park does not have on-site camping, but there are several options for camping nearby, including the Ichetucknee Springs Campground.

Gilchrist Blue Springs

Gilchrist Blue Springs is located in north central Florida, inside Ruth B. Kirby Gilchrist Blue Spring State Park. It’s about 45 minutes away from Gainesville.

Gilchrist Blue Spring was privately owned since it opened in 1958, but it was acquired by the state of Florida in 2017 and turned into a state park. It’s the newest state park in Florida, and is undergoing improvements.

Gilchrist Blue Springs is most famous for its beautiful blue water and large swimming area. The water depth is deep over the spring vent, and shallow in other areas. There is a zero-depth beach entry where kids like to play.

There used to be a wooden jumping platform, but it was removed when it was taken over by Florida State Parks because it was becoming unsafe.

Gilchrist Blue Springs is excellent for camping, kayaking, snorkeling and swimming. There are also hiking trails in the state park, and an elevated wooden boardwalk to protect the fragile spring and floodplain ecosystem.

In times of heavy rain Gilchrist Blue Spring may be closed due to flooding along the Santa Fe River.

Admission is often restricted after the park and spring reach maximum capacity.

The park has on-site camping and 23 campsites.

Ginnie Springs

Ginnie Springs is one of the most beautiful springs in Florida, and one of the most over-used.

Ginnie Springs is located in Gilchrist County, about 45 minutes west of Gainesville, near the town of High Springs.

Ginnie Springs features a series of 7 springs which all flow into the Santa Fe River.

Ginnie Springs is popular for many activities, including camping, tubing, swimming, snorkeling, kayaking, paddle boarding, SCUBA diving, and more.

Ginnie Springs is privately owned, and its private management is often controversial. Alcohol consumption is allowed in Ginnie Springs, and many visitors complain that this ruins the spring.

Many visitors complain about trash, obnoxious drunken behavior, loud music, fights, and more. Many avoid visiting on weekends or holidays, when the drunken behavior may be worse. Many visitors also complain that public areas –especially bathrooms– often become disgusting.

The private ownership has also been criticized for selling spring and aquifer water pumping rights to Nestle, which uses the water to manufacture plastic water bottles.

Critics of Ginnie Springs owners are unhappy that water pumping damages the fragile Florida Aquifer, which feeds all springs in Florida. The Florida Aquifer is already threatened by over-pumping, environmental pollution and other threats.

There is on-site camping at Ginnie Springs.

Warm Mineral Springs

Warm Mineral Springs is unlike most other springs in Florida. It’s a geothermal hot spring, and stays warm year-round.

It also has a very high concentration of natural minerals, which makes it a global destination for health and wellness seekers.

Many visitors, especially Europeans, believe that the water has healing properties, and can help with a wide range of health problems.

Warm Mineral is a fascinating place. It’s incredibly deep, has a fascinating history, and a cult following. It is not for everyone, though. Some people love it, and some people hate it.

If you’re near in southwest Florida, anywhere near Tampa or Sarasota, I highly recommend a visit.

Why Florida Springs Exist

Florida’s springs exist because of Karst limestone, which is a type of topography. It’s formed when certain types of sedimentary rocks are dissolved by acidic water.

The most common types of sedimentary rock that form Karst topography are limestone, gypsum and dolomite. Between 10 and 30% of the world rests on karst topography. It forms the earth’s bedrock in many areas.

Karst Geology

Before talking about Florida springs, and the karst limestone that makes them possible, it’s helpful to know a bit about basic geology.

Types of Rock

There are three main types of rocks:

While talking about Karst, we’ll focus on sedimentary rocks.

Sedimentary rock is made from materials like sand, pebbles, shells, and fossils, which come together to form a rock. Some, or all of this material, can be left-over organic material from plants and animals, like coral.

These materials accumulate over very long periods of time. They stack on top of each other to form layers. Over time the layers grow, and eventually become very heavy. The heavy layers are pressed downward on each other, and eventually they harden into rock.

Nature’s Magic Trick: Disappearing Rock

Karst topography is sort of a natural magic trick: water dissolves solid rock. It requires a special set of conditions, and can leave behind amazing natural formations.

Some of the most beautiful, exotic landscapes on Earth have been formed by Karst geology.

This natural magic trick requires a few special ingredients.

  • Lots of rain water
  • Lots of vegetation, which decomposes to create carbonic acid
  • Soluble (dissolvable) sedimentary rock, like limestone, gypsum or dolomite

When Rainwater Becomes Groundwater

Rain falls from the sky. Everyone knows that. But, what happens to rain after it hits the ground? It becomes groundwater.

Lots of things can happen to groundwater:

  • Pool into puddles
  • Flow into creeks and rivers
  • Run into storm drains
  • Soak into the ground

Karst topography has lots of cracks.

The vertical cracks are called joints, and the horizontal ones are called bedding planes. Both types of cracks allow water to collect, and flow through the rock. Sometimes these cracks grow into giant caves, which can be as big as a house. They can also form into fast-moving underground rivers which run for many miles under ground. Sometimes, the groundwater can enter a crack and stay trapped there for thousands of years.

Weathering

Karst topography is soluble, which means that it can be dissolved.

The main process that causes karst topography is carbonic weathering. Carbonic weathering is the result of mixing water with carbon dioxide to make carbonic acid, which then dissolves soluble rock. This type of weathering is an important factor in the formation of subterranean caves.

When atmospheric carbon dioxide is dissolved in water it creates carbonic acid. The carbonic acid percolates through joints and bedding plains. It reacts with minerals within the limestone and creates chemicals, which weather the limestone. High amounts of carbon dioxide makes stronger carbonic acid. Stronger carbonic acid is more effective at weathering and dissolving karst rock formations.

One factor that contributes to the strength of carbonic acid is the amount of organic material in soil. Fertile, lush tropical environments (Like Florida!) provide a lot of plant and animal matter, which are all high in carbon. When rain flows through porous, carbon-rich soil, it creates higher concentrations of carbonic acid.

It’s no coincidence that some of most dramatic landscapes are in tropical SE Asia. In these areas, warm temperatures and lush vegetation create higher levels of carbon dioxide. The tropical climate provide ample rain water, which washes through the soil and creates large amounts of carbonic acid.

All of this carbonic acid eats away at the limestone and other soluble rocks, creating amazing Karst formations.

Underground Rivers

After finding its way underground, water can collect in cracks, and eventually turn into underground rivers. These are called subterranean rivers.

These rivers can take on all sorts of shapes, sizes and characteristics. The water can sit in one place and not move for 100 years, or it can travel several miles in only a few days; it all depends on the underground characteristics.

These subterranean rivers can create their own forces which act on the environment. Besides the the chemical effects of carbonic acid which dissolves rocks, fast-moving rivers erode rock.

Karst Environments around the world

Some of the most amazing, beautiful and sensitive landscapes on Earth are formed by Karst.

In Earth’s geologic past, when the Earth was warmer and sea levels were higher, Mexico’s Yucatan Peninsula was covered by ocean water.

This left the region with a karst landscape made of limestone. This, combined with Mexico’s heavy rainfall and lush tropical vegetation, creates an ideal environment for carbonic weathering and karst geology.

Thanks to this combination of factors, Mexico is home to an amazing series of sinkholes called Cenotes.

How does it work?

We tend to think of rocks as solid, hard objects which cannot be easily broken. You know, like the common phrase, “hard as a rock”, or “tough as a rock”.

Because of the way they’re made, some rocks have a weak-spot: water. Even if they feel strong and hard on the outside, they can be eaten away by water. In fact, one of the most beautiful places on Earth, the Grand Canyon, was formed by flowing water over millions of years. Even the biggest, strongest and hardest rock can be worn away by water.

In Karst topography the water not only erodes rock, but it can actually eat away, too. This only happens in certain types of rocks, but when it happens, the results can be amazing.

How can a rock hold water?

We usually think of rock as a solid piece of material. Sometimes that’s true, but it doesn’t always have to be. There are many types of rocks, and some have very different characteristics than what we’d usually expect.

What do you call a rock that doesn’t sink like a rock?

Pumice is one type of rock that doesn’t behave the way we’d expect it to. In fact, it can actually float in water.

Pumice is a volcanic rock. It’s formed by lava that cools very quickly, leaving lots of air bubbles behind. Some of the air bubbles are visible on the outside of the rock, but some of the bubbles are trapped inside. These little air pockets provide enough flotation that pumice rock floats on top of water.

The Florida Aquifer

The Florida Aquifer is a vast sheet of carbonic rock beneath the soil of Florida. Like the floating Pumice rock, this carbonic rock is not a solid piece of rock like we usually imagine. It varies by location, but much of this underground sheet of rock is filled with little cracks and gaps.

These can be as small as the head of a pin, or as big as a house. Many times, these spaces are filled with water that seeps down from the Earth’s surface.

What is hydrogeology?

Hydrogeology is a sub-field of geology which specializes in the study of groundwater. Many scientists in this field study subterranean water, or underground water.

Although water is a renewable resource, it is not infinite. It is highly vulnerable to over-use, contamination and many dangerous forms of abuse. That’s why groups like the Hydrogeology Consortium, and other scientists, are so passionate about protecting water, which is our most precious resource.

Water: Essential for Life on Earth

Many people around the world rely on underground aquifers for drinking water and survival.

It’s crucial for scientists, communities and individuals to understand the field of hydrogeology.

With a better understanding of science we can be better stewards of our environment and the natural resources we need to survive.

The Role of Hydrogeologists in Society

Hydrogeologists serve their communities in several important ways:

  • Safeguard drinking water supplies
  • Analyze possible sources of pollution
  • Protect natural resources like springs, rivers, wetlands, aquifers and more
  • Analyze the sustainable environmental carrying capacity
  • Determine sustainable withdrawal rates
  • Find new paths of sustainable practices
  • Design and implement new technology
  • Research efficient irrigation practices
  • Analyze the quality of water for safe use
  • Help meet the needs of various stakeholders

Our Hydrogeology Consortium is especially concerned with preserving sensitive Karst environments and our own natural treasures, Florida Springs.
