Cave Diving 101
Underwater cave diving is a risky endeavor, no matter how much experience you might have. Even the most seasoned deep-sea divers often fall victim to the perils of cave exploration. For example, the South African diving prodigy, Deo Dreyer, tragically lost his life in 1994 while exploring Bushman’s Hole.
Clearly, tragedy can strike anyone who makes the decision to embark on a cave diving adventure. While most cave dives are safe for divers, it must be emphasized that cave diving is a sport that is full of risks and safety hazards. In short, it is not for the faint of heart.
Top Cave Diving Risks
“Is diving dangerous?” This is one of the most commonly asked questions we receive on a near-daily basis. In short: yes, cave diving is an extremely dangerous pastime that must only be attempted with extensive training and diving experience under one’s belt.
The top risks assumed when cave diving include running out of oxygen, physical exhaustion, violent encounter with aquatic life, becoming lost, and decompression sickness. It is no secret that cave diving is a potentially dangerous endeavor that should never be taken lightly.
A History of Cave Diving
Modern cave diving began in the 1940s with the invention of scuba equipment. Before the invention of scuba gear, cave divers used lanterns, snorkels, and umbilical hoses to explore underwater caves in a more limited fashion. However, it was not until the introduction of the “Aqua-Lung” in the 1940s that the modern sport of cave diving took off.
Cave diving first became popular as a sport in Florida and the United Kingdom, where access to beautiful caves and grottos are commonplace. In 1936, the first internationally sanctioned underwater cave dive took place in the United Kingdom. For decades, the UK remained the diving capital of the world until the 1970s when its popularity boomed in the United States.
In recent years, the rise of sports caves and resort caves in the Caribbean and West Indies have caused cave diving to become a luxury hobby. Many wealthy divers from around the world tour exotic locations to find untapped caves and to find greater underwater challenges. Today, dozens of countries around the world have official cave diving organizations.
Eagle’s Nest Cave
Eagle’s Nest Cave ranks highly on our list of the top cave diving locations in the world. This is because Eagle’s Nest Cave is one of the deepest dives in the central Florida cave network.
Eagle’s Nest is also home to at least ten deceased divers since the early 1980s. Obviously, Eagle’s Nest is nowhere near an entry-level dive. In fact, it should only be attempted with the aid of a guide, a support team, and loads of heavy-duty training. When diving Eagle’s Nest, never take any unnecessary risks or chances. After all, your life is at stake.

Cenote Angelita, which translate to “Little Angel” is a Mexican cavern formed by a massive rock collapse. It is nearly 200 feet deep and filled with lush vegetation. Since it is not as deep as other nearby caves, it is an excellent choice for intermediate divers who are looking to make next step in their diving careers.
This Mexican cave is a true natural beauty. It is a halocline, which means that it is filled with both fresh and saltwater as there are several shifts in the salinity of the water throughout the cave. In fact, the deeper you dive the most concentrated the salt water becomes. Near the surface, however, the water is fresh and clearer. This makes for some interesting optical illusions.
Kilsby’s Sinkhole is one of Australia’s prized diving caves. There are few caves in the world that are so structurally unique as Kilsby’s. The cave is in the most unassuming of places—the middle of a sheep farm. In fact, if you are not looking out for it you are likely to miss it altogether.
To access Kilsby’s Sinkhole, you need to descend a series of stairs until you hit the blue lagoon. Once there, you are free to dive as you please and explore its many underwater wonders. The water is crystal clear and surprising well lit, which makes it a great choice for entry-level cave divers. To discover more about Kilsby’s, visit their website here.
Orda Cave is an underwater diving cave located in the Russian Ural Mountains. The cave flows through an outcropping in the mountains and stretches for over three miles underground. It is one of the longest underwater caves on the planet, and it is the biggest gypsum cave in the world.
Since Orda Cave is loaded with scenic hotspots and well-lit environments, it is an excellent location for divers looking to photograph their adventure.

We recommend Orda Cave for anyone in search of a beautiful cave diving expedition that is not too challenging.
Indian Springs is one of the crown jewels of North Florida’s cave system. Indian Springs is a spring pool that is 30 feet deep and nearly 200 feet in diameter. As such, it is a great low-risk adventure for those who are looking to just get their feet wet when it comes to cave diving. However, its gorgeous scenery makes it a prime destination for even veteran divers.
The spring is located near the headwaters of the Wakulla River and features many amenities. For example, the location has family-friendly attractions such as water slides, campgrounds, and observation decks.

The Great Blue Hole is a diving experience unlike any other. It is dark, remote, and uniquely challenging. It is not meant for inexperienced cave divers, as it is often considered one of the most difficult and dangerous diving caves the world has to offer. In fact, at lower depths, the Great Blue Hole is notorious for inducing nitrogen narcosis, which is a serious hazard for divers.
