Cave Diving - Everything You Need to Know

Cave diving is an experience like no other. The underwater life that inhabits these mysterious formations is, without a doubt, unique and impressive. In addition, it is an activity that motivates teamwork and helps us to balance emotions such as fear, panic or nerves .

If adrenaline is your thing and you are passionate about discovering new worlds under the sea, this kind of dives will leave you amazed. But first, make sure you clarify all your doubts, check what equipment you need (and what not), what are the requirements for cave diving and get advice from experts so you can enjoy with confidence. 

In our post we will guide you on what exactly is cave diving, why you should say YES to an adventure like this and we tell you what you should always take into consideration before embarking on your adventure under the sea. Stick around and find out all about it. 

What does Cave Diving consist of?

Cave diving is an extremely tempting proposal for any adventurous diver. With this modality we can learn to explore underwater caves in a safe and responsible way. 

It can be distinguished because in this type of immersions we reach beyond the area where we have natural light and we do not have easy access to the surface. Taking this into account, it is more than evident that this discipline requires a gradual learning, as well as it implies knowing the essential elements and the techniques that we must apply in this type of scenarios.  

Therefore, this is not an activity suitable for those who are just starting out in the world of diving, but for those with a certain level of training who are looking for new experiences. 

Cave Diving and Cavern Diving Are they the same?

No.❌ Although at first glance they may appear to be the same activity, the truth is that they differ markedly. 

First of all, in cavern diving divers usually dive to a maximum depth of 60 meters and therefore have a certain level of sunlight that facilitates underwater vision. In addition, the exit in this case must always be visible while we are diving. 

However, when it comes to cave diving, it requires a more advanced level of preparation, since it is a discipline that requires going deeper, exploring under underwater rocks. All this implies a low level of illumination and, therefore, a more limited vision of what is at the bottom.

4 Reasons to Dive in Caves

Beyond being a discipline that allows you to acquire a higher level of experience and preparation in the world of diving, it is also a great opportunity to:

  • Discover an endless number of wonderful animals that you won't find anywhere else in the world. For example, in places like the Cuevas de las Gambas you will see swarms of narwhal shrimps, groupers, garden eels, white fulla, flabellines and even sea slugs that gleam with their intense violet color. 
  • Appreciate absolutely breathtaking underwater landscapes, with rock formations such as stalactites and stalagmites that look like something out of a movie.
  • Learn how to handle emergency situations and disorientation, as well as how to move safely inside the caves. 
  • Know how to manage emotions such as panic and nerves. You will be able to stay calm and rely on problem-solving training. 
  • Reinforce the concept of teamwork, because in the caves your companions could be your lifeline in any situation.

What to Consider Before Cave Diving

Physical condition

For a normal dive it is important to be in good health, but when it comes to cave diving this is essential, as it is a key factor in reducing the risk of decompression sickness

Therefore, if you are planning to explore some underwater caves, we recommend you to do some kind of aerobic exercise regularly , at least 2 or 3 times a week, and to follow a good diet.at least 2 or 3 times a week and follow a good diet.

Previous experience

Cave dives also have a certain level of demand with respect to the experience we may have previously. For example, it will be useful if we have knowledge in nitrox diving or rescue diving, in addition to having done simple dives before. 

In fact, it is sometimes recommended to have done at least 10 to 12 dives in the 6 months prior to our cave adventure.

Likewise, mastering buoyancy techniques, both in confined and open water, is absolutely necessary to perform this activity without problems. It is also important to know how to make a 360-degree turn just by paddling with the fins.

To have the necessary equipment

Cave diving is distinguished by the high level of demand, not only on a physical level, but also in the equipment. The most essential thing is to carry as little equipment as possible, in as little volume as possible and only as much weight as possible

To give you a better idea of how you will organize your equipment when cave diving, we will explain below what you need to take with you and what factors you should consider:

  • Vest and regulator

Try to opt for the simplest and lightest models that will help you avoid tangles. Also try to choose those with specific hooks for elements such as, for example, an extra spotlight. 

  • Suit

There are several types of wetsuits, but for your cave diving adventure it is best to opt for one that is no less than 5 mm thick to ensure optimal thermal protection in the underwater environment. If the area where you will dive has very low temperatures we recommend you to evaluate the use of a dry suit.

  • Light spotlight

Lighting is a must when cave diving, so it is definitely better to play it safe by carrying an extra light with extra batteries. Make sure they do not have cords to prevent dangerous entanglements and that they can be easily placed on the BCD when we need to have our hands free.  

  • Fins

One thing you should not overlook before a dive is the type of fins you will be using, and in this case, go for single-bladed adjustable fins. Fins with movable blades or split blades may cause you to tangle with the guide line. Choose a simple but powerful model, which also integrates practical adjustment elements to prevent accidents. 

  • Knife

This element should be small, easy to transport and should have a built-in cutter. 

  • Reel

It will allow you to mark jumps, the entrance/exit of the cave and other necessary indications during the dive.
