Diving in Krabi: places, tips, schools, certificate, photos


Here are some tips about snorkeling in Krabi that you should learn before visiting the magical underwater world of the Andaman Sea.

We all love to explore and delve into the unknown, because in fact, the ocean covers about 2/3 of the surface of the globe. There are many underwater landscapes to explore in this vast area.

Krabi is home to more than 100 islands, offering a variety of diving spots. Krabi's special geology causes the saltwater of Andaman Bay to slowly eat away at the rocks and create thousands of nooks and crannies, perfect for eels, giant clams and other fish and invertebrates.

We highly recommend visiting Krabi and exploring this spectacular underwater life. There are many diving schools in Ao Nang, all of which have an excellent reputation. They always invite new students for scuba diving in Krabi.

General information about diving in Krabi:

  • Total depth of most dives: 10-35 meters
  • 60% dive sites require certification: PADI Advanced Open Water Diver certification or equivalent
  • Visibility: 10-20 meters
  • The best season for diving: January to April (because of currents and better visibility)

Krabi offers a variety of dive sites for every level of diver, from caves and wrecks to quiet and peaceful dives. There's something for everyone. Most importantly, be careful not to touch corals, as they are extremely fragile and some species grow at an excruciatingly slow rate of 2mm per year. Many of the larger corals you may see are thousands of years old.

Krabi is home to stunning and beautiful coral reefs, many species of fish and invertebrates, and great sharks. We invite you to explore this amazing underwater world if you are thinking about diving in Asia. But first, it's worth reading some safety information.

1. Is scuba diving suitable for everyone?

Yes, almost anyone who wants to take up diving can do so. There are a few illnesses that may prevent you from diving, but for the most part 99% people have the ability to take up this hobby. The main problem is that if you have a heart problem, it is worth consulting a doctor.

Thailand and Krabi have doctors who work with diving companies in the region, assessing whether divers can do scuba diving in Krabi. So if you don't have time to be examined before you leave, don't worry - a consultation can be obtained locally.

2. I am not certified, can I still scuba dive in Thailand?

Yes, there is a DSD (Discover SCUBA Diving) which is a day trip to a specific dive. With the DSD you will have a diving instructor and no more than 3 other DSD students diving with you. The dive instructor will brief you on safety precautions, breathing, decompression, and what you can see underwater. The dive instructor will not let you dive too deep, so you will be safe.

3. I want to get certified, how can I do it?

All dive operators in Krabi offer a range of certification courses from Bubble Maker (under 12 years old), Open Water SCUBA Diver and all the way up to Dive Instructor Certification. You'll need to decide which level of certification is right for you and then get more information from the operator directly.

4. Is Scuba Diving in Krabi Dangerous

Scuba diving in general carries inherent risks, but 99.9% divers will encounter no difficulty in diving if a number of safety precautions are followed. Check your equipment and dive according to your experience and ability.

Here's that short list of tips to look out for:

Never hold your breath - when you dive into water, your lungs act like a sponge, contracting under pressure and expanding as pressure is released. The water puts pressure on your lungs, and the deeper the water, the more pressure. Everyone knows that when you inhale air, your lungs expand, and when you exhale, your lungs contract.

Diving in Krabi

When you are scuba diving, it is important to always breathe, allowing excess air to escape as the pressure rises or falls. If you hold your breath while scuba diving and are in the process of ascent, your lungs will overexpand because the excess pressure will not be able to leave your lungs. In the unlikely event of holding your breath, there is the possibility of lung damage due to over-expansion, so remember to breathe.

Go up slowly. When you scuba dive, pressure and gases are exchanged in the bloodstream. One of these gases is nitrogen, and because nitrogen is about 70% of the gas we breathe, there is a lot of it. When nitrogen is pressurized into the bloodstream and then you slowly rise to the surface, most of that nitrogen slowly comes out.

In case you ascend too fast from depth, there is a possibility that nitrogen in the bloodstream may remain under the skin, creating small patches of gas. This phenomenon is called "nitrogen poisoning" and can be avoided by climbing no more than 10 meters per minute. Always stop every 5 meters to give all excess nitrogen time to leave the bloodstream at a safe speed.

Check your gear. Scuba diving in Krabi is impossible without scuba gear, so treat it properly. Always check the air in your scuba gear, make sure your partner's gear is also in order, etc. The vast majority of accidents involving equipment are not due to malfunction of the equipment itself, but to divers not knowing how to use the equipment.

Depending on your equipment, check the special instruments for this dive, for example, if you are going on a night dive, make sure you have a main flashlight and a backup flashlight. If you are going on a nitrogen dive, make sure that your scuba tank contains the correct mixture of nitrogen proportions. If you are going to dive with two tanks, make sure that both tanks are filled correctly and connected securely.

Diving in Krabi
Be fit and drink enough water - scuba diving requires adequate physical fitness. It's a sport that takes a toll on any body, so it's always best to treat your body as well as possible to ensure that it takes care of you during the dive. Exercise yourself, eat healthy foods, get a good night's sleep, and don't drink the night before a dive (but drinking plenty of water before and while scuba diving is recommended).

Avoid cigarettes and coffee while diving, and if you don't feel well between dives or before a dive, rest and don't force yourself to do it.

Dive according to ability - Depending on your experience, certification and ability, there are certain depths and dives you can do. It is important that you take it seriously and do not go beyond your abilities. If you have dived in open water only up to 18 meters, but you plan to dive further up to 40 meters, be sure to let your partner or instructor know.

Diving in Krabi

All instructors ask the certification level of all divers during instruction. Do not force yourself to go on a dive - this is often the cause of many diving related accidents when divers go beyond their abilities.

Follow the rule of thirds - always dive safely and make sure you plan ahead. There is a simple rule called the "rule of thirds," which states that you must have 1/3 of the air reserve allotted for that purpose before you start diving or ascent to the surface.

For the return trip, 1/3 of the air should also be provided for that portion of the dive. Finally, 1/3 of the air should be allocated for the ascent. If you leave 1/3 of the air for a safe ascent and make stops along the way, this ensures that there are no unforeseen problems that can arise from the air supply.

Diving in Krabi
Plan your dive - some knowledge and understanding is always required, why it is always better to dive in Krabi with professional knowledgeable instructors and organizers. These people live in Krabi dive sites and know each place like the back of their hand.

Before each dive, the master or instructor will study the dive site in detail to learn about currents, depths and similar factors. It is important that each dive is planned in advance (by the master or instructor) and that all divers listen and ask questions about the dive and understand the entire dive plan and stick to it along the way.

Use the buddy system - diving in Thailand and in the world in this respect recommends that all divers dive with a friend. Unexpected events can happen, so it is always important to have a second diver with you who can help in a dangerous situation.

When you're diving with a buddy, whether a friend or a simple partner assigned to you by your dive instructor, it's important that you talk to them and warn them about any special gear and equipment you may have or problems you may have before diving into the water.

5. How deep can you dive in Krabi?

The entire Andaman Bay covers a range of depths, opening up many dive sites: the shallowest dive sites are around 5-10 meters and the deepest are around 70 meters. The deeper dive sites (over 40 meters) require special diving skills, as the standard PADI or CMAS certification allows divers to go no deeper than 40 meters.

6. I want to do free diving, is it possible in Krabi?

Yes, of course all dive sites in Krabi are open to freedivers, but freediving is a completely different sport than scuba diving. We recommend that you contact an experienced professional freediver who can teach you the skills and peculiarities of the sport before you go free diving on your own.

Our recommended freediving instructor is Brandon Ford Sing, founder of Shark Guardian. He can be reached by cell phone at 0622121544 or by visiting www.sharkguardian.org.
