Blue Immersion is located on Sairee beach, most popular area in Koh Tao. Our students start their freediving training in our relax classrooms with a beautiful sea view. Relaxation is a big part of the sport, feeling well with the surroundings will help you reaching high performances. When a freediver hold his breath, there is nothing more motivating than the sound of the waves from the ocean. Our freediving courses are conducted in small groups. Our instructors will ensure that each of you leaves with a full understanding of freediving and high performances.


Our outdoor seating area is a great place for our freedivers. We use it for stretching, meditation, lunch and to hang out after the training is over. Our early morning stretching/meditation sessions are important for freediving. It allows our freedivers to gain thoracic flexibility rapidly and achieve greater depth safetly. Eating healthy food is a boost for freediving. Our body gain endurance to low levels of oxygen and allow us to hold our breath much longer. You can enjoy freediving with us without feeling bloated. Sandwiches, salads, thai dishes, vegetarian/vegan food and snacks are available. After the training, we might also enjoy some cold beers looking at the sunset.


A nice set up is essential to practice Freediving safely! Freedivers must have access to training dive sites comfortably to be 100% rested before their dives. The boat need to be back on shore without transferring beginner freedivers to a other boat in case of a emergency. Those of you who knows freediving understand that we feel much more confident if we know that our safety is guaranteed. We freedive Koh Tao with a catamaran built and designed especially for freediving trips and depth training. Our boats bring students from dive sites to shores. It is equipped with 2 competition arms which allow a easier descent and ascent for our advanced freedivers. Also it allow us to train variable weight and no-limit disciplines. We have access to most dive site within 10-15minutes. Catamaran are extremely stabble which really minimize the risk of seasickness compare to classic boats. The Blue Immersion vessel is simply a freediving platforms with engines. It makes our Freediving school the most well-equipped and safest in Thailand!

Having fun is an important key to learn and improve Freediving. When we are happy, our body produce more pleasure hormones such as serotonine, endorphine and others. Those hormones help the freedivers to ignore uncomfortable feelings such as the urge to breath, high pressure and hypoxia. This is why at Blue we take care of your Freediving training and your Thailand experience. To do so we organise dinners, BBQ, nights out, movie nights and apnea games at Blue Immersion. We also give you opportunities every year to meet the very best Freedivers in the world. In 2017 we had the pleasure hosting the former World Champion in constant weight, Guillaume Nery. We also hosted the World Champion of static apnea, Branko Petrovic.
