Starting at Cortex Freediving on East Railay Beach
The adventure kicks off at Cortex Freediving, tucked behind the “Diamond Plaza” sign, with coordinates 8.012718200683594, 98.84288024902344. The setting is casual but professional, with multilingual instructors (English and French) ready to guide you through your learning journey. The small group size ensures plenty of individual attention, which is crucial when mastering skills like breath control and relaxation.
Learning the Freediving Basics
The early part of the course introduces the fundamentals: how your body functions when diving, proper breath-hold techniques, relaxation methods, and the basics of equalization. These lessons are designed to make you comfortable, laying a solid foundation whether you want to pursue freediving further or just enjoy the initial thrill of holding your breath underwater.
Confined Water Practice
After grasping the theory, you’ll move into pool sessions. Here, practice sessions focus on breath-holding, finning, and body positioning. We loved the way guides emphasize relaxation, which is key to feeling confident and safe underwater.

The 2-day course introduces a real highlight: open water diving. You’ll experience your first shallow dives with a buddy, applying what you’ve learned in a natural setting. It’s the moment where the skills become real, and the marine scenery makes every second special. The open water session is designed to be safe and supportive, fostering confidence in your diving abilities.
Certification and Flexibility
Opting for the 2-day option grants you an official certification, a great perk if you’re considering future freediving or just want a badge to show your achievement.
