In short

For certified freedivers, Blue Chitta in Koh Tao offers coach sessions at 2,000 thb — a freediving instructor in the water with you, doing your safety and giving feedback — line training at 1,300 thb for Level 2 certified freedivers with their own buddy, pool training at 1,500 thb, plus guided Reef Freediving Adventures, a marine biology experience, retreats and professional pathways. Most sessions follow the weekly freediving schedule, so you can join flexibly.

What's on offer.

Each path, and what it covers.

  1. Coach session — an instructor freediving with you

    • For any freediver who has completed a freediving course
    • Your coach is a freediving instructor in the water with you, doing your safety on every freedive
    • Personal feedback on technique, equalisation and relaxation, freedive by freedive
    • Improve depth and confidence, refine freefall, prepare for competition or advanced courses
  2. Line training — independent training on the buoy

    • For Level 2 certified freedivers (or equivalent) who can do safety freedives to at least 15 metres and bring their own buddy
    • No instructor on your buoy — you and your buddy are in charge of safety, and a lanyard is mandatory
    • Equalisation and Frenzel technique
    • Freefall and duck dive technique
    • Relaxation at depth and efficient movement in the water
  3. Pool training — breath-hold performance

    • Static and dynamic apnea
    • CO₂ tolerance
    • Relaxation techniques and breath-hold efficiency
    • Mental training and apnea recovery
  4. Pool & dry training — train like a freediver

    • Breathwork and dry apnea training
    • Equalisation exercises
    • Lung stretching and mobility work
    • Nervous system regulation
    • Static apnea tables and mental preparation
  5. Explore rather than train

    • Reef Freediving Adventures — guided reef exploration with experienced guides, no numbers involved
    • Marine Conservation — coral reef ecosystems, marine biodiversity, conservation and reef protection, combined with a guided reef freedive
    • Sail Rock trip — a day of freediving at Koh Tao's famous pinnacle

Better freediving, not just deeper freediving

We think progression comes from more than chasing depth. Our training pairs technical development with mindfulness practices that help you relax, become more efficient underwater, and actually enjoy the process. Whether the goal is equalisation, breath-hold time, new depths or simply more hours in the ocean, the sessions are built around where you are now.

Where it can lead

If you want more than sessions: the certified Freediving Retreat combines daily freediving with yoga, breathwork, meals and sea-view accommodation; the 4-week Master Freediver programme takes you to a professional standard and is the ideal preparation for teaching; and the Instructor course turns the whole thing into a career.

Questions, answered clearly.

The useful details first. Ask the team when your plans need a specific answer.

How much is a freediving line training session in Koh Tao?

1,300 thb for a single session, or 10,000 thb for ten. Pool training is 1,500 thb, and the combined pool & dry training session is 2,500 thb.

How does a coach session work?

Your coach is a freediving instructor in the water with you — freediving beside you, doing your safety and giving you feedback on every freedive. Anyone who has completed a freediving course can book one. A session is 2,000 thb, three are 5,000 thb and ten are 15,000 thb, and you can add a meditation & breathing session for 250 thb or a water therapy session for 1,800 thb.

What is the difference between coaching and line training?

A coach session includes a freediving instructor who freedives with you, does your safety and coaches you — any freediver who has completed a course can join. Line training is independent buoy time for Level 2 certified freedivers (or equivalent) who can perform safety freedives to at least 15 metres and come with their own buddy: there is no instructor on your buoy, you and your buddy are in charge of safety, and a lanyard is mandatory.

Do I have to commit to a course?

No. Most training follows the weekly freediving schedule, so you can join flexibly session by session while still getting structured coaching and professional guidance.

What if I just want to enjoy the reef?

Join a Reef Freediving Adventure — a guided reef exploration for certified freedivers with no structured training, or the marine life and biology experience, which combines a guided reef freedive with education about Koh Tao's ecosystems.

What should I bring?

Just sun protection and a reusable water bottle. Everything else, including all freediving equipment, is provided.
