You step off the dive boat and the Andaman-tinged water greets you like a cool, waiting breath. Sunlight threads through the surface; below, slopes of coral and bommies fall away into blue that feels like a small universe. This two-day advanced freediving course launched from Koh Chang pushes athletes from comfortable shallow dives into controlled, deeper experiences—target depths between 16 and 24 meters—where encounters with reef life happen in tighter, quieter frames.

You step off the dive boat and the Andaman-tinged water greets you like a cool, waiting breath. Sunlight threads through the surface; below, slopes of coral and bommies fall away into blue that feels like a small universe. This two-day advanced freediving course launched from Koh Chang pushes athletes from comfortable shallow dives into controlled, deeper experiences—target depths between 16 and 24 meters—where encounters with reef life happen in tighter, quieter frames.
Koh Chang (literally "Elephant Island") sits off Thailand’s eastern coastline in Trat province. The island’s volcanic and sedimentary underpinnings create steep drop-offs and patch reefs that attract diverse fish life and occasional turtle sightings. Local villages have long combined fishing and coconut farming; today small piers and wooden longtail boats remain part of the working seascape alongside dive operations.
Expect a curriculum that builds on basic freediving skills: longer static and dynamic breath-hold work, depth technique, safety protocols, and guided deeper dives from the boat. Instruction focuses on relaxation, equalization, and efficient finning to conserve oxygen, plus surface-safety procedures and buddy-team drills.
Practically, bring a well-fitted mask and low-volume snorkel, a comfortable freediving suit or thin wetsuit for warmth during long surface intervals, and a dive computer or freediving watch if you have one. Hydrate well, avoid heavy alcohol the night before, and disclose any respiratory or cardiovascular conditions—medical fitness is central to safety. If the itinerary includes national park sites, a small entry fee may apply. For serious breath-hold progression in warm tropical water and rich reef scenery, this course gives both structure and open-water miles to deepen your practice.
Yes—this advanced course builds on basic freediving skills; participants should hold an entry-level freediving certification or demonstrate equivalent experience.
The course focuses on dives between roughly 16 and 24 meters, with progressive depth training under instructor supervision.
Often yes; some dive sites around Koh Chang are in Mu Ko Chang National Park and may require a small entry fee payable locally.
