OK Club Diving Center

Only technical and cave diving center on Koh Lanta. IANTD/SSI/PADI certified, trimix, decompression courses, deep wall diving at Hin Daeng.

OK Club Diving Center is the only technical and cave diving operation on Koh Lanta, filling a niche that no other center on the island addresses. Holding certifications from IANTD, SSI, and PADI, the center caters to experienced divers who want to push beyond recreational limits and explore the deeper reaches of the Andaman Sea's underwater terrain.

The IANTD affiliation is particularly significant, as the International Association of Nitrox and Technical Divers is one of the world's most respected technical diving agencies. OK Club offers the full spectrum of IANTD technical courses including Advanced Nitrox, Decompression Procedures, Technical Deep Diver, Trimix, and Cave Diving. These programs are led by instructors with extensive experience in overhead environments and deep-water operations, drawing technical diving enthusiasts from around the world.

The deep walls at Hin Daeng and Hin Muang provide outstanding technical diving terrain, with vertical faces plunging well beyond one hundred meters. Technical divers equipped with appropriate gas mixes can explore depths inaccessible to recreational divers, encountering untouched sections of soft coral wall and the deeper portions of the pinnacles where larger pelagic species are more commonly seen. Koh Haa also offers technical diving opportunities, with the deeper sections of the Cathedral cavern system and surrounding walls extending below recreational limits.

Sidemount diving courses are available for divers interested in this increasingly popular configuration, whether for recreational or technical applications. The center maintains technical-grade equipment including stage bottles, decompression cylinders, and facilities for mixing nitrox and trimix on site.

While the primary focus is technical diving, OK Club also accommodates recreational divers through SSI and PADI programs. However, the center's real value lies in being the sole provider of genuine technical and overhead-environment training on Koh Lanta, an otherwise underserved market in this region of the Andaman Sea.
