Phuket is Thailand's largest dive hub, serving as the gateway to the Similan Islands, Hin Daeng, and Richelieu Rock — some of Southeast Asia's finest sites. The island's own reefs around Racha Yai and Shark Point offer easy day-trip diving. World-class liveaboard departures, massive operator competition, and resort infrastructure make it incredibly accessible.

Honest reality check

What your dive shop won't tell you

The minimum certification printed on a brochure is the legal floor, not the honest recommendation. Here's what we actually think you should bring to this site.

Recommended logged dives

60+

Below this we'd send you somewhere easier first.

Recommended certification

Advanced Open Water

“Intermediate minimum — deep profiles and variable viz.”

What will challenge you

→Moderate currents. Expect to drift — this is not a skill-builder site for a first trip after certification.
→Recreational limit of 40 m is reachable here (max depth 40 m). Gas planning and NDL tracking matter.
→Wreck penetration requires Wreck specialty training at minimum, and often decompression planning. Don't improvise inside.

Shoot here

Photography brief

Subjects are only half the shot. A perfect macro site is useless in a three-knot drift, and a wide-angle dream is useless at 35 m with a murky ceiling. These are the conditions, not the hype.

Macro subjects65

Wide angle76

Viz stability60

Hover friendliness55

Natural light48

Recommended kit

→Wide-angle or fisheye (8-15mm range), dual strobes for close-focus wide angle
→Dedicated video light for dark wreck interiors; don't rely on strobes alone

Choose Splurge for premium operators, private guides, and top-tier accommodation — worth it for special trips or non-diving partners.
