Japanese Gardens
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily, so treat everything here as planning ranges.
Sheltered by Koh Nang Yuan's triple islets, Japanese Gardens is the calm, bright nursery where a remarkable share of the world's divers blew their first underwater bubbles. The slope arranges itself politely: fields of branching and brain coral studded with Christmas tree worms, wrasse and damselfish at eye level, butterflyfish pairs on patrol, juvenile angelfish in the rubble, and green turtles that drift through class formations with celebrity effect. Depth barely reaches 16 m and current rarely registers, so skills happen on sand patches while snorkelers float overhead. It is diving with the training wheels visible, and prettier than it has any obligation to be.
The moment you come for: First-dive calm, healthy shallow coral, turtle flybys through training classes
Topography: Gently sloping hard-coral garden on sand
Entry: On the sheltered east side of Koh Nang Yuan's sandbar; reached by boat or as a shore dive from the islet, which charges a landing fee.
Know before you splash
Hazards: Swimmer and longtail traffic off the sandbar; sunburn ranks above everything else.
Conservation: Enormous beginner volume concentrates here; instructors drilling fin control before coral contact is the site's real conservation program.
