More people learn to dive here than anywhere else: warm, shallow, calm bays and a school on every corner keeping prices honest. Give it 4 days and you leave with PADI Open Water Diver, plus a skill your body keeps long after the tan fades.

Start here. Pull a thread.

  1. More people learn to dive here than anywhere else: warm, shallow, calm bays and a school on every corner keeping prices honest. Koh Tao isn't a single school teaching this either - it's a real cluster, with 2 water & sailing options here, usually a sign of a genuine local tradition rather than a tourist add-on.
