The world's highest-volume dive-training island: go zero-to-pro on one small island, then work as a guide almost anywhere. Give it 8 weeks and you leave with PADI Divemaster, plus a skill your body keeps long after the tan fades.

  1. The world's highest-volume dive-training island: go zero-to-pro on one small island, then work as a guide almost anywhere. 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.
