More people learn to dive on Ko Tao than almost anywhere on the planet, and the economies of scale show: an Open Water course here costs less than a weekend of European lift passes, often with basic accommodation thrown in. Shallow bays like Ao Leuk suit snorkellers; whale sharks make cameo appearances at Sail Rock. Shop around the schools in person and pick small class sizes over the cheapest price.
