Krabi has over 100 islands with some of Thailand’s most magnificent diving sites, known for its azure blue shores, idyllic limestone mountains and warm water. Owing to excellent underwater visibility, diving is one of the best ways to see submerged caves, coral reefs and colourful fish up close. Anyone can learn diving and scuba diving at Krabi’s diving schools and centres, such as in the Ao Nang Local Islands, Gypsy Divers, and Railay Dive Centre.
