Did you know that many of the Ao Nang Islands hide a secret for adventurous divers?
Beyond their dramatic limestone cliffs — home to nesting birds and giant bats — lies a network of stunning underwater caves, refuges for incredible marine life.
In this mysterious environment, you’ll often encounter bamboo sharks, blacktip reef sharks, nesting fish, and even rays gliding through the shadows.
Join Cortex Freediving’s Caves Training & Exploration Trip to perfect your skills, capture unforgettable photos, and experience the thrill of freediving through one of the Andaman Sea’s most unique underwater landscapes.
