The caves accessible by kayak or bamboo boat have formed over millions of years due to water erosion and the gradual dissolution of limestone by rainwater and tides. These natural archways were once hidden from the world, known only to local fishermen who used them as sheltered spots during storms. Over time, these hidden entrances became famous among travelers for their otherworldly beauty and secluded charm.

Many of these caves lead into enclosed lagoons, often called “hong” or “ho” in local language, where legends tell of mythical sea creatures and hidden treasures. Traditional bamboo boats, still rowed by skilled local women and men, keep this cultural heritage alive, offering tourists a glimpse of the community’s long-standing connection to the sea. Kayaking emerged later as an adventure sport, attracting thrill-seekers from around the world. Today, both experiences are celebrated as eco-friendly, low-impact ways to enjoy and preserve these fragile ecosystems.
