Koh Mook is one of the most famous islands in the Trang Sea, renowned for the stunning Emerald Cave, a natural wonder hidden within limestone cliffs. Visitors must swim through an approximately 80-meter-long dark tunnel before discovering a hidden emerald-green lagoon and a pristine white sandy beach surrounded by towering cliffs—a truly otherworldly experience.

Beyond the Emerald Cave, Koh Mook also offers several peaceful beaches, such as Farang Beach and Sabai Beach, perfect for those seeking quiet relaxation and a genuine connection with nature.
Koh Mook is a must-visit island, where both the underwater beauty and the charm of the Emerald Cave leave an unforgettable impression.
