Board a traditional longtail and trace Krabi’s limestone islands—snorkel coral gardens by day, dine at sunset on Poda Island, then experience the eerie blue of plankton on a night snorkel at Koh Raeng. A full-day, hotel-transfer-inclusive trip for snorkelers and sunset chasers.
More ways to explore the area's outdoor wonders
The longtail’s diesel cough fades as the sun slips behind limestone towers; warm salt air pushes against your face and the boat eases into a bay rimmed with white sand. Guests step into blue-green shallows to meet the reef: parrotfish nibble, anemones flutter, and a pale green turtle may glide past before disappearing into coral ribs.
