Phuket Cruise to Koh Lanta the diving region located in the southern Andaman Sea between the Phi Phi Islands and Hin Daeng - Hin Muang.
Koh Ha, which means '5 islands' in the Thai language, are tiny islets located 25 km west of Koh Lanta Island. The channels that separate the islands are over 50 metres deep and the water is usually clear with good visibility.
25 kilometres south of Koh Ha is Koh Rok, which are the twin islands known as Koh Rok Nai and Koh Rok Nok and are separated by a thin 15 metre deep channel. All these islands are situated within the Mu Koh Lanta National Marine Park and are uninhabited, boasting stunning unspoiled beaches. The coral reef at Koh Rok is one of the prettiest and well-preserved for diving in Thailan
