The region groups renowned archipelagos such as Phuket, Krabi and Koh Phi Phi, known for their turquoise waters and karst cliffs. It concentrates much of the country's beach and diving offerings, from lively beaches to more secluded islands.
What to discover in the Southern Islands of Thailand?
The Southern Islands of Thailand stretch along the Andaman Sea, where limestone cliffs plunge straight into turquoise water. Phuket, the country's largest island, serves as a gateway to a string of quieter islands such as Koh Phi Phi, Koh Lanta and the Similan Islands, famous for their dive sites.
Beyond the beaches, the region offers boat excursions through Phang Nga Bay, hikes to viewpoints overlooking hidden coves, and a lively nightlife in the main beach resorts. Calm waters and coral reefs attract divers and snorkelers year-round, with the best visibility during the dry season.
