Koh Phangan is a lush, mountainous island in the Gulf of Thailand, about 100 km north of Koh Samui. It has a split personality: the south coast is famous for the Full Moon Party at Haad Rin, drawing tens of thousands of revellers every month, while the north and west coasts remain genuinely quiet, with jungle tracks, secluded bays, and fishing villages that feel a long way from the party scene.
The island rewards exploration. Bottle Beach on the northeast can only be reached by longtail boat or a steep jungle trail, and it still feels undiscovered. The west coast village of Chalok Lam has a working fishing harbour, a coral reef for snorkelling, and a calm, friendly atmosphere. Ang Thong National Marine Park — a cluster of limestone islands with emerald lagoons — is a popular day trip by boat from the island.
In the mountainous interior, the Than Sadet Waterfall draws visitors to a national park where several Thai kings carved their initials in the rocks. The west coast bays of Sri Thanu and Haad Son have developed a yoga and wellness scene that sits comfortably alongside the fishing boats.
Koh Phangan sits about 450 km south of Bangkok, reached by overnight train or bus to Surat Thani and then ferry.
