Koh Phangan for Groups
Koh Phangan draws solo travellers and couples, but it also makes a lot of sense for a group. The island is small enough that everyone stays connected — you can split up for an afternoon and reconvene for dinner without any logistics drama — and varied enough that a group with different interests can each find something worth their time.
The Full Moon Party is the most famous reason a group might come, but it is far from the only one. Group retreats in Sri Thanu, shared boat trips out to Ang Thong Marine Park, a zipline through the jungle canopy, a Thai cooking class that doubles as an activity and a meal — these are all things that work distinctly better with company. And the island's social infrastructure, particularly around Haad Rin and the west coast, is genuinely geared towards people who travel together.
