Ko Samet

Sitting in the Gulf of Thailand off the coast of Rayong, Ko Samet is a national park island known for its powdery white sand beaches, calm and clear waters, and accessible coral reefs. Its relatively compact size makes it easy to explore, and its proximity to Bangkok — around three hours by road and ferry — makes it a popular weekend escape for both locals and international travellers looking for a genuine beach experience without a long-haul journey. The island offers a range of beach settings, from livelier stretches with beach bars and water sports to quieter coves where the pace slows considerably. Snorkelling is a draw for those wanting to explore the reef life just offshore, and the clear waters make for comfortable swimming across much of the year. Accommodation and dining options are spread across the island, catering to a range of budgets and travel styles. As Ko Samet falls within a national park, visitors are required to pay an entrance fee upon arrival. The island is busiest on weekends and Thai public holidays, so those seeking a quieter experience are better served by visiting on weekdays or outside peak season. The driest and calmest weather typically runs from November through to April, making this the most reliable window for beach and water activities.
