Koh Samet Beach

Situated off the coast of Rayong in the Gulf of Thailand, Koh Samet is a popular island destination known for its relatively accessible location — roughly 200 kilometres from Bangkok — making it a favoured weekend retreat for both locals and international travellers. The island sits within a national park, which has helped preserve much of its natural shoreline, and the beaches here are characterised by fine white sand and calm, clear waters suited to swimming and relaxing. Visitors can expect a range of atmospheres depending on which stretch of beach they choose. The main beach areas, particularly along the eastern coast, offer a mix of beachside bars, seafood restaurants, and sun loungers, while quieter coves further south provide a more secluded experience. Water activities such as snorkelling and kayaking are readily available, and the island's compact size makes it easy to explore multiple spots in a single visit. Good to know: Koh Samet is accessible by ferry from Ban Phe Pier in Rayong, and as the island falls within a national park, an entrance fee applies to foreign visitors upon arrival. The island is generally drier than much of Thailand during the rainy season, which makes it a practical choice when other coastal destinations are affected by weather. Visiting on weekdays or outside Thai public holidays is advisable for those seeking a quieter experience, as the island draws significant crowds during long weekends.
