Sai Kaew Beach

Sai Kaew Beach is Koh Samet's most well-known stretch of coastline, drawing visitors with its bright white sand and clear waters just a short ferry ride from the mainland port of Ban Phe in Rayong province. The beach sits within Khao Laem Ya – Mu Ko Samet National Park, which means an entry fee applies for foreign visitors upon arrival on the island. Its accessibility and natural setting have made it consistently popular among both Thai and international travellers. The atmosphere here leans lively rather than secluded. Speedboats are a regular presence on the water, and the beachfront is lined with sun loungers, vendors, and restaurants serving fresh seafood and cold drinks. An upscale resort sits directly adjacent to the beach, offering a more comfortable base for those who prefer amenities close at hand, though independent accommodation options are also available nearby. Practically speaking, Sai Kaew Beach tends to be at its busiest during Thai public holidays and weekends, when crowds from Bangkok make the roughly two-hour drive to Ban Phe. Visitors seeking a quieter experience are better served by arriving on a weekday or travelling outside peak season. The beach is best suited to those who enjoy a social, activity-filled seaside setting rather than solitude. Bringing cash is advisable, as many smaller vendors and ferry services on the island do not accept cards.
