Long Set
Long Set Beach, often referred to as 4K Beach, is located on Koh Rong island in the Gulf of Thailand. The gently sloping beach is good for swimming and features a much quieter atmosphere than the bustling Koh Touch area. Snorkelers can find corals near the rocks at both ends of the bay. After sunset, the bioluminescent plankton draws visitors to the shore, glowing blue when the water is disturbed. Access is typically via a ferry from Sihanoukville to Koh Touch, followed by a 40-minute jungle walk or a short taxi boat ride. The dry months between December and April provide the most reliable weather for a beach holiday. Over recent years, several bungalow resorts have been established along the bay, providing direct beach access.
