Long Set Beach is one of the most beautiful and peaceful coastal escapes on Koh Rong, where soft white sands, crystal-clear turquoise waters, and lush natural surroundings come together in remarkable harmony. Also known as 4K Beach, its long stretch of pristine coastline offers plenty of space to walk, relax, swim, and enjoy breathtaking views of the sea. Once home to Khmer fishing communities who depended on the surrounding waters and forests for their livelihoods, Koh Rong has gradually welcomed tourism while preserving much of its natural beauty. Today, Long Set Beach offers a refreshing island experience where pristine nature, local heritage, and peaceful tropical life come together.
Visitors can enjoy a variety of relaxing and adventurous experiences at Long Set Beach, from walking along its long stretch of soft white sand and swimming in the calm, shallow waters to kayaking and paddleboarding along the coastline. The peaceful sea makes the beach especially suitable for families, children, and travelers seeking a relaxing escape.
Explore the surrounding trails and viewpoints, or capture breathtaking sunrise and sunset views across the sea. When natural conditions are right, visitors may also join a guided evening trip to witness the magical glow of bioluminescent plankton illuminating the water at night. With its spacious coastline, crystal-clear waters, and tranquil atmosphere, Long Set Beach offers an unforgettable experience of nature, relaxation, adventure, and tropical island beauty.
Long Set Beach is situated on the eastern coast of Koh Rong, in the Gulf of Thailand, off the coast of Sihanoukville, southwestern Cambodia.
The beach can be reached by a high-speed boat from Sihanoukville, with the journey taking approximately 30-45 minutes, depending on sea and weather conditions. Known locally as 4K Beach, Long Set is surrounded by white sandy shores, crystal-clear waters, and lush tropical landscapes, making it a beautiful coastal destination for experiencing the natural charm of Koh Rong.
