Why Visit:
Long Set Beach, often referred to as 4K Beach, is widely considered one of the most beautiful stretches of coastline on Koh Rong. It is celebrated for its miles of powdery white sand, sparkling turquoise waters, and a tranquil atmosphere that offers a peaceful escape from the busier tourist hubs. Visitors are drawn here for the pristine natural scenery, world-class sunsets, and the rare opportunity to swim with bioluminescent plankton that light up the water like stars after dark.
Activities:
- Beach Relaxation: Spend the day sunbathing and swimming in the calm, shallow waters along the 4-kilometer stretch of white sand.
- Bioluminescent Plankton: Join a nighttime tour or swim in the dark at the quiet ends of the beach to witness the magical glow of underwater plankton.
- Water Sports: Rent a kayak or paddleboard to explore the coastline, or book a snorkeling and diving trip to see local coral reefs and marine life.
- Island Hiking: Explore the jungle trails that connect Long Set Beach to other parts of the island, including the more secluded Long Beach.
- Social Events: Visit the Nest Beach Club, especially on Saturdays for the “Nestival” party featuring games and social gatherings for travelers.
Ticket Price:
Access to the beach itself is free. However, visitors should budget for the following:
- Ferry Transfer: Approximately $25 USD for a round-trip speedboat ticket from Sihanoukville.
- Island Tours: Snorkeling and plankton boat tours typically range from $15 to $30 USD per person.
- Equipment Rental: Kayaks and paddleboards usually cost around $5–$10 USD per hour.
Visitor Tips:
- Cash is Key: ATMs are extremely limited on the island and often unreliable; ensure you bring enough cash (USD) for your entire stay.
- Insect Protection: Sandflies can be prevalent on the beach; bring high-quality insect repellent and coconut oil to protect your skin.
- Stay Hydrated: The Cambodian sun is intense, so carry plenty of water and wear sunscreen, especially during outdoor activities.
- Night Safety: If you plan to see the plankton on your own, bring a reliable flashlight for the walk back to your accommodation.
Best Time to Visit:
The best time to visit is during the dry season, from November to May, when the weather is sunny and the seas are calm. The peak period between December and March offers the most consistent blue skies and clear water, though April and May can be very hot. The rainy season (June to October) is quieter and cheaper but brings frequent downpours and rougher seas that may limit boat travel.
Long Set Beach is a quintessential tropical paradise that perfectly balances natural serenity with enough activity to make it an unforgettable highlight of any Cambodian island itinerary.
