Why Visit Koh Rong?

Located off Cambodia's southern coastline, Koh Rong and its sister island Koh Rong Sanloem are defined by miles of secluded white sand beaches, crystalline coral reefs, and vibrant jungle interiors.

Whether you seek quiet sunset hammocks on Saracen Bay, bioluminescent plankton swimming after midnight, or kayaking through coastal mangroves, the archipelago offers an ideal slow-travel coastal sanctuary.

  • 2 Bioluminescent Plankton Night Swims: Take a midnight boat trip out to unlit coves to witness glowing marine plankton underwater.
  • 3 Koh Rong Sanloem Lazy Beach & Saracen Bay: Walk the jungle trail across the island from sunrise Saracen Bay to sunset Lazy Beach.
  • 4 Snorkeling & Coral Gardening: Explore healthy coral gardens at Koh Koun reef populated by parrotfish and sea anemones.
