The bioluminescent plankton in Koh Rong is a stunning natural phenomenon. You can only see it at night, and it shows up best when there's no moon and you're away from any light pollution. You can book a boat tour for around US$10 per person and enjoy the fascinating scenery of twinkling lights all around you as the plankton radiate.

Where to see Bioluminescent Plankton in Koh Rong

We highly recommend the Long Set Resort, located on the stunning Long Set Beach, which is perfectly situated for plankton viewing at night. It's possible to swim with the sparkling plankton and indulge in a unique magical experience.

A word of warning though: swimming at night can be a risky endeavor. Observing the beauty of the glowing plankton from the safety of a boat or the beach is a better bet.
