Long Set Beach on Koh Rong Island is a great spot to see bioluminescent plankton! These tiny organisms emit an ethereal glow when disturbed, creating a magical light show at night.

Here's what you need to know:

• Visibility: Bioluminescent plankton are best seen on nights with little to no moon. The darker it is, the better you'll be able to see their glow.
• Timing: Head to the beach after sunset, ideally around 7:00 pm onwards.
• Location: While bioluminescent plankton can be found around Koh Rong Island, Long Set Beach is known for having good concentrations due to minimal light pollution.
• Experience: The best way to see the plankton is to wade into the water and gently disturb it. You'll see the plankton light up around your feet and hands! Some people recommend wearing a snorkel mask for an even more immersive experience.

Here are some additional tips:

• Be aware of your surroundings and stay in shallow water at night.
• Avoid using flashlights or bright lights on the beach, as this can disrupt the plankton's glow.
• Be respectful of the environment and don't use any chemicals in the water.

With a little planning, you can have an unforgettable experience swimming with bioluminescent plankton on Long Set Beach!
