Koh Rong Samloen Snorkeling with Bioluminescent Plankton

Select Date and Travellers
2 travellers
    What to Expect

    One of the most spectacular sights on a night snorkel is to witness the hundreds of tiny star-like bioluminescent phytoplankton scintillating like a starry sky as you move through darkness. To get the most out of this tour, you need to go in the water with a mask on.
