Bioluminescent plankton beaches and tours

You can watch Bioluminescent plankton only where the beach coast is clear of pollution, and there is no light. The glowing plankton comes in different sizes, shapes and colours. The most common colour is blue, and the rare colours include red, orange and green. The intensity with which they glow also varies on many factors. Rapid waves cause motion leading them to react, which greats sparkle in the water. 

Tourists head to the beaches in Koh Rong to see this spectacle. The most popular beach for bioluminescent plankton appearance is Coconut Beach. On the darkest side of this beach, you can witness the shiny plankton that touches the coast and makes the shore look magical.

There are snorkelling plankton tours, where you can snorkel at night to watch the glittering plankton up close. If you make swift motions in the waters while snorkelling close to them, the sparkle of the plankton increases. Although they are harmless, coming in contact with these plankton causes rashes and itch. So you are advised to steer away by tour guides if you opt for snorkelling at night to watch bioluminescent plankton. If you don't want to join any tours but still want to snorkel close to this plankton, then you can rent snorkel gears from the shops close by or from the guesthouses and hotels, which rent it out for a small fee.

How To Reach Bioluminescent Plankton

You can get to the Coconut beach by speedboats from the nearby Koh Touch village. It takes about 30 minutes and costs 25 USD per person. You can reach by walking from Koh Toch as well, and it is a small hike that takes 2 hours. If you are arriving from Sihanoukville, the last ferry back is at 5 PM, so you need to plan accordingly for this night tour.
