What Makes the Water Glow at Night?

This glowing is caused by tiny marine creatures known as dinoflagellates. They are minute planktons which, when disturbed, generate light as a result of a natural chemical reaction. Scientists think that this type of glow keeps them safe by alarming their predators or drawing in larger animals, that can scare off their enemies.

As you swim in the water with your hand, kick, swim with your feet in the water, or with your pin-paddle in a kayak, thousands of these small organisms may flash bright-blue for a few moments. The outcome resembles stars on the bottom of the surface.

This is referred to as bioluminescence and is spotted in various locations around the world. Nevertheless, one of their most favorable locations to observe it in Southeast Asia is Koh Rong Samloem due to its rather dark skies and clean waters along the coast.

Contrary to artificial light performances, all the glowing spangles are by living organisms. It makes the experience even more special since not any two nights look precisely the same.

Best Time to See Bioluminescent Plankton Koh Rong Samloem

Time is a key determinant of whether you get a memorable experience. The glowing plankton may be seen all over in the year, though there are certain conditions when they can be seen much better.

The dry season that usually lasts between November and May, is the most clear in terms of water and has calmer waters. These months offer us a good visibility, particularly on the evening boat trips.

Moonlight also matters. The most brilliant shows are likely to be on a new moon, or where the moon is a mere crescent. The less natural light creates the appearance of a glowing water that looks much brighter.

The optimal nighttime is normally between 8 PM and midnight, but this may be subject to change depending on the situation in the area.

Visibility can also be affected by weather. Clear skies and calm water make good watching opportunities sometimes as compared to windy or stormy evenings.

Nature has no assurances of good conditions and therefore a two night stay on the island will more than likely guarantee you an impressive display.

The Best Places to Experience the Glowing Water

On Koh Rong Samloem, there are various great places where a guest can easily view bioluminescent plankton all the time.

Saracen Bay is the most visited region in the Island as there are numerous resorts and restaurants that make their presence in the beautiful white-sand beach. Some light is produced by the nearby accommodations, however the boat tour tours usually venture in the darker areas of the bay where the light is made very noticeable.

Lazy Beach has a more relaxing environment. It has a minimal development which contributes to reduced artificial lights and so far a favorite place by nighttime nature lovers in the island. Swimming in the dark and later enjoying a tranquil sunset are activities that many visitors love to do.

Another good alternative is Sunset Beach. The trip is rewarding in itself as a scenic stroll through the island can reach the beach. When the night falls the more peaceful environment is usually ideal to observe glowing trails on the water.

There are also some organized boat tours which travel off the shore to more even darker areas. These tours are usually one of the best as they are not affected by the lights in the area, which can decrease the visibility.

A darker location will be a noticeable difference. Even dots of artificial light may diminish the dramatic appearance of the glowing plankton.

What a Night Tour Is Really Like

Guided tours appeal to many of the visitors as it makes the experience easier and safer.

When the boat is at the appropriate place the crew usually requests everybody to turn off phones and not use bright flashlights. This aids in adjusting the eyes of everybody in the darkness.

Part of the tours enable swimming out of the boat. Diving into the warm tropical water tends to be the most important moment as everything you do can give you precipitating streaks of glowing blue around your body.

Kayaking tours give a variety of experience. With every stroke of the paddle, there is a sending out of spurts of water that trail after the kayak. Lots of others call that to be floating among underwater sky stars.

Tours take between one and two hours and in this time the visitors have sufficient time to have fun without being stressed out.

There is a surprisingly peaceful atmosphere. The lack of glaring lights or any loud distracters can see many individuals mere spectators of the glowing water.

Tips for Getting the Best Experience

Your evening might be greatly amusing with a bit of preparation.

One should also respect the sea environment. Plaice, the plankton and are living organisms and thus this special ecosystem will be preserved by not interfering with the organism where there is no need.

Photography may not be an easy task. The cameras of most smart phones are unable to record bioluminescence. Better results can be had with professional cameras using long exposure settings, and those can seldom compare to what your real-life eyes see.

A lot of travelers do not encourage taking pictures but they suggest enjoying the moment.
