Where to swim with Bioluminescent Plankton? That magic of glowing waves… It almost seems like an optical illusion. The surreal phosphorescent world of Avatar is actually not that far from reality. Bioluminescent plankton can create similarly astonishing scenes. Dubbed as ‘Tears of the Ocean’ or ‘Sea of Stars’, the neon-glowing waves can be seen around the world, exclusively by night. And the fantastic thing is that you can experience the magic on your own skin!

Glowing plankton can also be experienced in Maldives


The luminous sea is caused by a chemical reaction of marine plankton (also called fireflies), as a result of which the microorganism emits radiant light. As this reaction is used to evade predators and acts as a defence mechanism, it only occurs when the plankton is being stressed.

Therefore, in very calm waters it is only visible when manually triggered, e.g. by swimming, moving and swirling the water, whereas at the open ocean beaches the neon-blue sparkles can be seen as the waves break on the shores.

Although the bioluminescent plankton lives in all world`s oceans, the phenomenon is best seen in calm, warm waters at cloudy nights. Swimmers should keep moving as much as they can (or even dance and paint with the light) to surround themselves with a perfect ‘Avatar World’ where to swim with Bioluminescent Plankton.

Scuba divers and snorkelers will enjoy the glittering underwater tornado at its best – in absolute dark. Note that the plankton bites and it is extremely difficult to capture it with a camera.

Glowing plankton can be seen at many beaches throughout Australia. Jervis Bay is one of them, and if you stay at one of the local campsites on a cloudy night, you can enjoy the water fireworks from your beach chair.

Similarly, the Gippsland Lakes in Victoria is an area known for sparkling midnight waters but if you like to have a swim in the ‘sea of stars’ you will need to travel in the summer months (Dec-Feb).

Tasmania is also home to bioluminescent plankton, and especially the fans of fishing will enjoy the sea light show in the Preservation Bay.

In 2008, The Guinness Book of World Records officially declared the location where the brightest glowing plankton on the planet can be seen – it is Puerto Rico. Namely, Isla de Vieques is a place where to ‘go with the glow’, and the best way is on a kayak.

Every paddle and splash will agitate the fireflies and result in water turning electric neon-blue,  which almost looks like a special effect. The phosphorescent waves are the major attraction in the Mosquito Bay, and there are numerous tour operators offering various ‘bioluminescent packages’ – the best time is during a new moon night.

Looking like The Milky Way in water, Japan`s Toyama Bay is visited by thousands of blue magic enthusiasts each year. Each midnight, the aluminising shores of Toyama fill with photographers and tourist boats between March and May so they can observe and capture the surreal images.

Travellers who are interested in learning all about the sparkling algae should also pay a visit to the Hotaruika Plankton Museum. Other very cool bioluminescent algae location is Okayama.

There is plenty of night sea kayak tours to the Indian River Lagoon (Cocoa Beach) where you can enjoy the blue water fireworks from above, but there is no need to spend a cent if one doesn`t like to.

Navarre Beach is a beautiful, clean and not very crowded place where the ‘liquid version of the Aurora Borealis’ occasionally lights up in neon blue in the summertime (May-Sep). Otherwise, Cortez Beach is a good spot for a midnight summer swim in a sparkly ocean, too.

Similarly to Florida, also California provides fantastic seasonal ‘sea of stars’Summer often brings the bioluminescent plankton close to the shores of San Diego. This is the time of a year when the tides in the Mission Bay, La Jolla Cove and Torrey Pines Beach glow blue at night, and everybody is free to feel it, swim in it and try to paint with the sparkly light; the darker the night sky, the more spectacular the aquatic show!
