Bioluminescent plankton are tiny marine organisms that produce a natural light when disturbed. When the water is moved—by swimming, splashing, or the movement of the boat—the plankton emit a bright, glowing blue or green light, creating an almost otherworldly effect. The phenomenon is most visible in clear, calm waters on dark nights, and Cat Ba’s beaches and surrounding bays are some of the best spots to see it.
-
Evening Departure: After sunset, we’ll meet at the dock and take a boat ride to a location where the plankton are most abundant.
-
Boat Tour: Relax on board as the boat moves through the waters, and your guide will explain the science behind bioluminescence.
-
Swim in the Glowing Water: Once at the right spot, you’ll have the chance to jump into the water (if you wish) and experience the phenomenon up close as the plankton glow around you with every movement.
-
Return to Cat Ba Town: After an unforgettable experience, the boat will return to Cat Ba Town. The tour usually lasts around 4 to 5 hours, depending on the tides and the visibility of the bioluminescence.
What’s Included
- Comfortable boat ride to and from the bioluminescent plankton hotspots
- Guide to explain the natural phenomenon and ensure your safety
- Life jackets for all passengers

What to Bring

The bioluminescent plankton are most visible during the warmer months, from April to October, and the best time to see them is on clear, dark nights with little moonlight.
