Millions of bioluminescent dinoflagellates
The lagoon’s brightness comes from dinoflagellate phytoplankton—sea-born microorganisms that reproduce in these waters and emit light through a chemical reaction when disturbed.
A motor canoe through mangrove channels
Participants board a motor canoe and enter the lagoon’s mangrove channels to watch the water light up along the hull and paddles, an intimate way to experience the bioluminescent display.
Certified guides with local expertise
Certified guides accompany the trip, providing scientific context and interpretation so visitors can understand the organisms and the ecosystem behind the glow.
