This is bioluminescence in the Manialtepec Lagoon , a natural phenomenon that seems like something out of a dream and occurs in very few places in the world.

What is bioluminescence and why does it occur in Laguna Manialtepec?
Bioluminescence is a natural phenomenon produced by microscopic organisms, primarily plankton, that emit light when disturbed. This phenomenon is so unusual that those who experience it describe it as one of the most magical moments of their trip.
Manialtepec Lagoon , located just minutes from Puerto Escondido, is one of the best places in Mexico to observe this natural spectacle. The mix of fresh and salt water, along with the climatic conditions and ecological richness, allow this phenomenon to occur frequently between the months of May and October , considered the best season to experience bioluminescence.
What is the best time to see bioluminescence?
The best time to see bioluminescence is at night, just after sunset and before midnight. Although the phenomenon can be observed under a full moon, the best times to do so are when the sky is darker, as the contrast allows the flashes of light on the water to be more intensely appreciated.
