Imagine slipping into the darkness of night and watching every movement in the water wake flashes of light. That is bioluminescence at Manialtepec Lagoon, a natural phenomenon that seems drawn from a dream and happens in very few places in the world. Puerto Escondido is one of those privileged spots where you can witness this natural wonder, thanks to the bioluminescent plankton living in its waters.
What is bioluminescence and why does it happen at Manialtepec Lagoon?
Bioluminescence is a natural phenomenon produced by microscopic organisms, mainly plankton, which emit light when they are disturbed. It is so unusual that those who experience it describe it as one of the most magical moments of their trip.
Manialtepec Lagoon, only minutes from Puerto Escondido, is one of the best places in Mexico to see this natural show. The mix of fresh and salt water, together with the climate and the ecological richness, means the phenomenon occurs regularly between 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. The phenomenon can be seen during a full moon, but the best moments are when the sky is darkest, since the contrast makes the flashes of light in the water far more intense. During the trip you'll also enjoy the starry sky, as Manialtepec Lagoon is an ideal place for stargazing too.
