Bioluminescent lagoons

Puerto Escondido

Moonless nights in Puerto Escondido are the best time to swim in the fluorescent waters that light up when the sun goes down. This phenomenon is known as bioluminescence and is produced by microorganisms that shed light when they feel attacked. One of the best places to witness it is in the Laguna de Manialtepec (Manialtepec Lagoon), located just 11 miles away from Puerto Escondido.

The best way to visit Manialtepec is to hire a guided tour. It begins with a sunset boat tour of the mangroves; sunset is, after all, the perfect time to take in the flocks of birds returning to their hidden nests by the lagoon. Within minutes of the sun setting, you'll be able to see the first flashes of neon, in shades of blue, green, and purple. Afterward, you can jump in and swim in the lagoon.

Another popular spot in which to experience bioluminescence is the Lagunas de Chacahua National Park, which is about an hour away from Puerto Escondido, en route to the El Zapotalito community. In addition to nightly swims in its five freshwater bodies, the park also boasts leatherback and olive ridley sea turtles.

The Crocodile Biological Center offers an opportunity to interact with biologists and to support them in the tasks of monitoring and measuring the reptiles. Discover the labyrinths of red mangrove inhabited by more than 130 species of aquatic birds -such as the pink spoonbill and the anhinga duck- aboard a motorboat.
