About Laguna de Manialtepec
The Manialtepec lagoon is about 15 km west of Puerto Escondido, separated from the sea by a sandbar. It is roughly 7 km long and is surrounded by mangroves where herons, cormorants, kingfishers, pelicans, spoonbills and many other birds live.
Early in the morning boat tours travel the mangrove channels to observe birds, and some continue to the sandbar where the lagoon meets the Pacific.
At night the lagoon is known for bioluminescence: microorganisms in the water emit a bluish light when the surface is disturbed by the boat, oars or hands. The phenomenon is usually stronger between July and December on moonless nights, and it varies greatly from one night to another.
Tours are run by cooperatives and local operators, by boat or kayak.
