Laguna de Manialtepec is a coastal lagoon on the Pacific coast of Oaxaca, Mexico, known for its stunning bioluminescent waters and rich biodiversity, offering unique opportunities for kayaking, birdwatching, and ecological exploration.
Laguna de Manialtepec is a coastal lagoon located approximately 17 kilometers west of Puerto Escondido, in the state of Oaxaca, Mexico. This lagoon is part of an ecologically important system that supports a diverse range of flora and fauna, including mangroves, coastal wetlands, and tropical dry forests. The lagoon’s shallow waters, fed by both freshwater springs and tidal influences, create a vibrant habitat for fish, crustaceans, and migratory birds such as herons, pelicans, and frigatebirds. One of the most remarkable natural phenomena at Laguna de Manialtepec is its bioluminescence, especially visible on warm, moonless nights when microorganisms in the water emit a blue-green glow activated by movement, attracting visitors for nighttime boat tours or kayaking in the glowing waters.
Historically, this area has been significant to local indigenous communities and continues to support fishing and eco-tourism. Recreational opportunities revolve around water-based activities including kayaking, birdwatching tours, and guided ecological walks along the lagoon’s shores and surrounding mangrove forests. The lagoon is also recognized for its importance in environmental education and conservation efforts, as it forms part of larger biosphere reserve initiatives in the region. Visitors are drawn by the ease of access from nearby Puerto Escondido while enjoying a peaceful natural environment that contrasts the busy Pacific tourist hubs.
Landmarks near the lagoon include the slabs of mangrove-covered shores and small sandy beaches lined with tropical vegetation, offering spots for wildlife observation and photography. The Laguna de Manialtepec provides a mild climate and calm waters, making it an ideal destination for families, nature photographers, and eco-tourists looking to experience the fragile coastal ecosystems of southern Mexico.
