The intense pink color of the local flamingos is derived from their diet of Artemia salina, a brine shrimp that thrives in the hypersaline waters.
The reserve protects the 'Petén' ecosystem, which consists of islands of tropical vegetation surrounded by flooded savanna.
It is one of the few places in Mexico where you can observe all four native mangrove species: red, black, white, and buttonwood.
The area is home to one of the largest concentrations of nesting sea turtles in the region, particularly the Hawksbill and Loggerhead species.
The hypersaline water in the Las Coloradas section creates a natural 'pink lake' effect due to the presence of carotenoid-producing microorganisms.
The reserve has been recognized as a Wetland of International Importance under the Ramsar Convention since 1986.
In 2004, the reserve was officially designated as an Important Bird Area by BirdLife International.
Reserva de la Biosfera Ría Lagartos is a 60,348-hectare protected wetland ecosystem located on the northern coast of the Yucatán Peninsula. It serves as the primary nesting site for the largest colony of American flamingos in Mexico. The reserve consists of a hypersaline estuary system characterized by a unique mix of fresh water from subterranean aquifers and seawater from the Gulf of Mexico. The area encompasses diverse habitats including mangroves, coastal dunes, petén forests, and tropical savannas. It is a critical stopover point for thousands of migratory birds traveling along the Central Flyway. The reserve is strictly managed under a conservation mandate to protect fragile ecological zones. Visitors access the reserve primarily by small boat tours through the winding mangrove channels. The high salinity levels in specific sections of the estuary result in naturally occurring salt crusts and distinct color variations in the water. Local conservation efforts are centered on balancing sustainable ecotourism with the protection of endangered flora and fauna.

Use polarized sunglasses to see beneath the surface of the estuary water.
Apply biodegradable sunscreen only, as chemical lotions damage the delicate aquatic ecosystem.
Bring a waterproof bag for cameras and electronics, as boat spray is common during transit.
Book official local guides to navigate the restricted zones and gain access to protected observation points.
Do not attempt to feed the flamingos or other wildlife, and avoid using drones, as they are prohibited due to the stress they cause to bird colonies.
Access to specific nesting colonies is restricted during the peak breeding season; boat tours are suspended during periods of severe tropical weather.
Maintain a strict distance from wildlife, keep voices low to avoid disturbing nesting birds, and do not touch the salt crusts or walk on fragile dune vegetation.
