The estuary is the main draw of the Celestun Biosphere Reserve. Thousands of Caribbean flamingos feed in these shallow waters during the winter.
Freshwater from underground aquifers mixes with the saltwater of the Gulf of Mexico here. This mix supports Artemia salina crustaceans, which give the flamingos their pink color.
You must take a guided boat tour to explore this area. Motorized lanchas typically hold up to 6 passengers and navigate the open lagoon, bird sanctuaries, and historic salt flats.
30-45 minZoom lens needed
This primary expanse of water serves as the main feeding ground for the flamingos. The brackish water is rich in the crustaceans they eat. Guides keep the boats at a distance to avoid stressing the birds. Bring a camera with a good optical zoom or binoculars for clear views.
15 minBest in winter
This sanctuary sits within the estuary. It supports large populations of pelicans, cormorants, and egrets. Visit between mid-November and early March to see the highest density of birds. During these winter months, migratory species share the island with resident populations.
15 minWater level dependent
Local communities have traditionally harvested salt from these pink-hued flats. The shallow areas offer a distinct landscape adjacent to the main waterways. Your ability to explore them closely depends on the current water levels. The shallow depths require careful navigation by your boat guide.
