Ría Lagartos Biosphere ReserveEstablished in 2004 and listed as a UNESCO Biosphere Reserve, Ría Lagartos protects a 60,348-hectare mosaic of coastal ecosystems at the eastern end of the Yucatán Peninsula. The site includes mangroves, small estuaries, coastal lagoons, dunes, marshes called petenes, savanna and several types of forest, and much of the area is also designated under the Ramsar Wetlands Convention.
The reserve is notable for its high biological productivity in a karst coastal setting and supports more than 2,400 plant taxa and over 550 vertebrate species, including many nesting sea and marsh birds. A core protected area is surrounded by buffer zones where local communities carry out traditional livelihoods such as fishing, salt extraction and small-scale agriculture.
Visiting usually involves short boat trips from coastal villages, walks along tidal channels and watching bird colonies from hides or boats; nearby villages such as Río Lagartos and Las Coloradas (pink salt ponds) provide bases for excursions. The territory also contains archaeological traces of pre-Hispanic Maya occupation and a mosaic of human-managed landscapes where ecotourism is promoted alongside fishing and salt work.
- Mangrove channels: Shallow boat trips through winding mangrove channels bring you close to aquatic life and bird colonies that use the estuaries.
- Coastal lagoons and estuaries: Open lagoons and tidal flats are productive feeding grounds for many species and offer wide reflective views at dawn and dusk.
- Las Coloradas salt ponds: The nearby pink-hued salt ponds at Las Coloradas are photogenic and illustrate the area’s traditional salt-extraction economy.
- Birdwatching: The reserve’s wetlands host numerous sea and marsh birds, with breeding colonies visible from boats or viewing points.
- Local fishing villages: Río Lagartos and neighboring villages show local coastal life and are practical launch points for guided tours.
