exercise increased caution
A wide brown lagoon edged with mangroves, and a small boat that slowed down, and there across the water stood a great pink crowd of birds on thin legs, all talking at once. Deeper in, a clear cold spring bubbled up through the brown. Back in the village, painted fishing boats were pulled up on the sand, and lunch was whatever had come in that morning. I asked for seconds.
The short answer
Celestún is a town in the north-west of Yucatán state, Mexico, just north of the border with Campeche, and the seat of the municipality of the same name, Wikipedia records. It is mostly a fishing town: it had just under 6,000 people in 2000, and the infobox gives 6,269 at the 2005 census, and its population swells to 10,000 in the octopus season. Tourism makes up a growing share of its economy. Round it lies the Ría Celestún Biosphere Reserve, which Mexico designated in 2000 and which spans the states of Yucatán and Campeche; UNESCO recognised it in 2004. The Ramsar Convention’s register lists it as wetland site no. 1333, designated on 2 February 2004, with an area of 81,482 hectares, the same 814.82 square kilometres that Wikipedia gives.
Why it's worth knowing
A pink winter crowd. The reserve is the winter home of vast flocks of flamingos, Wikipedia’s article on the town says; its article on the reserve gives the American flamingo population as able to reach more than 23,000 birds, among more than 304 bird species identified there. Travel guides give November to March as the season to see them, with January and February the busiest months (indexed).
Fresh water meeting the sea. “Fresh water from subterranean aquifers have an outlet in the site,” the Ramsar register’s summary says, describing a complex of mangroves, seagrass beds, small estuaries, coastal dunes, hypersaline lagoons and karstic caves. Wikipedia adds that the fresh water mixes there with salt water from the Gulf of Mexico, and that the estuary is part of a mangrove corridor known as the Petenes mangroves. Road building has disrupted the flow of water through some of the mangroves, it records, and a restoration project is working on 217 hectares of degraded mangrove.
The field notes
Salt, fish and a saint at sea
The Ramsar register lists fishing, tourism and salt extraction as the human activities in the reserve. Wikipedia’s article on the town says Celestún has produced salt since pre-Columbian times, a claim it marks as needing a citation. The town has a nineteenth-century lighthouse and a church from the colonial period, and at Holy Week its patron saint is floated out to sea surrounded by candles, Wikipedia records.

- Go out on the water early, in the smallest boat you can find, and ask it to go slowly.
- Watch the pink crowd from wherever the boatman stops. (I tried to write down what they were saying. The list filled up with honking, and has not been quite the same since.)
- Fishing is the town’s work. Walk round the boats on the beach, not between them, and let the town feed you at lunchtime.
- Put a hand into the clear spring among the mangroves, and feel it come up cold.
- Stay for the sunset on the long beach, shoes off.
A pink feather, dropped by one of the flamingos on the estuary. The flamingos of the Ría Celestún are American flamingos, Phoenicopterus ruber, and Wikipedia’s article on the reserve gives their population as able to reach more than 23,000 birds. Its article on the species says most of the bird’s plumage is pink, with red wing coverts and black flight feathers, and names the Petenes mangroves of the Yucatán, the mangrove corridor the estuary belongs to, as an example of its habitat. The feather floats where it fell, and stays there.
Tally, in the marginI took it for a scrap of pink paper caught in the mangroves, and was reaching to tidy it away when the whole crowd across the water opened its wings at once. I saw then whose it was, and that it had been a feather all along. I left it floating where it was, in case anybody wanted it back.
Getting there
How to get there. By road from Mérida, the capital of Yucatán, about 90 kilometres to the east, by travel guides’ figures (indexed); the boats for the estuary leave from the town and from the bridge at its entrance.
When to go. In winter, for the flamingos (above). Canada’s travel advice for Mexico (last updated 19 October 2026) gives the Atlantic, Caribbean and Gulf hurricane season as early June to the end of November, and warns that coastal waters can be dangerous and that riptides are common.
What to arrange ahead. As of 20 October 2026, the boat trips onto the estuary are bought on the spot: a 2026 travel guide puts a trip of an hour to an hour and a half at about 1,800 pesos for the whole boat, for one to six people, payable only in cash (indexed); no official price list or reserve fee could be read. Go early in the day, and on a weekday if you can.
Safety. As read on 22 October 2026: the State Department’s advisory feed gives Mexico Level 2, “Exercise Increased Caution”, dated 29 May 2026, because of terrorism, crime and kidnapping; it says some areas have increased risk and points to its maps of restricted areas. Its country page, which carries the detail by state, refused the request, so no state-level wording was read. Canada’s travel advice for Mexico (last updated 19 October 2026) says to exercise a high degree of caution, and its list of states to avoid for non-essential travel names neither Yucatán nor Quintana Roo.
