Celestún: Then and Now

By Deborah Van Hoewyk

If you haven’t been to Celestún, you should go – and if you want an object lesson in how tourism can change a small fishing village, go twice, a couple of decades apart. (Not that Bahías de Huatulco doesn’t represent how tourism changes a place!)

Celestún is the head town of the municipio (basically, a county) of Celestún, in Yucatán state; it’s about 105 km (65 miles) west of Merida on the Gulf of Mexico. The Mexican Tourism Secretariat identified Celestún as a place to develop “low environmental impact” tourism, focused on the flamingo nesting sites in local lagoons.

Celestún Then – 2001

When the idea of wintering in Mexico first took hold, a friend’s father who spent his winters in San Miguel suggested that we could get a cheap charter flight to Cancún and explore the Yucatán.

We were neophytes at traveling in Mexico, our Spanish pre-beginner. Our previous, and only, trip had been in 1979, to Veracruz – where burros were staked out in the grassy sand dunes that stretched south to Boca del Rio, and to Jalapa, to visit my ex-pat friend teaching English at the University of Veracruz – pigs roamed the streets. Twenty years later, the sand dunes, the burros, and the pigs, not to mention the boat-up restaurant with drunken singers at lunchtime, were no more.

Going to Cancún, Getting Out of Cancún

The cheap charter was doable, so off we went. At the time, it was possible to book just the flight and not an attached vacation at some glass-towered hotel on the beach. Not interested in Cancún itself, we left the airport in our rental car and headed for Mérida, the capital of the state of Yucatán.

On the road into the centro, hubby John kept saying, “When is this street going to get better?” We clearly didn’t know then that most urban Mexican streets are crowded, dusty, noisy, frenetic. Right in the middle of it all, I said “We’re here!!!” Hopping out of the car and over to a blank but beautiful hardwood door, I entered the quiet lobby of the Dolores Alba hotel. The Dolores Alba displayed its colonial heritage in a lovely arched and beamed dining room replete with chirping bird cages. No street noise. Parking was through a bigger hardwood door next door, but of course John had to circle through chaotic one-way streets to get there.

Then as now, Mérida, and Progreso, north down the road to the beach, had much to offer: colorful Mexican markets, colonial architecture, outlandish beach architecture – some other story. We were bent on Celestún to see the flamingoes – in late winter, it is the largest nesting site in the world, with 25,000 to 35,000 flamingoes. Back then, what little information there was appeared in the Lonely Planet guide, Yucatán. And Celestún was definitely a Lonely Planet experience.

A Visit to Celestún

Driving from Mérida straight west on route 281, we crossed the bridge over a long, skinny lagoon, Riá Celestún, to “downtown” Celestún, located on the beach. A year earlier, in 2000, Mexico had declared the area a “biosphere reserve”; in 2004, UNESCO would make it an international biosphere reserve and the Ramsar Convention, an international wetlands preservation organization, would recognize it as being of international importance. None of this ecological significance was yet evident to visitors.

On the advice of our LP guide, we found a a hotel a block off the beach. Lunch was available on the beach – all you had to do was follow the giant black SUVs from Mérida churning their way through the “streets,” paths bulldozed through the sand. We also checked out how to visit the flamingoes, which entailed going down to the beach in the morning; when a given boat had enough passengers to make it worth their while, the voyage would begin.

By dinner time, the SUVs – and the restaurants – were gone. We drove hither and yon looking for food, ending up in a general store, where we found tinned sardinas, saladitas, and cervesa. Back at the hotel, we discovered that the only source of light to set up the sardine/saltine repast was a naked lightbulb about 8 feet up the wall. It did have a hanging string to turn it on and off.

The next morning, we went early to the zócalo, thinking surely there would be a restaurant. Not so much. Someone in the central market did offer coffee, which turned out to be Nescafé de olla – thinking Nescafe would be quick, I soon learned that, no, the de olla part is brewing it in a pot with a bit of brown sugar and cinnamon, and takes way more time than pouring boiling water over coffee granules. The time, however, allowed us to espy a turquoise door over in the far corner of the zócalo.

To which we proceeded after having our coffee, which was just enough time for the turquoise door to open and reveal a restaurant with a breakfast menu. “Oh, look,” I said, “Poffertjes!” Hubby is Dutch, and poffertjes are Dutch, wonderful little puffy buckwheat pancakes. My poffertje announcement caught the attention of the restaurant owners, a young couple from Delft in the Netherlands. They had come to Celestún a year before, promptly decided this was for them, went home for six months, sold everything they owned, and came back to open the restaurant with the turquoise door.

The Main Attraction: Flamingoes!

Full of poffertjes, we went back to the beach. No one was there yet, so we sat on a driftwood log. Eventually five other people showed up, that was enough, so we helped push the boat down to the waves and got on. I don’t recall that we had to wear life jackets. Not even sure that I recall life jackets at all!

From the beach, the boat captain found a tunnel cut through the mangroves to reach the lagoon. As we headed to where the flamingoes were supposed to be, he pointed out a crocodile perched on what appeared to be a log floating in front of the mangroves. Everyone rose up, sharply tilting the boat towards the water, to take pictures of the crocodillo. We continued on, until a faint coral line appeared along the far side of the lagoon – closer and closer until the line turned into thousands of flamingoes, heads down in the water, feasting on brine shrimp, tiny creatures that give the flamingoes their coral-pink colored feathers. It was an unforgettable sight.

After many, many (no doubt identical) flamingo photos, we set off on our return. The crocodillo was still there, turning lazily in the wind. Somehow the “log” looked more like a very large tire. When we coasted through tunnels hacked through the mangroves to reach our last stop, a petrified forest, I had enough Spanish to ask whether the crocodillo was muerto, and yes indeed it was dead as a doornail. Sort of a home-grown tourist attraction, although I didn’t have enough Spanish to ask how they stuffed it.

On our way back to Cancún (via Chichen Itza), we first went along what’s now called North Beach to inspect a beach house my sister had seen for rent. It was right on the beach, and we filed it away for future reference.

Celestún Later – 2020

We never did rent the two-bedroom beachfront villa, but we did go back to Mérida (the Dolores Alba now has a large swimming pool where the dining room was, and is called “Doralba” – but still lovely and quiet), and again on to Celestún. Mérida is now a stop on the Tren Maya, the pet tourism-cum-poverty-alleviation project of Mexico’s previous president, Andrés Manuel López Obrador. Despite local objections to the Mayan Train’s negative ecological impacts, it has had a major impact on increasing tourism to the Yucatán peninsula – Mérida was the subject of a recent (Feb. 24, 2024) New York Times “36 Hours in …” travel article.

The time we spent in Mérida in 2020 was more akin to the “36 hours” idea than what we did in 2001. Art museums, historic houses, beautiful parks (with ice cream!), and paseo-ing on a boulevard to choose among the upscale restaurants.

After several days of this, we and my sister got in our rental car and went down that same road (Route 281) to Celestún, crossed that same bridge and located our hotel at the beach. This time we had reserved our two rooms in a hotel with a patio, where we were often the only people having wine and cheese (no sardines, no saltines) in the evening. We could walk along the main street and pick a restaurant, or walk on the beach and pick a palapa serving what we call “beach food.”

The Main Attraction: Ecotourism

This time, rather than take the boat tour to the big flocks of flamingoes, we went eco-touristing. The international recognition of the Riá Celestún biosphere and its wetlands (there’s an adjoining reserve of wetlands at the south end of the biosphere that extends into Campeche state, Los Petenes).

We searched out the Guardianes de los Manglares Dzinintún – the Guardians of the mangroves that ring the Dzinintún lagoon. It was a little hit and miss, but we found them. There were a couple of guys hanging out in hammocks; by now, our Spanish was good enough to say we wanted to go on the tour, and ask whether there would be flamingoes. Yes, that was good, come back tomorrow morning, and we would find flamingoes.

The next morning, after a little confusion about who we were and what we wanted, we hiked a bit to get to a “canoe,” more of a flat-bottomed boat than a canoe (they now offer kayaks for self-propelled adventures). The captain poled the boat through the mangroves, which was a great experience, and we did find small groups of flamingoes in the open areas.

We then went out into the lagoon. The boat captain was having some difficulty poling across the lagoon to get to the dock (return trip was a hike through the mangroves). The captain was struggling to pole the boat towards the dock, so John jumped out to pull, and ended up waist-deep in pale gray mud. The captain was probably appalled, but didn’t say a word! With that, my sister and I had no trouble getting out of the boat onto the dock.

On our hike back, mostly on a home-made boardwalk, every time we reached some clean water, the captain had John take off his pants and wash out the mud – it took three days of rinsing them with the hotel hose to finally get them clean.

Developing Ecotourism in Celestún

According to recent (late 2024, 2025) reviews on Tripadvisor, the Guardianes have come a long way. You reserve in advance with a WhatsApp call, and a tuk-tuk type mototaxi picks you up at your hotel. There are bilingual guides (ask in advance), plus the boat captain. The guide points out birds and wildlife, talks about the work of the reserve, and explains how the Guardianes work with other ecotourism organizations around the world. The tour sounds the same – the presentation has been “modernized.”

There is also an ecotourism company called Sheartails Expeditions (the Mexican sheartail (Doricha eliza) is a hummingbird native to Mexico) that started in 2002, after we were there; it was badly damaged by Hurricane Milton in October 2024, but is again offering some tours for birdwatchers; one specialty is a firefly float through the mangroves.

Local Salt Production

We also took a tour, although you can apparently drive there yourself, of the colored, mostly pink, salt pans (charcas). The Maya settled the area around Celestún around 1800 BCE; they produced salt via evaporation and traded it throughout their empire and with other pre-Hispanic civilizations.

Our guide explained the Celestún salt industry; in the early 1900s, the town of Real de Salinas (Royal Salt Mines) was the production site for “dye wood” (Haematoxylum campechianum, or logwood) – a hardwood that can produce red, purple, and blue dye, and for salt. The town of Real de Salinas is now in ruins, although people ride bikes out to see the “ghost hacienda.”

The salt industry that remains in Celestún is small, no longer a major source of income or employment for many of the nearly 7,000 people who live there. There is a women’s cooperative society that produces and sells salts from the reserve (Sociedad cooperative salinas de la reserva); the coop wholesales and resales flor de sal, coarse salt, table salt, and sea salt, which you can buy locally. There is a more commercial product sold by a Cancun company called Gusto Buen Vivir (The Taste of Good Living) – Celestún Flor de Sal Gourmet, “Harvested, Collected, Dried, and Packaged by Hand.” You can buy it on Amazon for $30 USD for 26.5 ounces.

Ecotourism, Tourism, and Celestún

In January 2025, the governor of Yucatán issued a UNESCO-sponsored publication, Yucatán: Mosaicos de Experiencias. UNESCO’s goal is to strengthen the capacity of rural indigenous communities to design and manage their own “community-based tourism” (CBT) experiences; the tourism department of Yucatán state has a capacity-building program to help develop local CBT businesses as an alternative to the mass resort-style
model (really, is the beach in Cancún much different from the beach in Phuket?). CBT gives communities the chance to benefit from tourism experiences they design themselves; the outcome is equitable development that brings market benefits to marginalized local peoples. Both the Guardianes de los Manglares Dzinintún and Sheartails Expeditions are listed among the 14 CBT “social enterprises” in the Yucatán Mosaic catalogue.

And how well is CBT holding up in Celestún? When we first went to Celestún, there were nearly 6,000 people there, although the population rose to 10,000 in octopus fishing season, which begins August 1 (Mexico is one of the world’s largest exporters of octopus, and 98% of that octopus comes from the Yucatán). From 2000 to 2010, the population increased by less than 300 (± 5%), but from 2010 to 2020, it increased by almost 23%, to 8,389.

That population increase comes from migration in search of employment, a typical result of promoting a new tourism destination. Associate Professor of Anthropology Matilde Córdoba Azcárate has studied four tourism sites in the Yucatán, Celestún among them. Córdoba Azcárate looks carefully at how tourism exploits the places, people, and natural resources of any given location “in order to satisfy short-term consumer demands.” Like us, Córdoba Azcárate twice spent time in Celestún, first in the mid-1990s and then in 2002. In the 1990s, she found it was off the beaten path of tourism, but once Mexico defined the biosphere in 2000, and UNESCO recognized that, development started to accelerate. By 2002, the author found “all the trappings of modern tourism” – which limited access to the very natural resources Celestún was trying to merchandise, intensified social conflict, and increased crime and violence.

While development has increased the population, prosperity is not equally shared (please tip your hotel maid), there are not enough jobs to go around, there’s exceedingly limited health care. According to Córdoba Azcárate, increasing tourism has benefited only a few people, and failed to deliver the “promised sustainable and inclusive economic growth.” In our experience in 2020, 18 years after Córdoba Azcárate’s second visit, the situation may have improved – here’s hoping that the Yucatán’s CBT capacity building program for community-based tourism stays alive and well!

Córdoba Azcárate’s book is Stuck with Tourism: Space, Power and Labor in Contemporary Yucatán (Oakland, CA: University of California Press, 2020).

 

It Came from Outer Space –and the Dinosaurs Were No More

By Deborah Van Hoewyk

A long time ago, in an asteroid belt – or maybe a comet cloud – but definitely far far away … a “space rock” escaped its orbit and slammed into Earth. It was the end of an era.

An Astronomical Event
A long time would be 66 million years ago (mya), apparently on a day in the northern-hemisphere spring. The impact marked the end of a geological period called the Cretaceous, which ran from 145 to 66 mya). The Cretaceous followed the Triassic (237- 201 mya) and Jurassic (201-145 mya); these three periods comprise the Mesozoic Era, or the age of dinosaurs. The dinosaurs, except for those that could fly, were pretty much instantaneously over as well.

There is not yet agreement on whether the “space rock,” 9.6 km (±6 miles) in diameter, was an asteroid, basically a giant rock, or a comet, made of ice, rock, and dust. Whether it came from the asteroid belt, a donut-shaped collection of debris left over from when the planets of our solar system were formed, or from one or another of the more distant debris clouds that generate comets, doesn’t really seem to matter. Either way, Jupiter got into the act and set the space rock on course for a place named Chicxulub (chicks-oo-loob) on the Yucatán Peninsula of Mexico.

What did Jupiter do? Exerted gravity. Jupiter is about 318 times the mass of Earth, and its gravitational pull is about 2.4 times that of Earth. As astrophysicist Amir Siraj, a student at Harvard when he did his research on the “Chicxulub Impactor,” explains, “the solar system acts as a kind of pinball machine,” and “Jupiter, the most massive planet, kicks incoming long-period comets into orbits that bring them very close to the Sun.” The complicated interaction of these “sun grazer” comets with solar tidal forces makes them smaller and faster, and increases the chance they’re headed straight for earth.

What Happened the Day the Dinosaurs Died?
About a thousand species of dinosaurs inhabited the earth. From ancestors to extinction, they lasted about 230 million years, with the age of recognizable dinosaurs running for about 165 million years. They originated when the earth had a single land mass, called Pangaea; as Pangaea split into areas we now know as the seven continents, the dinosaurs went along for the ride on most of them.

Mexico hosted a range of dinosaurs, with most fossilized remains coming from northern Baja California and Coahuila. There were horned dinosaurs like the Cohuilaceratops, 4 meters (±13 feet) long and weighing just over a ton – but its horns were 1.2 meters (±4 feet) long. There were some of the largest duckbilled hadrosaurs – remains of Tlatolophus galorum were just unearthed in Coahuila, as well as smaller duck-bills like Velafrons and Latirhinus. Tlatolophus was 8-12 meters (26-39 feet) long, weighing in at about 3.6 tons. There were the “apex predators,” the tyrranosaurs, who preyed on the hadrosaurs; Mexico’s best-known tyrranosaur was the medium-sized Labocania, only 7 meters (23 feet) long and weighing in at a ton and half.

Mexico’s dinosaurs were the first to go when the Chicxulub Impactor hit the tip of the Yucatán peninsula with the equivalent of a 100-million megaton blast – 60,000 times the energy of all the nuclear weapons now in existence – hollowing out a crater ±150 km (90 miles) wide.

The impact generated a core of super-heated – over 10,000 degrees – plasma, i.e., matter that has reached a fourth state, beyond solid, liquid, and gas, basically a gas “soup” of charged ions (positive) and electrons (negative).

This thermal pulse lasted for only a few minutes, but it sent out an air blast, a shockwave of air pressure that created winds well over 1,000 kilometers (600 miles) per hour. The air blast radiated across the seas, sending raging wildfires through ancient forests and bringing tsunamis with waves 100-300 meters (±330-990 feet) over the coastline of the Gulf of Mexico.

The impact also produced a seismic pulse equal to a magnitude 10 earthquake, causing landslides on the sea floor, which was already deeply eroded by the backwash from the tsunamis. The seismic pulse radiated far from Chicxulub, with tremors gathering surface water and pushing it up the Western Interior Seaway, an inland sea that split what is now the United States in two.

All terrestrial flora and fauna, along with marine life, within a 1,500-1,800 km (900-1008 miles) radius was roasted or buried alive. And all of this occurred before any debris ejected from the crater could fall back to earth. Within minutes, however, the debris – mostly rocky rubble and “ejecta spherules” (tiny glass beads called tektites, composed of melted rock and dust) – began falling over the Gulf of Mexico and the Caribbean, covering the end of the Yucatán Peninsula and the adjacent sea floor several hundred meters (±800 feet) deep; 350-600 kilometers (210-360 miles) away in Campeche, at the base of the Yucatán, the ejected debris was 50-300 meters (165 to 980 feet) thick.

Chicxulub and Mass Extinction
The gas, dust, and “geologic shrapnel” flung up by the Chicxulub impact did far more than fall to earth in Mexico. It followed global air currents to create an “impact winter,” in which the entire earth was plunged into darkness and freezing cold as the ejected material circled the globe and blocked out the sun. It was a winter that lasted three years. Hot fragments set off wildfires around the world. Acid rain poured down. Plants died. Animals that ate plants died. Animals that ate the animals that ate the plants died. In what is now called the “Cretaceous-Paleogene Extinction Event (K-Pg),” three-quarters of all species then on earth – including and especially the dinosaurs – went extinct.

Not everyone agrees that Chicxulub is the whole story. After studying over a thousand dinosaur-egg fragments, Chinese scientists have argued that in the two million years before K-Pg, dinosaur diversity was dropping. They conclude that the “end-Cretaceous catastrophic events [saliently massive volcanic eruptions in India that would also have caused climate change] probably acted on an already vulnerable ecosystem and led to nonavian dinosaur extinction.”

There were survivors. Some of the avian dinosaurs, ancestors of today’s birds (not the pterosaurs, though, pterodactyls were actually flying reptiles); early small mammals that lived in burrows; small amphibians like frogs and salamanders; and reptiles – snakes, lizards, alligators, crocodiles, turtles – made it through.

Researchers in evolutionary biology at Cornell University have been studying the ancestors of primates (that’s us!) and marsupials (kangaroos and possums). Before the K-Pg extinction, these mammals had been arboreal, living their entire lives in the trees, not a good place to be as incredibly high temperatures sent wildfires tearing through forests. Right around the time of the impact, however, these mammals were making an evolutionary transition out of the trees and a few survived.

It should be noted that we are now in the “Holocene Extinction,” in which human activity – increasing population, overconsumption, and pollution – threatens the extinction of over a million species in the next ten years; the World Wildlife Fund calls it the “largest mass extinction event since the end of the dinosaur age.”

How Do We Know All This?
You could spend time struggling through academic analyses to gather all this information, but there’s an easier way. David Attenborough, the British dean of natural history documentaries, has just released his latest work, a 90-minute film titled Dinosaurs: The Final Day with David Attenborough (premiered April 15, 2022, on the BBC; in the U.S., May 11, 2022, as a two-part special, Dinosaur Apocalypse, on the PBS show Nova).

The documentary shows Attenborough walking with dinosaurs as the Chicxulub impactor is gathering speed in space (the dinosaurs were created by the animators of The Lion King and The Jungle Book). Surprisingly, the documentary starts out not in Mexico but in Hell Creek, North Dakota, about 3000 km (1800 miles) from Chicxulub. Attenborough spent three years with the researchers at the Tanis dig, and devotes most of the documentary to exploring their findings.

The key? The “K-Pg boundary,” a sharp demarcation between life before, during, and after the impact. At the actual boundary there is a concentration of iridium, a hard, iridescent mineral rare on earth but known to occur in meteorites (meteors are “space rocks” once they have entered Earth’s atmosphere, and meteorites are the post-impact remains of the meteors). In 2016, a group of international marine scientists drilled a thousand feet into the edge of the Chicxulub crater about 30 km (18 miles) northwest of Progreso, Yucatán, extracting a core sample that showed iridium at the point of impact.

The Tanis dig shows this even more clearly. British paleontologist Robert DePalma, working with an international team, found large, astonishingly well-preserved fossils below and in a crumbly layer of rock full of the ejecta spherules. Fossils from the Tanis dig are so well preserved because the post-impact inundation of watery mud engulfed living creatures, preserving them much as volcanic lava preserved the victims at Pompeii in the year 79 CE.

Among these fossils are saltwater fish, obviously not native to North Dakota, with gills full of spherules chemically identical to ones found at Chicxulub, indicating that the fish came with the water that rushed from the Gulf of Mexico up the Western Interior Seaway. It is thought that the spherules may have taken as little as 13 minutes after impact in Mexico to fall in Hell Creek.

Chicxulub and the Future
Will Chicxulub happen again? Probably. But definitely not in our lifetime. Amir Siraj, who identified the sun-grazer comets, has determined that, even though the chances of a similar impact are 10 times greater than previously thought, it’s only projected to occur every 250-730 million years.

In the meantime, Chicxulub has lessons for the future. The crater was open on its northeast side to the Gulf of Mexico, allowing nutrient-rich water to circulate in the crater. Life started up very quickly in the form of microscopic marine life, perhaps within 200 years. A consortium of scientists who study the return of life to Chicxulub say it offers lessons for restoring the oceans, threatened today by oxygen deletion, ocean acidification, and rising temperatures. According to Christopher M. Lowery, of the Institute for Geophysics at the University of Texas (Austin), Chicxulub “might be an important analog for the recovery of biodiversity after we finally curtail carbon dioxide emissions and pollution.”
