Pollution: The Hidden Side of Tulum
FR

Hi Anna, the seawater isn’t exactly inviting for a swim either. As for the cenotes—no way. I can’t even imagine dipping into that. Why bother? What’s the fun in bathing in a sewer? If you’re looking for more detailed info, Greenpeace released a very thorough report in 2016 on pesticide contamination in the cenotes, which is a whole other issue compared to the fecal contamination everyone talks about. It’s in Spanish and titled *Contaminación de cenotes con plaguicidas en la Península de Yucatán*.

Oh, I don’t speak Spanish. Only my husband remembers a bit from school. No, there’s really no pleasure in dipping into a sewer, but I haven’t lost hope of finding a cenote that’s cleaner than the others (and there are still a few of them!).

Hi, laws are cantonal, but you won’t see a huge difference from one canton to another, except with the adoption of the trash bag tax, where each canton implemented it at the time it deemed most appropriate.

I think you’ve made up your mind, but for my part, I went to ask biologists or people working on-site in those cenotes, and they were very reassuring... Sure, there’s pollution we can’t deny, but it’s far from being sewers (there’s still room for improvement!). There’s no health risk. So, personally, I won’t deprive myself of the pleasure of discovering them—maybe more off the beaten path than along the Riviera Maya. That said, to avoid making the pollution worse, skip the sunscreen, deodorant, makeup, and take a good shower first.

Hi Anna, thanks for looking into this. If those people are tied to local tourism, I don’t think they’re being objective. Imagine saying that 75% of the cenotes in Yucatán are polluted—it’d be an economic disaster. Given the number of converging articles, I’d rather check out other places next time and avoid the water this round. Who are these biologists? Greenpeace, whom I particularly trust, released a report that doesn’t seem very positive. And if 80% of Tulum’s hotels dump their wastewater into the ground, I don’t see how a miracle could happen.

No, they're expats who have scientific work, one of them related to the cenotes. That said, I don’t know them personally, and I didn’t question them in depth. 😕 I sent them the scientific articles in English that I found, plus the Greenpeace report, and here’s one of the responses I got: "The water *is* polluted, but mostly by pesticides and cosmetics. If you go to a cenote, I’d recommend not using perfume, deodorant, cream, etc., to avoid polluting them further. And I also see that bacteria don’t thrive very well in this environment."

From what I’ve read, swimming in cenotes is a bit like swimming in a pond or lake in France. The difference with cenotes, though—another response I got: "The water in cenotes is rainwater naturally filtered by the limestone rock (the Yucatán Peninsula is one big limestone rock). The water in cenotes has a pH of 7, and you’ll find the same water in hotel taps or our homes."

I also came across a map of cenotes showing good water quality during my research. Unfortunately, I forgot to save it and can’t find it in my history (I have to say, I scoured the whole web 😮). Anyway, the ones in Cuzamá were marked as clean—I checked because I wanted to go there. Can’t you get away from Tulum and head toward Bacalar, for example? Or visit the Sian Ka’an reserve?

I guess the 25% that’s not polluted is far from towns like Tulum. I’d rather not spend too much time on the road in 10 days. The farthest I’ll go is Valladolid. So around Tulum, I’ll be pretty limited, since I also don’t feel like swimming in the sea in front of those hotels. A pH of 7 doesn’t mean the water’s free of pollution. From all this, I understand that fecal matter ends up in cenotes near towns since the rock apparently filters it, and in the sea (and tap water, since treatment infrastructure seems to be failing and it’s not safe to drink from the tap). But pesticides and chemicals dumped into the sewers end up in most of the interconnected cenotes, tap water, and the sea near human activity. Sian Ka’an is on the plan. Maybe it’s still a little preserved.

Okay, I get not swimming there. But don’t skip visiting some of them—they’re stunning geological formations. Pick them based on that rather than whether you can swim, and you’ll keep some amazing memories. ++ JP

True, seeing it must be interesting even if it’s frustrating. Initially, unaware of the sewage and pesticide issues, I was already hesitant about jumping into a watering hole where thousands of people come to splash around—like a pool with no water treatment.
JP JPwankenobi Regular ·
Yes, but it’s not stagnant water. It’s water in constant motion across—or rather, beneath—the entire Yucatán Peninsula. The network spans thousands of kilometers, and I’m not even talking about the total water volume. Have a great trip anyway! JP.

Hi everyone,

I just got back from 3 weeks in Mexico and came across this heated discussion about water pollution. I’m one of the "fools" who swam in the cenotes..., and despite everything, it remains one of my best memories! They’re geological wonders! There are over 10,000 cenotes in the Yucatán. And not just on the Riviera Maya—quite the opposite, actually. The ones I loved the most are near Valladolid. It’s important to know that cenotes aren’t municipal swimming pools, and very few people actually swim in them, especially the less "mediatized" ones. It’s also up to tourists to follow basic rules, like not wearing sunscreen, avoiding perfumes, etc...

I completely agree that the area around Tulum has become quite a bleak zone, where the thirst for money has taken over authenticity and respect for nature. Seeing those poor dolphins trapped in aquariums for the entertainment of some tourists, or all those all-inclusive hotels along the sandbank in Cancún... it’s disgusting, and that’s exactly what we should avoid and boycott! On the other hand, there are Mexicans, long-time locals, who are just trying to get by by taking advantage of tourism to make a living.

That said, it’s important not to hesitate to venture further to discover places like the Sian Ka’an reserve, which is still preserved, or Bacalar Lagoon, which is still protected from mass tourism—for now, at least, though things are starting to change there too.

I went to Cancún but didn’t set foot in the luxury hotel zone. I was surprised by the Cancún I discovered—its small downtown and "zócalo" that comes alive in the evening, where Mexican families stroll and kids play. That’s another side of Mexico worth remembering: the beauty of its landscapes, the simplicity of its people, the festive and warm atmosphere...

As travelers, we also have a responsibility to travel sustainably and think about the ecological impact we leave behind. But like in any country, I’ve also contributed to Mexico’s land pollution...

Happy travels to those heading to Mexico!

Thanks for your feedback, Joanna. For my part, I’ll also take the usual precautions. We’ve still planned 4 days in Playa since my husband and daughter are into diving (and for my son and me, there’ll be more activities during that time) and 1 day in Tulum for the Sian Ka’an reserve.

Hi everyone,

I’ve been to Mexico countless times since 1985, from northern Mexico City all the way down to Panama. I used to love Mexico City and the colonial towns (my favorite is Oaxaca, but all the others are beautiful too!) and the landscapes, especially the mountains and the people.

In recent years, I’ve been flying into Cancun because I’ve developed a passion for the Mayan sites of Central America, even the smallest ones. Some I’ve visited multiple times, not to mention the new ones—there are still so many buried in the forests.

In 1985, only the beach in Cancun was developed. Since the late '80s and early '90s, I’ve witnessed the insane overdevelopment of the entire Caribbean coast between Cancun and Tulum. (A lot of Spanish investors, among others...) Not to mention the corruption of the Mexican government (and the governor of Quintana Roo, of course), who couldn’t care less about the environment or the locals in favor of $$$$$$$$.

In 1985, Playa del Carmen was a small town (a bit bigger than the tiny village of Tulum) with a ferry dock to Cozumel, a few hotels, and some camping-cabins.

So, I always made a quick stop at the stunning beach in Tulum, south of the Mayan site. Back in '85, there was just one tiny camping-cabañas spot, the Santa Fe, and jaguars crossing the road (personally, I never got lucky enough to see one).

And between Tulum and Punta Allen, until 2012, the accommodations stayed modest in size (though the prices have become outrageous over the years🏴‍☠️!)

Anyway😊, my last swim in Tulum’s sea was in 2012, and the water was crystal clear—I even swallowed a mouthful.

After this long preamble, which probably only interests me😎, it’s clear that the pollution situation could only have gotten worse over the years given the massive scale of this "Riviera Maya" (poor Mayans!).

In short😊, what I wanted to say by jumping into this discussion: if the sea in Tulum is this damaged, then Cancun and Playa del Carmen must be even worse...!!!😕😕

Happy travels to all!

Joanna, I completely agree with you.

I went to Mexico a year and a half ago, and I absolutely loved it, personally. I didn’t just "do" Playa del Carmen or Tulum—those were actually the places I liked the least.

We visited Yucatán, Chiapas, Quintana Roo... and we would’ve loved to go much farther south and west, but we didn’t have enough time there.

So, we saw cenotes—I didn’t swim in them, though—but I found some that were really beautiful, especially Cenote Azul (though nearby Bacalar, I didn’t really love, but that was more because of the place we stayed ^^).

We found Tulum kind of meh after seeing incredible Maya sites in less touristy parts of Yucatán. On some sites, we were practically the only tourists—it was amazing.

Mexico can’t be reduced to Playa del Carmen, Cancún, or Mexico City, thankfully.

And pollution, whatever form it takes, right now, we’re dealing with it everywhere in the world. Unfortunately. Sometimes overthinking things isn’t worth it (and I’m one of those people who overthinks way too much—I’m trying to learn to let go...).

And in the case of the person who started this post, if I were in their shoes and already that disgusted before even going, I’d probably cancel, even if it meant losing the money, because it’s off to a bad start, and I think those would be ruined vacations. What a shame...

Hi Evelyne, I’m the one who started this thread. Two questions:

- You said, "We found Tulum pretty lame after seeing incredible Maya sites in the Yucatán that were way less touristy—on some, we were practically the only visitors, it was amazing." Which sites do you recommend within 150 km of Tulum?

- You wrote, "I didn’t really love Bacalar." For what reason? Just the accommodation?

Thanks!

Seeing all those all-inclusive hotels along the sandbar in Cancun... that just makes me sick, and that’s exactly what you should avoid and boycott!

Good luck...

All the Canadians I know go there, from 7 to 77 years old. To all-inclusives...

When you ask them where they’re going on vacation (they don’t *travel*, they go on vacation), they’ll tell you themselves: « at such-and-such hotel ». The location doesn’t matter, as long as there’s the sea, the sun, and... unlimited alcohol. And if you think I’m exaggerating, do a little research... 🤪

Hi Lionel,

Actually, the thing is, the most beautiful sites—the least crowded ones too—are over 300 km from Tulum, really. 😐😐

Except for Chichen Itza, which is about 155 km from Tulum and absolutely stunning. I don’t know when you’re going, but we were in Mexico in April and May, and honestly, there weren’t crowds, but... it’s best to arrive as early as possible, first to avoid the intense heat (by 10–10:30 AM, it’s *reaaaally* hot) and especially to avoid the tour buses that start showing up mid-morning (I’m talking about the more famous sites like Chichen or Uxmal—no risk of crowds at the others). In April/May, it’s still manageable; they’re not too numerous, but I imagine July/August is a different story.

Otherwise, so many sites were breathtaking, all pretty far from the "Riviera Maya"—I remember Calakmul, Palenque, Misol Ha, Kohunlich, Uxmal... the gorgeous city of Campeche, and so many other places. It’s really a country to explore by taking the time to leave the overly touristy spots and venturing deeper into the country. That said, I can’t guarantee that hygiene standards inland are the same as back home—probably not, though sometimes even back home...

As for Bacalar, yeah, it was mostly the accommodation that disappointed us, and the town too, but we’d just come from much better places. Still, it’s worth seeing the Bacalar Lagoon, and nearby, Cenote Azul (the water is—or seems—so crystal clear, but no pressure to swim ^^). We completely missed visiting Akumal—the turtle beach—because, a bit exhausted from the trip, we just didn’t find it (the shame), but I hear it’s worth it.

Hope this helps a little, anyway!

Hi again, Not far from Valladolid, there’s the Ek Balam site, which I’ll be visiting in April. It’s a "recent" discovery that was uncovered by a team mostly made up of French researchers. The nearby cenote X'canche is stunning.

There’s also Cobá, which personally didn’t wow me that much, but I think that’s because it was the first site I visited, and I was expecting something more like what I’d seen or read about Chichén Itzá. Cobá might deserve a second visit after some time.

I loved Tulum, which is nothing like a religious city such as those you see in Chichén Itzá or Uxmal. It’s an ancient port and trading city that was still inhabited when the Spanish invaded the peninsula. So, don’t expect it to be like its more famous, more "religious" counterparts. It’s perched on a cliff above the Caribbean, the highest point (12-15m) along the coast. The grays of the stones, the greens of the vegetation, and the gorgeous blues of the sea blend together to create a stunning mosaic. Visually speaking, with the layout of the buildings, it’s one of my favorite sites. But hey, there’s the sea, so that’s normal.

Well spotted, well said....

You should always be wary of 'travel sellers.' Tulum has no historical interest; its only unique feature is that it's the only Mayan site by the sea... and ultimately not too far from Cancun's ghettos.... Same goes for Chichen Itza. Meanwhile, Coba and especially Uxmal, Mérida, and the Ruta Puuc have so much to show and tell.... But that’s not what the average tourist is interested in: 'It’s too far from the hotel and the included meals....' 😛

Some guides (like *Le Routard*) never stop raving about the......7 shades of blue in the sea at Bacalar Lagoon.... 😎 Personally, I’ve never seen more than 3, even after several visits. Bacalar is on the way to Chetumal and Guatemala.... In short, there’s what the guides say and then there’s reality. And most importantly, Mexico isn’t (and thankfully!) just the Yucatan...

You're right, I forgot to mention Ek Balam—I actually visited it too and loved it. In fact, I think I loved all the Mayan sites except Tulum. Now, don’t yell scandal, let me explain: I found Tulum stunning as a site by the turquoise and blue sea—it’s truly a gorgeous place. However, and nothing will change my mind on this, unfortunately, I *hated* the hordes of American tourists who don’t hesitate to climb on the remains of monuments, step over ropes to pose next to a "old rock" against the azure backdrop. I also didn’t find the ruins as interesting as all the others I’ve seen, but that’s probably just personal taste. 😊
