A community vote opened today on tulumtimes.com with one question about where to swim in Tulum once you leave the sand behind. Cenotes, lagoons, canals, all of it counts.
There is no shortlist. Readers write in the place they would actually send a friend, and the ranking builds from those answers instead of from an editorial pick made in advance.
The timing is not accidental. Sargassum has been arriving heavily along the Quintana Roo coast through this season, and the question we hear most, in Spanish and in English, is where the clear water went. It did not go anywhere. It sits inland, and most of it sits underground.
No shortlist, no nominees picked by us
The ballot is open on purpose. Most roundups of this coast recycle the same handful of names, article after article, until a visitor arrives with a list that three other visitors are already standing in line for.
This one starts empty. What qualifies is any place a person can get into the water and enjoy the day, a cenote with a ladder and a shade tree, a lagoon with a dock, a stretch of canal you drift down, a spot with a kitchen attached so the swim comes with lunch. Vote for the venue, not for a coordinate on a map.
Readers can also leave a comment explaining the choice, and that part matters more than the tally. A vote gives us a name. A comment tells us why somebody drives 20 minutes past a closer option to get there.
Tulum's freshwater sits under the town
The Yucatan Peninsula is a limestone shelf, and rain has been dissolving it for millions of years. The result is a network of flooded caves running under the whole region, and where a cave roof collapses, a cenote opens. Two of the longest surveyed underwater cave systems in the world, Sac Actun and Ox Bel Ha, run within reach of Tulum, and the second of those extends beneath the coastline itself.
That geology is the reason the question in the vote has an answer at all. Sargassum is a marine alga that travels on Caribbean currents and stops where the sea stops. It has no route into a cenote fed by an aquifer, and none into the freshwater lagoons that sit behind the coastal road. The canals cut through the wetlands of the Sian Ka'an reserve, some of them carved by Maya traders long before anyone booked a hotel here, are fed by the same system.
Which is to say the town has a second coastline. It simply runs vertically instead of along the horizon.
Where to swim in Tulum while the crews clear the coast
The beach work continues in parallel. On Saturday, roughly 150 people from the municipality, the state government, Zofemat Tulum, the Secretaría de Ecología y Medio Ambiente, the Secretaría de Marina, and the neighborhoods around Playa del Pueblo pulled close to 50 tons of sargassum and solid waste off one stretch of sand in a single morning. Similar operations have been running along the coast for weeks, and the hotel sector has asked for the offshore containment that would stop the algae before it lands.
None of that changes what a visitor does with a free Tuesday. The practical answer for anyone here this month, and for the residents fielding the same question from guests, is that the freshwater options are open, cool, and largely unaffected by what happens at the shoreline.
Some of those places have been absorbing that demand quietly all season. We would rather hear about them from the people who go than assign a ranking ourselves.
Vote on the site or through Instagram
Two ways in. The ballot lives on our site and takes under a minute, at this link. Readers who spend more time on Instagram than on news sites can vote and comment through @thetulumtimes, where the same question is running.
Both channels feed the same count. Neither one requires anything beyond a name and, if you feel like it, a sentence about why.
The tally only works if enough people fill it
A vote with 30 entries produces a list. A vote with several hundred produces something closer to an actual map of where this town goes to get in the water, built by residents, workers, and repeat visitors rather than by an algorithm ranking whoever paid for the placement.
The ballot is open now, and it stays open while the entries come in. If the spot you would defend in an argument is not on it yet, that is because nobody has typed it in.
