Things to do in Bacalar.

By road, Bacalar is about 345 km from Cancún, 4.5 to 5 hours, and about 215 km from Tulum, roughly 2 and a half hours, so it pairs nicely with a stop in Tulum on the way. The Tren Maya stops in Bacalar too, and an hourly connector bus takes you from the station into town for about 25 pesos (2025). Flying? The closest airport is Chetumal's, and Chetumal is about 38 km away, around 40 minutes by car; most of its flights go to and from Mexico City.

The drier months are the sweet spot, and April is usually the driest of all. June to October is the rainy stretch, with September the wettest; after heavy rain, runoff can dull the lagoon's blues near shore for a few days (in July 2025 it was back to normal in 3 or 4 days). Hurricane season runs June 1 to November 30 and is busiest mid-August to mid-October, so check the forecast the week before if you come then.

Two nights at least, because Bacalar is slow by design. A good rhythm: arrive on day one, spend day two on a lagoon boat tour, and use day three for a kayak, a swim at Cenote Azul, which is over 300 m across, or the Chacchoben ruins, open 9:00 to 17:00. Head out on day four. Bacalar is about 215 km from Tulum, roughly 2 and a half hours each way, which is why a same-day trip feels rushed.

You can swim in the lagoon, and an easy place to start is the Balneario Ejidal, right on the shore, where you can also kayak. Cenote Azul, over 300 m across and up to 90 m deep, is great for a swim and a snorkel. The lagoon is also home to stromatolites, living rock where only the top 5 cm or so is alive: admire them from at least 3 m, and skip sunscreen in the lagoon, even the biodegradable kind.
