Bacalar, Mexico travel guide: the lagoon, getting there by Tren Maya and what it costs

Bacalar is a small town on the shore of a long, narrow freshwater lagoon in southern Quintana Roo, about 40 km north of Chetumal and roughly 3.5 to 4 hours south of Cancún. Go between November and April, when the water is clearest and the "seven colors" of blue show best, and plan on two to four nights. It is quieter and cheaper than Tulum, has no sargassum problem because it is not the sea, and since late 2024 it has had its own Tren Maya station, so you can reach it without a car.

Why the lagoon is worth the trip

Laguna de Bacalar runs for tens of kilometers (sources give anywhere from 42 to 55 km) but is only about 2.5 km across at its widest. White limestone sand and changing depths turn the water from pale turquoise to deep navy within a few meters, which is where the "lagoon of seven colors" name comes from. Its other claim to fame is less visible: it holds one of the largest freshwater stromatolite systems in the world, rock-like structures built by microbes over thousands of years. Tourism has already damaged parts of the colony, and some areas are protected.

That shapes how you should visit. Do not stand on, touch or sit on stromatolites, wherever you see them. Skip sunscreen in the water, or use a mineral, biodegradable one sparingly, and wear a long-sleeved swim shirt instead. Choose sailboat, kayak or paddleboard trips over motorboats.

Getting to Bacalar

By Tren Maya

Bacalar station opened in October 2024 on the line through Tulum, Felipe Carrillo Puerto and Chetumal. Trips from Cancún Airport station take roughly 3.5 to 4 hours with a handful of departures a day, and the short hop from Chetumal takes under 40 minutes. The station sits a few kilometers west of town, so you need a taxi to the center; a fixed fare was agreed in 2025, but expect around 50 to 80 pesos. Check timetables and buy tickets through the official Tren Maya site, since the schedule has changed several times since opening.

By bus

ADO runs direct buses from Cancún (about 4 to 4.5 hours), Tulum (about 2 hours) and Chetumal (about 30 minutes). The Bacalar bus stop is on the highway, roughly 1 to 1.5 km from the main square: walkable with a light bag, otherwise a short taxi ride.

By car

From Cancún, Highway 307 runs south through Playa del Carmen and Tulum; budget three and a half to four hours without stops. A car is useful if you want to visit Mayan sites such as Chacchoben or continue to Calakmul, but you do not need one in town.

What to do

Sail or paddle the lagoon

The classic outing is a half-day sailboat tour that stops at the Cenote Negro (a deep hole within the lagoon), the Canal de los Piratas, where colonial-era pirates once slipped in from the sea, and an island where birds nest. Going by kayak or paddleboard at sunrise, when the water is glassy and the wind is down, gets you the same colors with no engine noise.

Los Rápidos

About 30 minutes south of town, a narrow channel creates a gentle current you can float down. It is run as a private balneario with a restaurant, and the entry fee changes often. This is also the easiest place to see stromatolites up close; look from the boardwalk and do not stand on them.

Cenote Azul

Just south of town on the highway, this is a huge, very deep, round cenote with a restaurant on its edge. It feels different from the shallow lagoon: deep blue and with a steep drop. Pay the entry fee at the restaurant.

Fuerte de San Felipe

The Spanish built this star-shaped stone fort in the 18th century to defend against pirates. It overlooks the lagoon from the center of town and houses a small museum on pirates and the region's history. It is a 30 to 60 minute visit and a good stop on a hot afternoon.

What it costs

Bacalar is moderately priced by Riviera Maya standards. Prices below are typical ranges reported in 2026 and vary by season and operator, so confirm locally.

Item	Typical price
Hostel dorm bed	$10 to $20 a night
Budget guesthouse	$25 to $60 a night
Mid-range hotel on the lagoon	$80 to $180 a night
Shared sailboat tour	800 to 1,500 MXN per person
Kayak rental	100 to 150 MXN an hour
Paddleboard rental	150 to 250 MXN an hour
Cenote Azul entry	Around 50 to 100 MXN
Los Rápidos entry	Around 150 to 250 MXN
Bicycle rental	80 to 150 MXN a day

Cash in pesos is still useful for small operators, taxis and entry fees. Town has a few ATMs, but they can run dry at busy holiday weekends, so arrive with some cash. Our guide to avoiding ATM fees abroad covers which withdrawal option to pick.

When to go

• November to April: the dry season, with the clearest water and the most reliable colors. January and February bring steady breezes that suit sailing.
• Christmas, New Year and Semana Santa: the busiest and most expensive weeks, when Mexican families fill the town. Book early.
• May to October: hot and humid, with afternoon storms. Heavy rain can cloud the water for days. This is also the Atlantic hurricane season; watch forecasts and buy travel insurance that covers weather disruption.

Where to stay

Staying near the fort and the main square puts restaurants, tour operators and the lagoon within walking distance. Hotels along the lake shore south of town give you a private dock and quieter nights but usually need a taxi or bike to get into town. Look for places that show their own access to the water and say they keep guests off stromatolite areas.

Before you go

Check the Tren Maya timetable shortly before you travel, bring a swim shirt instead of relying on sunscreen, and leave at least one early morning free to be on the water before the wind picks up. Combine Bacalar with Chetumal or the Mayan sites in southern Quintana Roo, or use it as the quiet end of a trip like our 7-day Yucatán by Tren Maya itinerary.
