Bacalar

Forty-two kilometres of lagoon in seven shades of blue, living stromatolites and not one tower hotel, four and a half hours south of Cancún.

What it is, and what it is not

Bacalar is not a beach: it is fresh water. A forty-two-kilometre lagoon fed by cenotes, over a white sand floor that throws back seven different blues depending on the hour. The town fits into ten streets, and an eighteenth-century fort looks out over the water from the middle of it.

What almost nobody says before you book: the colour depends on the sun, and one cloudy day turns the whole lagoon grey. Sunscreen is banned at Los Rápidos and at most of the swimming spots. And the lagoon is fragile: the stromatolites that make it unique break under a footstep.

The places

Six stops, north to south

They run in the order you work down the shoreline, from the channel to the bay.

Lagoon Canal de los Piratas
01 / 06
01 Lagoon Canal de los Piratas The northern end, where the lagoon narrows into a turquoise channel half a metre deep. You get there by boat from town. Boat access only 30 min from town
02 Fort Fuerte de San Felipe Built against English pirates in the eighteenth century and now the town museum. From the rampart you see all seven blues at once. Small museum On the plaza
03 Cenote Cenote Azul Ninety metres deep right beside the lagoon, the water almost black from sheer depth. It is the coldest swim of the trip. 90 m deep 5 min from town
04 Stromatolites Los Rápidos A channel where the current carries you gently between banks of living stromatolites. No sunscreen and no standing on the bottom: these colonies are thousands of years old. Sunscreen-free 20 min from town
05 Lakeside village Xul-Ha The south shore, where the people who work in Bacalar actually live. Plain jetties, kayaks at dawn and no tour coaches. 15 min from Bacalar Empty sunrises
06 City and bay Chetumal The state capital, on the Belize border. It is useful for the airport, for the Maya culture museum, and for not a great deal else. Belize border 40 min from Bacalar
When to go

The lagoon has four seasons

Here the month sets the rain, the price and the hours of sun that give the water its colour.

The best December to April Dry, with steady sun nearly every day and cool nights. Also the priciest season, and the only one in which the town fills up. —Book two months ahead —Holy Week: prices double
With a caveat May to August Heavy heat, afternoon storms and mosquitoes at dusk. In exchange, low prices and no sargassum at all: this is fresh water. —Repellent after dark —Swim in the morning
Risk September and October The peak of hurricane season and the wettest months of the year. Several businesses in town shut for weeks at a time. —Flexible cancellation —Grey days in a row
Good value November The rain eases off, the town reopens and prices have not climbed yet. The most usable window of the year. —Best value of the year —Climbs sharply from 15 December
Getting around

Legs, times and prices

Everything arrives by bus. A car only helps if you want the south shore at your own pace.

Cancún (CUN) → Bacalar 4 h 30 $28 ADO Direct bus from the airport, several departures a day. The longest leg, and the one most people take. Chetumal (CTM) → Bacalar 40 min $5 colectivo The nearest airport, with flights from Mexico City. Colectivos every half hour. Tulum → Bacalar 3 h $18 ADO Highway 307 heading south, straight and in good repair. The Maya Train covers the same run. Mérida → Bacalar 5 h 30 $32 ADO One overnight bus and two daytime ones. Useful for chaining the peninsula without going back to Cancún. Bacalar → Mahahual 2 h $14 Bus as far as Limones, then a combi to the coast. By car it is an hour and a half, direct.

Reference prices in dollars gathered in 2025, per person, economy class. ADO sells online and at the town terminal; the Maya Train also stops at Bacalar.

Where to sleep

Four bases, four different trips

See hotels →
From $80 The lakefront Small hotels with their own pier over the water. For swimming on waking and never touching a car for three days.
From $45 The town Around the fort and the two plazas, everything on foot. For eating cheaply at night and reaching the water through the public swimming spots.
From $60 South shore and Xul-Ha Quieter, greener and with fewer boats going past. For dawn paddling, if you accept depending on a taxi to get anywhere.
From $40 Chetumal Plain city hotels with no charm, but cheap and always open. For one night before an early flight or the crossing into Belize.
Before you book

What everybody asks

At Los Rápidos and most swimming spots, no: you will be asked to shower before going in. Elsewhere on the lagoon, only oxybenzone- and octinoxate-free. A long-sleeved rash top solves the whole problem.

No. Sargassum is a marine seaweed and this is a landlocked freshwater lagoon. It is the reason many people come this far south between May and August, when the Caribbean coast is having a bad time of it.

Yes, mainly along the mangrove edges and in the northern channels. They are not at the town piers or at Los Rápidos, and there have been no incidents with visitors; even so, stay out of murky water at dawn and dusk.

Three is the honest minimum: one for the lagoon by boat, one for the cenotes and Los Rápidos, and one spare in case a day comes out cloudy. Five if you are adding Mahahual or southern Quintana Roo.

Not for the town, which you can walk across in twenty minutes. It helps for the south shore and the roadside cenotes, though a taxi per trip works out cheaper than three days of rental.

Between ten and two, with the sun high and directly over the water. First thing the lagoon is glassy and better for paddling, but the seven blues do not show up until the sun is full on it.
