Geography
Yucatán covers 39,524 km² of flat limestone, most of it below 50 m. The only relief is the Puuc range in the south, a low ridge whose highest points reach about 210 m. There is not a single surface river in the state: rain drains through the porous rock into an aquifer a few metres below ground, which is why every Maya settlement was built beside a cenote, a sinkhole where the cave roof has fallen in. Several thousand cenotes have been recorded on the peninsula.
Many of them lie on a curve known as the Ring of Cenotes, which traces the buried rim of the Chicxulub crater — the roughly 180 km impact structure left by the asteroid that struck here 66 million years ago, centred on the coast north-west of Mérida. The northern shore, about 378 km of it, is a line of barrier beaches and shallow lagoons: Celestún in the west and Ría Lagartos in the east are protected wetlands where flamingos feed, and the salt flats at Las Coloradas have been worked since Maya times.
The state has 106 municipalities, more than any other outside Oaxaca, Puebla and Veracruz, and the highest share of Maya speakers in Mexico — around a quarter of residents speak Yucatec Maya. Chichén Itzá, in Tinum municipality, is the most-visited archaeological site in the country and has been a UNESCO World Heritage site since 1988; Uxmal and the Puuc route south of Mérida were added in 1996. The henequen boom of 1880–1915, when the fibre was exported through Progreso for binder twine, paid for Mérida's Paseo de Montejo mansions and for the narrow-gauge railways that still cross the plantations.
Main cities
Populations are 2020 INEGI census counts for the whole municipality. Mérida holds more than two-fifths of the state's people; no other municipality reaches 150,000, and Kanasín and Umán are effectively suburbs of the capital.
| Municipality | Population (2020) | Note |
|---|---|---|
| Mérida | 995,129 | Capital, founded 1542; airport MID |
| Kanasín | 139,000 | Adjoins Mérida to the south-east |
| Valladolid | 85,460 | Colonial town 40 km from Chichén Itzá |
| Tizimín | 80,000 | Cattle country in the north-east |
| Progreso | 63,000 | Gulf port and cruise pier, 6.5 km jetty |
| Umán | 60,000 | Industrial belt south-west of Mérida |
| Tekax | 42,000 | Puuc hills, southern citrus zone |
| Ticul | 40,000 | Pottery and shoes; near Uxmal |
| Motul | 37,000 | Former henequen centre |
| Hunucmá | 34,000 | On the road to Celestún |
Mérida is one of the fastest-growing metropolitan areas in Mexico, and the built-up area now runs continuously from Umán through the capital to Kanasín. Away from it, settlement follows the old henequen estates: several hundred villages of a few thousand people each, laid out around a church, a plaza and a hacienda, connected by straight roads that were once rail lines. Yucatán records among the lowest homicide rates of any Mexican state.
Neighbouring states
Yucatán has only two neighbours: Campeche to the south-west and Quintana Roo to the east and south-east. The two borders were drawn across empty bush in the nineteenth century and run largely in straight lines, a rarity in Mexico. The Gulf of Mexico forms the whole northern coast. All three states make up the Yucatán Peninsula, and the Gulf shoreline is part of the Gulf Coast. Because Quintana Roo keeps UTC−5 while Yucatán stays on Central time, crossing that border changes the clock by an hour.
Getting there
Mérida's Manuel Crescencio Rejón airport (MID) is 7 km south-west of the centre and has direct flights to Mexico City, Houston, Dallas, Miami and Toronto. Many visitors arrive instead at Cancún (CUN), 300 km east. By road, Highway 180D is the toll route from Mérida to Cancún, about three and a half hours, with the free Highway 180 running parallel through Valladolid and Chichén Itzá. Highway 261 goes south to Uxmal and on to Campeche, Highway 176 north-east to Tizimín, and a fast road links Mérida to Progreso in 30 minutes. Driving from Mexico City is about 1,320 km and 16 hours via Villahermosa and Campeche. The Maya Train stops at Mérida, Izamal, Chichén Itzá and Valladolid. See the airports map, the road map and the archaeological sites map.
Questions about Yucatán
Where is Yucatán on the map of Mexico?
In the far south-east, on the northern tip of the Yucatán Peninsula, facing the Gulf of Mexico. It borders Campeche and Quintana Roo, and Mérida is about 1,320 km from Mexico City by road.
Why are there no rivers in Yucatán?
The state is a slab of porous limestone with almost no relief, so rain drains straight down instead of running off. The water collects in an underground aquifer that is reached through cenotes — sinkholes where the cave roof has collapsed.
How far is Mérida from Chichén Itzá?
120 km east on Highway 180D, about an hour and a half by car; Valladolid is another 40 km beyond. Chichén Itzá lies in Tinum municipality and is the most-visited archaeological site in Mexico.
What is the best time to visit Yucatán?
November to March is dry and cooler, with daytime highs around 30 °C. April and May are the hottest months, the rains run June to October, and the Gulf coast is exposed to the Atlantic hurricane season from June to November.
