By bus
Several bus companies offer routes across the Peninsula to Escárcega, or north to Cancun and other cities on the Mayan Riviera. The main bus terminal, i.e. ADO terminal, where most buses arrive to is located about two kilometers north of the city center in the crossing of Av. Insurgentes and Av. Belice. There's an official taxi stand right outside the terminal, and a taxi to the center costs about 20 pesos.
If you're arriving from Belize, your bus might arrive to the New Market Nueva Mercado. New Market is located about two kilometers northeast of the center, in the corner of 2do. Circuito Periférico and C. Veracruz.
By plane
Chetumal Airport IATA: CTM ICAO: MMCM offers a limited selection of flights to major cities in Mexico. It is also possible to fly into airports across the border, in Belize, and cross by land into Chetumal. Another option is to fly into Cancun or Merida and take a bus from the airport.
By car
Mexico's Federal Route 186 traverses the sparsely populated southern half of the Yucatán between Escárcega and Chetumal. After Ucum, the only municipality with services such as gas and lodging between Escárcega and Chetumal is Xpujil. Federal Route 307 branches off Route 186 to the north towards Cancun, from a point about 30 km west of Chetumal.
