Both terminate at Palenque in Chiapas. Travelers should check the security situation in Chiapas with their embassy before attempting this crossing. There is one road border crossing point between Mexico and Belize near Chetumal and Corozal. Getting Around Flights in Mexico are no longer particularly cheap, although flying still represents good value for money, especially considering the long, hot bus trip that may be the alternative. In recent years, the large airlines have left many of the domestic routes to smaller carriers.
Buses are the most common mode of transport and bus routes are extensive.
Local rural buses tend to be ancient, decaying, suspensionless models grinding out their dying years on dirt tracks. Combis, collectivos and peseros are minibuses used for local transport. US driving licenses are valid in Mexico, and driving a car can be a good way to get to some of the most beautiful and isolated towns and villages, although you need to be forgiving of road conditions. Mexican railways have a checkered reputation. Trains are usually cheaper than the bus, but vary between relatively comfortable and downright unsafe.
