village of Tabasco State, Mexico
El Ceibo is a pair of border towns in the Petén department of the Northern Lowlands of Guatemala and Tabasco, Mexico.
This town marks the northern most border crossing between Mexico and Guatemala. It is referred to by the same name on both sides of the border. However the Mexican side used to be known Sueños de Oro.
On the Guatemalan side you will find a couple of hotels, stores, and restaurants. The Mexican side is significantly sparser and contains only an even smaller strip of restaurants and shops. If you want to change money it appears doing it on the Guatemalan side is your best bet, as there isn't anybody offering those services on the Mexican side.
There don't appear to be any cross border services across this border.
Guatemala: There are mini-vans or collectivos from El Naranjo in Guatemala, which is about 20 km away
Mexico: There is a daily bus directly from Villahermosa via Emiliano Zapata (4 hours, M$400). Also there are hourly buses from Tenosique (1 hour, M$40).
If you choose to, you can also stay on the Guatemalan side of the border where there are a couple of hotels. However, on the Mexican side, there is really nothing.
