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 a 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.
