The Triple Frontier brings together Brazil, Argentina and Paraguay, separated by the Iguaçu and Paraná rivers. Crossing is routine for visitors to Foz, but every crossing involves immigration control and, on the way back, customs control.
This section brings together what tends to change: documents, rules for minors, vehicles, shopping allowance and official time. Each piece of information shows the official source and the date it was verified. When the review period expires, the site warns that the information may be outdated.
Time in the three cities
Brazil (Brasília time) and Paraguay run on UTC−3, according to the sources in the box above. Time changes depend on each government’s decisions; that is why the clock on the home page uses the official time zones that your browser keeps up to date, instead of a fixed offset. If your trip depends on exact times (flights, timed-entry tickets), also check the official Argentine time.
