Getting there & away
There are eight daily buses from Porto Alegre to Sânto Angelo (US$30, 7½ hours).
It’s possible to enter Argentina by crossing the Rio Uruguai from Porto Xavier to San Javier, or from São Borja to Santo Tomé, or at Uruguaiana, 180km south of São Borja (with buses to Buenos Aires). But if you’re heading for the Argentine missions, more frequent buses (seven daily) depart from Puerto Iguazú (across the border from Foz do Iguaçu) for San Ignacio Miní (US$24, five hours). For the Paraguayan missions, daily buses go to Encarnación from Ciudad del Este, Paraguay, also opposite Foz do Iguaçu.
