Welcome to San Ignacio
The best preserved of the Argentine missions, San Ignacio Miní is the central attraction of this small town north of Posadas. You could visit from Posadas or on your way to Iguazú, but making this a stopover appeals: there are some decent places to stay, and you’ll have a chance to check out the excellent sound-and-light show at the ruins. San Ignacio is a good base for visiting other mission ruins, both in Argentina and Paraguay.
San Ignacio is 56km northeast of Posadas via RN 12. From the highway junction, Av Sarmiento leads 1km to the town center, where Rivadavia leads six blocks north to the ruins.
