Misiones is one of the 23 provinces of Argentina, located in the northeastern corner of the country in the Mesopotamiсa region. It is surrounded by Paraguay to the northwest, Brazil to the north, east and south, and Corrientes Province of Argentina to the southwest.
The province is embraced by three big rivers including the Paraná, Uruguay and Iguazú. Iguazu Falls are spectacular waterfalls on the Iguazú River in the northwest corner of the province, near the city of Puerto Iguazú. Misiones shares the falls with the Brazilian state of Paraná (in that nation's Southern Region). Meanwhile, the international border with Paraguay is close by.
