+30Puerto Iguazú is a city in the Misiones Province of northeastern Argentina. It is situated at the confluence of the Iguazú and Paraná rivers, which also forms the tri-border area with Brazil and Paraguay. The city is internationally recognized primarily as the gateway to the UNESCO World Heritage site, Iguazú Falls, one of the world's largest and most spectacular waterfall systems.
The city was officially founded in 1901 during a period of territorial expansion. Its development was closely tied to its strategic port on the Paraná River and later to the tourism generated by the nearby falls. The urban layout and architecture are functional and modern, designed to accommodate the large influx of visitors. Its primary purpose is to serve as a tourist hub, providing services, accommodations, and access to the surrounding natural attractions.
Puerto Iguazú is accessible by air through Cataratas del Iguazú International Airport, which receives domestic and some international flights. It is connected by paved national routes to other major Argentine cities. The city has a bus terminal with services to locations throughout Argentina and to neighboring countries. The road infrastructure to the Iguazú Falls park is well-maintained. The city and the national park offer extensive tourist infrastructure, including hotels, visitor centers, marked trails, and viewing platforms. Access is generally year-round, though high water during the rainy season can affect some boat tours.
The region features a humid subtropical climate with abundant rainfall and high temperatures year-round. The landscape is dominated by the Atlantic Forest, one of the world's most diverse ecosystems, which surrounds the urban area. The area is rich in biodiversity, including coatis, toucans, and butterflies. The city is directly influenced by the powerful Iguazú and Paraná rivers. While the city itself is urbanized, it is immediately adjacent to highly preserved protected natural areas.
The area around Puerto Iguazú was originally inhabited by the Guarani people. European exploration began in the 16th century. The modern city's history began in the late 19th and early 20th centuries with the arrival of European settlers and missionaries, leading to its official founding in 1901. Its initial economy was based on forestry and yerba mate production. Its role transformed dramatically in the 20th century with the establishment of the Iguazú National Park in 1934, shifting its economic focus decisively toward tourism and cementing its status as an international destination.
