Iguazu Falls spans the border of Argentina and Brazil

Iguazu Falls is a massive system of approximately 275 individual waterfalls located on the border between Argentina and Brazil within the Atlantic Rainforest. The falls follow a prominent basalt step where the Iguazu River transitions into the Paraná River valley.

A central feature of the system is the Devil’s Throat, a massive horseshoe-shaped waterfall reaching heights of approximately 260 to 270 feet. The falls stretch for nearly 2 miles (2.7 km) along a wide canyon.

The area is protected by national parks on both sides of the border: Parque Nacional Iguazú in the Argentine province of Misiones and Iguaçu National Park in the Brazilian state of Paraná. These protected regions encompass tens of thousands of hectares of subtropical rainforest and are recognized by UNESCO.
