Iguazu Falls stretches across the border of Argentina and Brazil, inside two protected areas:
- Iguazú National Park (Argentina) – Puerto Iguazú
- Iguaçu National Park (Brazil) – Foz do Iguaçu
Each side has its own entrance, trail network, transport system, and viewpoints. You cannot walk between them inside the park. You must exit and cross the international border by road.
