Rainbow waves in 'big water'. Iguazu Falls at the border of Argentina and Brazil

Want to witness waterfalls so grand that they make Niagara look modest? Let's explore Iguazu Falls, the largest waterfall system in the world. The name 'Iguazu' comes from words in the regional languages Guarani or Tupi , which mean 'big water.' These series of waterfalls are formed by the Iguazu River, on the border between Argentina's Misiones province and Brazil's Paraná state. They feature a striking staircase formation, with a two-step cascade created by three layers of basalt.
