Following your Iguazu Falls adventure, you will fly back to Buenos Aires and transfer to your NCL designated hotel. Guests who depart from Buenos Aires on the day of the tour cannot participate as they will not make it on time to connect with any international fight. This is an overnight tour and hotel is not included. Fly to a national park on the border of Argentina and Brazil and behold the staggering power and beauty of Iguazú Falls by walking along trails and cat walks that give you extraordinary views of this amazing natural wonder. After departing from the pier, you will transfer to the airport in Buenos Aires and fly directly to Iguazu, which lies inland near Iguazú National Park. The falls were discovered in 1541 by Alvar Nunez Cabeza de Vaca and established in 1984 as a Natural World Heritage Site by UNESCO. Situated in Iguazú National Park, the falls are shared by both Brazil and Argentina. The massive cascade is made up of 275 separate waterfalls that thunder down sheer cliffs in a majestic display of nature's power. The falls are nearly twice as high and three times as wide as Niagara Falls, a fact not lost on Eleanor Roosevelt who reportedly said, "Poor Niagara," when she beheld roaring Iguazu. You will observe this staggeringly beautiful, natural phenomenon by walking a path either above or below the falls. Both trails are extraordinary in their own way. The surrounding rainforest is equally impressive, as it is home to about 2,000 plant species and 400 bird species, including toucans, parrots and peregrine falcons.
