Argentine Side Tour – Approx. 5 to 6 Hours. The tour of the Argentinean side of Iguazú Falls takes approximately 4 to 5 hours and is divided into three main trails, each offering a unique perspective of this natural wonder. 1-The main highlight of the Argentine park is the spectacular Devil’s Throat. To reach it, visitors board the Ecological Jungle Train, which travels through the lush rainforest and along the river. You’ll disembark at Devil’s Throat Station, where a flat, accessible catwalk leads to viewing balconies right on the edge of the tallest and most powerful waterfalls. 2-This Upper trail offers panoramic views of several waterfalls from above, providing an impressive overview of the falls and surrounding river. 3-The Lower Circuit is a network of elevated walkways winding through the jungle, offering a more immersive experience. Along the way, you'll find several balconies and viewpoints that bring you closer to the base of the waterfalls.
