Discover the breathtaking waterfalls on the Argentine side of Iguazú Falls during this overnight tour from Puerto Iguazú. Arrive in in Puerto Iguazú to explore the charming little town and spend the night at a comfortable hotel. Head into the National Park in the morning with a local guide to see the majestic falls, including the massive Devil's Throat (Garganta del Diablo). Enjoy the best views of the falls with treks on both the Upper and Lower Circuits, then board the eco-train for a ride through the surrounding rainforest. Opt to upgrade your tour with a boat ride under the falls themselves that will leave you thrilled and soaking wet.
