A visit to the Argentinean side of Iguazu Falls is a completely different experience than the Brazilian and deserves a whole day's worth of your time. Walk along the man-made platforms and bridges that follow the contours of the river taking you right up next to hundreds of waterfalls covering a 4 kilometer stretch.
Iguazu falls were created approximately 200 thousand years ago by ageological fault where the Iguazu and Parana Rivers come together creating an 80-meter high cascade named "Garganta del Diablo" or Devil's Throat. The falls stretch over 3 kilometers wide making them taller than Niagara Falls in North America and wider than Victoria Falls in Africa. The average flow of water passing over the falls is 1500 cubic meters per second and depending on the water levels you can observe anywhere from 160 - 260 falls. The intensity of the fallsproduces a permanent fog, where sunbeams form multiple rainbows of incredible beauty.
Start off by walking down around the Circuito Inferior where several bridges take you right up next to the falls where you can stand and be soaked by the spray in seconds. Take the train to the "Devil's Throat" main falls where a man-made walkway leads you out over the river to experience the once-in-a-lifetime thrill of looking down into the Devil's Throat itself, a 90-meter-high cascade over which 13,000 cubic meters plunge per second.
Taking an optional boat trip (you may purchase this additional activity upon arrival), rafting or hiking in the park is another way to enjoy the day in nature and appreciate the falls from a different perspective. Don't forget to take your camera, rain gear and sunblock. Bring your own snacks and water to avoid paying high prices in the park.
If time allows on your way back to Puerto Iguazu, you may have a chance to stop at the 3 frontiers overlook point where you can see Paraguay, Argentina and Brazil at the convergence of the Iguazu and Parana Rivers. A blue, green and yellow obelisk represents the national colors of all 3 countries. This is also a great place to grab some last minute souvenirs from Iguazu Falls.
