This is on the lower trail of the Iguazu Falls where you can get the most panoramic view on the Argentina side. These falls are extremely more impressive than the famous Niagara Falls and much less touristic as well (see comparison here). You can walk the lower trail to where you board the speed boat that takes you into the falls or the walkway that will take just under the falls (caution: drench warning!). You can see the Argentina side of the Iguazu Falls in one full day, it can be two half days as long as you have one full day. Truly one of the wonders of the world and is something that you should not miss on your trip to Argentina or South America. Take a peak at the video of the Iguazu Falls (click here).
