Experience the largest waterfalls in the world by doing the catwalks that hang over the falls on both the Brazil side and Argentina side. You are guaranteed to get soaked! For more action, take the 15 minute boat ride that takes you under two falls twice for a total soaking. I stayed at the Iguassu Guest House where Carlos, the manager, arranged a easy way to cross the border to enjoy these falls from the Argentina side with four other travelers. It was a terrific cost and time savings over going by public transportation, especially by having a border "fixer" handle our immigrations. After returning to the hostel, we celebrated by heading to the nearby "Gaucho Churrascaria Restaurant" meat orgy.
I did my first blog on this trip and you check it out on this link. It describes in video, pictures and words this adventure.
