Hi - I've been reading many of the postings about the Falls (so very helpful!) I have my Brasil visa, (flying in and out of the Brasil side of the falls and planning on staying the night(s) on the Brasil side. Saw the note need a visa for Argentina - though when I checked out ARG website it said a visa not necessary for a stay of 90 days or less. True? Otherwise $160 for a day trip to see the ARG side of the falls - seems expensive, though if I'm coming all the way from the states, what's a bit more money?! Plan to be in the area early August. Will I need hiking boots, or would running shoes be okay or sturdy water shoes? Any thoughts on hotels to stay in on the Brasil side or would it be better to be on the ARG side?
Thanks for any and all help!
