We had two long driving days to get here but it really was worth it. The falls are absolutely amazing, much bigger than Niagra and the surrounding scenery is so lush. I was feeling particilarly brave this afternoon so i treated myself to a helicopter flight over the falls. You really can't apprechiate the scale from any photos, and walking around the falls getrs you close. but to follow the river down then just come over the top is breathtaking. Hoping to do a bit of rafting at the falls tomorrow then i'll be saying goodbye to sunny Brasil and heading off into the Argentinin Pampas.
