Monday after classes and touring BA with my friends (and a scary allergic reaction to something in my salad which turned me totally BEAT RED, made my heart race, made me super hot and gave me a head ache and massive red rash on my stomach and legs) we boarded our supposed-to-be 18 hour bus to Iguazu falls (very Northern Argentina, on border to Brasil)and 23.5 hours later arrived there! We upgraded to the "cama suites" (cama=bed) which served great food, the beds reclined all the way, and they gave us 4 different kinds of booze! We had a great time and slept for most of the trip... although we were a bit disappointed to be arriving to late, so we checked into our hostel and just planned on seeing the falls the next day.
Up and at'em super early, we got on the 3rd bus from Puerto Iguazu to the national park where the falls are, and spent 3 hours in traffic and eventually turned back because there were protests at the opening to the park from workers who were demanding more pay... not sure where the workers were from, but it was quite the fiasco there that day and no one was able to go into the park all day. Unfortunately, there is nothing to do in Puerto Iguazu - and even the futbol match the guys were excited to watch wasn't coming through on the tv due to crappy cable, so most of the day was pretty much a wash. At one point we considered going to the Brasil side (literally like 2 miles away) but the visa office at the Brasilian consulate wasn't open, and I had heard mixed things about entering the country for the day just in the national park, so we didn't risk it and just had good food and siesta time for the day... planning to get up super early the next day to see the falls in the morning in time to catch my bus back to BA at 4pm.
The next day we woke up at 6am to be the first in the park and walked around for hours looking at all of the falls. It was incredible and truly breathtaking! there are some 300+ falls, and they are about 80 m high and about 2,700 meters in diameter, although they form a half-circle. The pictures don't do it justice, but there isn't much more to say.... other than check out the pics! They're on some list for being a natural wonder of the world, but they aren't one of the official "seven wonders of the world" although they are a World Heritage Site. After the falls I boarded my bus back to BA and although I wasn't in the "cama suite" I managed through the 19 hour bus ride back to BA ok.
Iguazu Falls (Argentina side)
23.5 hour bus trip there - they better serve free booze! :)
