The bus journey to Iguazu was by far the easiest 19 hrs on public transport I have ever had to endure. The bus was smooth, the seats large and lie flat, and the entertainment was not too intrusive. The food could have been better, but as it came with a couple of small bottles of wine and a half pint of Whiskey, it was edible (unless you're a veggie, in which case you where told by the bitter ponce of a steward that he had nothing for you), but lets not forget that we are talking about a bus here.
Foz De Iguazu, where we stayed, is on the Brazilian side of the Falls and with a population of 400,000 is the biggest one horse town in the world. We walked around in vain on the afternoon of our arrival, looking for a hint of civilisation. The closest we got was a Sushi restaurant where an English speaking, blond haired blue eyed Brazilian made sure we ate well. I enquired about his unusual colouring and discovered that his grandparents had emigrated from Germany at some point. Funnily enough, my enquiries as to why and when they came to Brazil were not answered! Our hotel in Foz was called the Charm Suites but lacked charm and the fact that the first 5 minutes in our room was spent trying to workout where we could put our bags is a indication that they where not suites either (my bag ended up under the sink in the bathroom. However it was cheap, the owner was very helpful and it had a much needed pool (aka a plastic bird bath sunk into the patio).
The Falls are incredible. We had a day each on the Brazilian side and the Argentinean side and found ourselves saying 'wow' with irritating frequently. They are the biggest falls in the world, but I am unsure by what measure. They are certainly expansive, powerful and utterly captivating. I don't know what it is about falls that can hold attention for so long but in the 10 or so hours we spent at them, we were never bored.
