You can access the Falls from both Argentina and Brazil, so on the first day we went to explore the Argentinean side. When you first get into the national park it's a fair walk to the falls themselves so we took a little train part of the way. Once you leave the train you walk about 1km across bridges to reach the Devil's Throat for the first spectacular view. As you walk towards it you are crossing the river the whole time, but it's really flowing quite calmly and you get no impression of what's about to come. Once you reach the 'throat' though the sheer power of the water is overwhelming. You just stand there in awe of this amazing natural phenomenon watching gallons of water plunge over the edge into the abyss below, so deep you can't see the bottom because it's obscured by so must mist from the power of the water.

As you walk along the specially created platforms to see more of the 'throat' every now and again the mist clears, long enough for you to take some quick snaps and then to see the people on the other side - viewing the Falls from Brazil. There were so many people here, but somehow this time it didn't matter, as it was just amazing. So much to look at you hardly noticed everyone else.Then it was time for some proper exploring as we walked around the upper circuit. This allows you to get really close up to the Falls and peer over the edge - behind the safety of barriers though. There's no danger of anyone falling over…no not even me and my clumsiness came close!

The Iguassu Falls themselves are a huge series of many different waterfalls covering quite a wide area. Rather than being the widest or the deepest the beauty and attraction is in the sheer number of different waterfalls and how wherever you stand the view just seems to get better and better. Plus with the power of the water and the constant sunshine there is always a rainbow in view, which makes for fantastic pictures.

In the afternoon we took a 4x4 ride through the rainforest to a different part of the Falls. We had a very strange guide who was giving the commentary in both Spanish and English, although the English version was considerably shorter than the Spanish one - Spanish lessons coming in well again! Then it was time for the fun part of the day as we prepared ourselves for a jet boat ride up the river to the Falls. We had been warned about how wet you get and advised to wear bikinis…so all kitted out in our swimming gear we got on the boat…only to find that everyone else was just sat there fully clothed. We looked ridiculous and it was absolutely freezing…but we got the last laugh. When we got to the Falls the driver took us right up and under the waterfalls. It was incredible to get that close and literally feel the pounding of the water. It was so loud you couldn't hear each other talk and getting so close we did get absolutely soaked. So when we got off we all had dry clothes to put on where as everyone else had to wander around in their wet stuff!

Before we left we had enough time to walk the lower circuit too. Yet more pictures and more rainbows. It is an absolutely amazing place and no amount of writing about it can ever really do it justice. It's all about the pictures…of which I have many!

So the next day it was over to the Brazilian side. Where as the Argentinean side gives you the close up view, the Brazilian side gives you a better overview. I started the day by taking a helicopter ride over the entire Falls. It was a beautiful way to see the whole area and get a better perspective of the layout. Afterwards we then walked the length of the Brazilian side, each corner giving another wonderful view and opportunity for yet more pictures. When you got to the furthest point there was another chance to get up close and personal…and wet…and you walked along the platforms under the Falls. There were a lot less people on the Brazilian side, which made it easier to get those perfect picture moments. But if I had to choose which side I thought was best I really would struggle. Both have their advantages and it's worth spending at least two days here so you get the chance to appreciate both sides.

After an exhausting couple of days I then had plenty of time to rest as we took the overnight bus to Sao Paulo.
