Over four months ago, we started our trip by visiting the amazing Angel Falls in Venezuela. Now, with just a couple of weeks before home time, we are once again visiting one of the world's most impressive waterfalls, the stunning Iguaçu Falls.

The waterfall forms part of the border between Brazil and Argentina, so has two perspectives, depending on whether it's seen from the Brazilian side or the Argentinian side. Brazil offers a higher, more panoramic overview of the falls, whereas Argentina gives a more "up close and personal" experience. We started with Brazil.

Our first sighting of the falls totally took our breath away - it was massive. 275 individual waterfalls crashing into a gorge 80m deep and over 3km wide, surrounded by lush rainforest as far as we could see. The sight was nothing short of spectacular. Our guidebook said "Iguaçu Falls are higher than Niagara, wider than Victoria and more beautiful than either". We didn't doubt it.

We continued down a walkway to get closer. The rainforest was teeming with life - we saw lots of colourful birds, dozens of different butterflies and scary looking stripy spiders. There were photo opportunities everywhere, with the impressive waterfalls making the perfect backdrop. At the bottom of the path, a boardwalk allowed us to get close to one of the bigger waterfalls by taking us out into the centre of the river. The waterfall was thundering in front of us and created a gail of wind and water, like standing out in storm. We got soaked!

The next day we were back at the falls but this time on the Argentinian side. The trails through the rainforest were much longer with more opportunities to see wildlife, including cheeky little racoons scrounging for food. There were more boardwalks too, allowing us to get much closer to the individual waterfalls than the previous day. We were able to peer over the top of some of the falls giving us an amazing perspective of the water crashing over the edge.

A train helps visitors get around the national park quicker, so we jumped on for a ride to Garganta do Diablo (Devil's Throat). A boardwalk led us far out into the centre of the massive river. On the way we saw a river turtle warming in the sun. As we walked further, the placid river suddenly turned into a furious monster with the water plunging 90m into a horseshoe shaped canyon. 13,000 tonnes of water per second were plunging into a misty abyss. We couldn't see the bottom because of all the spray. The power of the water was mesmerising. A huge rainbow shimmered in the sunlight - photos and videos would never do justice to this awesome sight. Anyone or anything unlucky enough to fall into the hole would be instantly crushed by the power of the water. As we stood in awe of the "Devil's Throat", the spray drenched us from head to toe. We were soaked again, but it was well worth it!
