Planning to spend most our days at the falls, we opted for the cheapest hostel. Big mistake. It was so disgusting. They had six dogs that covered everything from the sofa to breakfast in their hair!! The bathroom was cleaned once every three days, and as toilet paper couldn't be flushed, it stank!! The owners were also rude, Si lost his flipflops and found the owner walking about in them! Thankfully, our day trips to the waterfall were an awesome distraction. On our first day we made our way across the border to Brazil. The falls can be seen from both Argentina and Brazil, but friends recommended doing the Brazilian side first to get the full picture. From this side we could get a panoramic view of all the waterfalls from a distance and appreciate the size. In total, there was over 200 waterfalls in an area just over a mile and a half long. After paying the park fees, we hopped on a bus that led us to the start of the trail. Listening to the waterfall, we began to walk the short path which led us to numerous lookout points, often crowded with tourists. At our first stop we were greeted with the sight of a 500m length waterfall, emerging from the rain forest and cascading to the rocks below. Pretty spectacular, until you realise that there's another 1.5km of waterfall just around the corner! Iguazu Falls are the longest waterfalls in the world and are amazingly beautiful. The Brazilians have built a walkway that allows you to walk out onto the edge of the falls at a lower level, so that you have water dropping 350ft behind you and traveling under your feet before dropping to the rocks below. The falls were much bigger and more impressive than we imagined and we were both excited to see more. Early the next morning we caught a bus to the Argentina side of the falls where the longer trails led us to closer to the water. We appeared to beat the crowds and were only held up by a few large tourist groups. Despite it being really humid, clouds covered the blue skies! A tourist train took us into the park where we could walk the upper and lower trails. There were many wonderful viewpoints along the way. The views were breathtaking. One of my favourite views of the falls was from the island. Free boats take you across the water. At the top of the stairs you can see the power from the waterfall and the rainbow it creates. Perfect in colour and full in shape. You can also see the lighter waterfalls running next to the fresh green vegetation. It was incredibly stunning As we were walking towards the train to take us to another fall, my flip flop broke! After living in Fiji for a month I was used to walking barefoot, but the trails over the water were metal grates. I ended up fixing it with a plastic bag...Si was slightly embarrassed but I thought it was genius! We carried on to the last walk of the day. Although the all the falls are awesome, the crowning glory goes to the Devils Gorge. We walked along a boardwalk, passing turtles, butterflies and previous walkways destroyed by floods. As you round the corner the huge falls appear. They are beyond description!! The amount of water is immense. The sound is almost deafening. We stood and just watched the water gushing down spraying into a cloud of mist. The spray created another perfect complete rainbow! It was an epic day!
