IGUAZU FALLS, ARGENTINA AND IGUACU, BRAZIL

My first long-dist bus journey in Argentina. About 20 hrs from B.A to Puerto Iguazu. Took "cama" which is a seat that is almost like a bed when fully reclined. Plus the "Singer" service provided a blanket and refreshment. being a fri the bus was full. We made several stops along the way. In the morning I jumped out and got my luggage - only to be told we weren´t there yet! Good thing I wasn't left behind at Dorada. I found a good hostel about 2 blocks from the bus terminal, Hostel Iguazu Falls (part of hostel international). After checking in and having a shower, i went in search of a much-needed meal. After that I thought I would have a siesta and spend a full day at the falls the next day when i would be feeling invigorated.
On Sun I caught a local bus to the Falls,in Argentina, about 30 min from town. We passed lots of smart hotels and were not far from the airport.
You have to pay an entrance into the national Park. From nearby you catch a small train that takes you to the walkways to view the falls. I started with "The Upper Circuit" - a steel walkway takes you to the edge of the Falls and you look at them cascading from beneath you - utterly incredible and breathtaking! One view after another unfolds as you walk along the path. Rainwater and spray come down on you - it helped to purchase a poncho. Every now and then the sun came out and there were rainbows over the falls. I could not get enough! Then on I went to "The Lower Circuit" which I loved even more. You get even closer to the falls and you see them pouring down towards you. Even more spray! I watched the boats below going up past San Martin Island and heading into the swirling water below the falls; they also go below the Devil's Throat. The boats look so tiny. I couldn't wait to do it myself - had already bought my ticket. I walked down the steep rocky path (signs: no pregnant women/no heart problems) and came onto the path just above the level of the water. Before getting on the boat, I was given a lifejacket (not that it would have helped I don't think) and a dry bag for my backpack, camera etc.. Once on the boat we moved slowly towards the falls, in awe of their force. Then - a warning that we were going to get wet - and in we went! Cool sharp water came cascading down on us. So much so that I lost my contact lenses and my vision was a blur ( or thought I'd lost them - they'd floated up). Then we came out for a breather and went back in. It was so exhilarating and intense. And suddenly over - 30 min felt like 5.
Fortunately the sun came out enough for me to dry off.
Later in the aftrenoon I got the train to "The Devil's Throat Circuit". On the way you walk over the upper river and see rocky islands. The catwalk takes you to a horse-shoe where the waters are boiling and foaming and sending up clouds of spray: the waters of the Devil's Throat go pouring down below. Cold and tired i had a hot chocolate before going back to the hostel.
On Monday I caught a bus to the Falls, in Brazil (yes, Brazil for a day!). We exited Argentina passport control and entered Brazil without any problems. After paying to go into the Brazilian National Park, you get on a bus that takes you to the trail from where you can view the falls. The advantage of the brazilian side is that it gives you a panoramic view of the falls (now on the opposite side). This time a catwalk takes you to the bottom of The devil's Throat where you can get wet (or not). You can also go up in elevators with glass sides giving you a spectacular view of the falls. Viewing the falls is so addictive. Eventually I tore myself away and got the last bus home at 5 p.m
