From all sides now

Today was all about the waterfalls, which we've now seen from the air, from the water, from the Brazilian side and the Argentinian side. The helicopter view would have been terrific, had I not been sitting at the back in the middle with a column in front of me, a large man with an iPad on one side and a keen photographer on the other - if you do it, it's sauve qui peut: race for the front seat. Because these falls are so spectacular, you mustn't miss any of them. (Thank goodness for live view on my camera - it got a better view than I was able to.)

We drove back to the Argentinian side to walk right along the edge of the falls on a metal walkway with huge catfish lurking below and delicate butterflies floating above, and it was amazing to see so much water pouring and roaring over the drop. But it's not just spectacular: it's pretty too, with fresh green grasses growing on rocks in the river, flowering plants on the islands, and the butterflies. It helped, too, that after two days of cloud and rain, today was brilliantly sunny, with rainbows everywhere. (When it's a full moon, you can go out at night to see the falls under moonlight with moonbows.)

And then it was time to pack up again without really enjoying our lovely hotel with its inviting pool and wandering coati and pretty rooms and all, sigh. So tonight I'm in another fancy hotel, in Lima, and it's 1am here, which means 3am in Brazil, and I still have my homework to do, sorting out my afternoon activities for tomorrow. "Think about it overnight," suggested Johanna, without apparent irony.
