Well, for me it has got to be the Amazon in all its majesty. The most curious natural sight I've seen here is the "Encontra das Águas" where the Rio Negro and Rio Solimões meet. The dark tea colored water of the Rio Negro do not mix with the much denser and turbid waters of the Rio Solimões. They create a wandering zig-zag path that goes on for miles. It really is a strange sight to see.

So what's the most exotic, most beautiful or most curious sight you've encountered here in Brazil? Tell us below:

(Guys, the beautiful Brazilian women don't count OK. We all know about them.)

The most curious would be a "Cartorio"

Most exotic "driving through the amazon rainforest and passing by a sloth thinking nothing of it"

The most beautiful is against forum rules ;)
