About 350 miles into the Amazon from Manaus you'll find the Rio Jauaperi. It is the most pristine area I've ever experienced. From pink river dolphins, to flocks of festive parrots, troops of red howler monkeys, tree boas, and so much more. The water is so clear, it's like a massive mirror making the line between water, sky and earth melt into each other in a magical setting. If you go to Brazil, getting this deep is the true Amazon experience. It's worth every second of travel to get there.
