Amazon jungle trips are more about the boating upriver into the damp, buzzing, oppressive ambience than seeing animals, since most of the bigger critters only appear at night when you least want to be there.
Floating about on a dugout canoe at night in search of caiman by torchlight, freaking at odd splashes and squawks and beating mozzies off would not be untypical
You may well see caiman (crocs), monkeys, sloths, pink dolphins, tarantulas, electric eels and parrots galore, but don’t think of this as a massed-animal experience such as you may see in East Africa or Namibia. Best July-Oct for the dry season.
Wildlife is possibly more visible in the Pantanal (see below) to the south, though it’s a swamp, not a jungle, so offers less ambience, romance or name-dropping.
Note that one of Brazil’s South America neighbours, Peru, also offers great Amazon experiences starting from the grubby town of Iquitos.
*Belem. A not unattractive Amazon city and starting point for Amazon river journeys. A riverboat up to Manaus takes about five days. Second-class on these boats is distinctly hot and uncomfortable.
If you can afford it tourist boats will not only give you a good night’s sleep and protect your valuables, but they may give you lessons on the environment too.
*Manaus. A historically interesting city, but now overbuilt and unattractive, though a necessary evil for starting Brazilian Amazon exploration.
***The Pantanal (way south of the Amazon). A massive wetland and ranch area in central-west Brazil (NW of Rio) alive with wild things, including iguanas, tapir, capybara, caiman (crocodiles), giant snakes and anteaters, but in particular birds (parrots, macaws and so on). It’s best July – Oct (the dry season, so less humidity, less mosquitoes, more life visible).
