Amazonas: Villages on the Rio Negro

Villages dot the shores of Rio Negro where descendants of indigenous Amazon tribes mix with Brazilians (there are still remote tribes deep in the Amazon that lead a primitive life but they are mostly off limits to tourists). The villages rely on fishing for most of their needs (electricity by generators is only a few outs a day, manioca is the only crop, and civilization is hours by boat). But fish is plentiful, jungle medicinal plants are abound, and mosquitoes don’t exist along Rio Negro as the water is too acidic for them to breed. There are schools and churches.
