Belém can be an eye-opener for most visitors from the United States, who typically envision the Amazon as a vast, jungle-covered region with only a few primitive villages. Like Manaus to the north, Belém is a major city. It is also quite old — 2016 marks its quadricentennial. Though not in the state of Amazonas, it’s the gateway to the lower Amazon, and thus may be your embarkation or disembarkation port for a Brazilian Amazon cruise.
