Considered by many as the gateway to the Amazon Rainforest, Manaus sits on the Negro River. The capital of Amazonas and one of the largest cities in the country it has incredible landmarks like the Rio Negro Palace and the Amazonas Opera House. If you’re in the mood for some phenomenal nature, check out the Meeting of the Waters, a three mile stretch where the Solimões and the Negro Rivers run side by side without fully mixing. Eventually, both rivers converge to form the Amazon. Most people come here as a stopping point on their way into, or out of, the Amazon. If you’ve got time, check out the zoo that lets many of the animals roam free, and a little beachside museum just outside the city centre.
