Manaus is the capital of Amazonas State, located on the Negro River near its confluence with the Amazon. It is the chief port and a hub for the region's extensive river system. Once an extremely rich city due to its rubber plantation, today's Manaus is significantly poorer. Its economy is tied to the Amazon River and forest. It now serves as a major gateway to the Amazon, an important stop for travelers who want to experience the cruises or lodges of the Amazon.
