The Meeting of the Waters is the natural counterpart to the Teatro: the place every visitor to Manaus is taken at least once. Where the inky, slow-moving, warm Rio Negro joins the silty, faster, cooler Solimões, the two waters run parallel for kilometres in a clean dark-and-light line before eventually merging into what is properly the Amazon.
The standard way to see it is a half-day boat tour from the port, usually combined with stops at a floating restaurant for lunch, an igarapé walk on raised wooden boardwalks, and a brief visit to the giant Victoria amazonica water lilies. Bring a hat — the river glare is brutal.
