The Meeting of the Waters
Rio Negro at Sunset © P199
The Meeting of Waters is an incredible natural phenomenon occurring when the dark waters of the Rio Negro join the lighter-coloured stream of the Rio Solimoes. The difference between the blackwater and whitewater rivers is stark, running side by side for a length of more than four miles (6km) without mixing. The separation is caused by differences in temperature, density and flow, with the resultant display a true wonder of nature. Becoming a major tourist attraction in Brazil, the Meeting of Waters is accessed via an hour's boat journey from the floating docks in Manaus.
