Fodor's Expert Review Meeting of the Waters
Outside Manaus, the slow-moving, muddy Amazon and the darker, quicker Rio Negro flow side by side for 6 km (4 miles) without mixing. If you run your foot in the water at the meeting place, you can feel the difference in temperature—the Amazon is warm and the Negro is cold, the consistencies of the rivers are different, and the experience is magical. The most comfortable way to experience this phenomenen is to book a day trip organized by a recommended tour operator, departing from Porto de Manaus. However, if you are short on time or want to skip the additional activities, head to the CEASA port, where you can rent a boat, or go with a tour company. It takes about an hour to go from CEASA to the Meeting of the Waters, spend some time there, and return. A taxi to CEASA from downtown is about R$30.
