This 6 day cruise takes you to discover three kinds of Amazonian ecosystems – black, yellow and the rare ‘blue’ water rivers. The cruise starts in the city of Santarém, before cruising down the beautiful blue watered Tapajós river towards the National forest where a trek will take you to areas of primary forest and giant trees. The village of Alter do Chão, with its emerald green lake and a trek up to the Serra da Piroca will allow a panoramic view of the forest. From there, follow on to the majestic Arapiuns river, with its incredible beaches and interesting riverside communities before exploring the yellow waters of Amazon tributaries where fauna is more abundant and a chance to fish for piranhas and interact with a local community. The trip ends at a beautiful beach before returning to Santarém.
