At the village of Alter do Chão — where crystalline green water laps white-sand islands — embark on a guided kayak through the Arapiuns River's mirror-calm channels, stopping at a riverine community for açaí and local crafts.
What to expect
You launch from the famous Alter do Chão sandbar into water so clear you can see freshwater rays gliding beneath your hull. The Arapiuns channel narrows into cathedral-like forest tunnels where giant river otters fish and kingfishers arrow overhead. Your guide stops at a stilt-house community where local families share cold açaí pulp and demonstrate traditional net fishing. The paddle back through golden-hour light across the main river is the most photogenic moment of any Amazon cruise.
Good to know
Alter do Chão is reached by a short tender or water-taxi from Santarém port (approx. 35 minutes, USD 10 each way). Kayaking requires moderate fitness; single and tandem kayaks available. Pre-book with Voyagers Travel to guarantee your slot and guide. Carry cash in BRL for local purchases.
