Getting there & away
Buses from Alter do Chão to Santarém (R$2, 45 minutes) depart hourly from 6am to 7:20pm, except on Sunday, when service ends around 6pm. Catch the bus opposite Hotel Tia Marilda. There is no bus to the airport from Alter do Chão; if you’ve got plenty of time, you can take the bus as far as the airport turnoff, and wait for the shuttle from Santarém to pass, usually once an hour. Otherwise, a taxi to the airport (or to Santarém or the riverboat ports) costs a painful R$60 to R$70.
