The floodplains east and southeast of Santarém are among the Amazon's most rewarding excursions. Flooded for much of the year, the plains are home to fabulous birdlife (including toucans and macaws), pink dolphins, howler monkeys, sloths and anacondas. The sunrise and sunset views are pure magic and there's a real sense of tranquility out here. Take an overnight boat trip, go canoeing through the flooded forest and relax far from the tourist hordes. Gil Serique organizes especially enjoyable excursions here.
