Caviana, River island in Marajo Archipelago, Brazil.
Caviana is a river island in the Marajó Archipelago that stretches across vast lowlands with forests and wetlands shaped by river and ocean tides. The landscape changes constantly as water levels rise and fall throughout the year in this region where the Amazon meets the sea.
The island formed over thousands of years from sediment deposits carried by the Amazon River, creating a substantial landmass at the river's mouth. This process continues today and keeps reshaping the island's form.
People here make their living through fishing and use traditional navigation methods that have been passed down through generations. This way of life is deeply tied to the rhythms of the river and the tides.
To reach this island you will need a boat from ports in Para state, as there is only limited accommodation and few services. Plan ahead since boat schedules and lodging options are quite restricted in this remote area.
Where the Amazon River meets the Atlantic Ocean near this island, standing waves called pororoca form when river and ocean waters collide powerfully. This rare natural phenomenon can be witnessed here under the right conditions.
