Paddling near Castanhal, Pará

Castanhal sits in the northeastern Pará state, within the broader Amazon basin lowlands. The area is threaded by rivers and igarapés — narrow Amazonian waterways — that make for intimate flatwater paddling through dense riparian forest. The Rio Marapanim is the closest significant waterway, with the Rio Maracanã, Rio Capim, and a network of igarapés within reach for canoe and kayak exploration.
