The Rio Javari is a major river in the state of Amazonas, Brazil. It is a tributary of the Amazon River, and paddlers typically access it by first traveling to the port in Tabatinga. From there, a motorized boat journey down the Rio Amazonas and up the Rio Javari is a common method of reaching paddling areas. One primary destination for paddlers is the Palmari Nature Reserve, located along the river. The paddling experience in this area is adventurous and focused on wildlife. Paddlers use canoes to navigate quiet creeks, both day and night, for close-up encounters with wildlife such as caimans. The overall character of the experience is one of remote jungle exploration, often combined with other activities like hiking. The river and its tributary creeks provide the main routes for these expeditions.
