The Río Iguazú in Misiones, Argentina offers distinctly different paddling experiences depending on which section of the river is accessed. The upper portion of the river provides calmer water suited to beginners and intermediate paddlers, while the lower portion downstream from the falls features rapids and swift currents that are more appropriate for experienced kayakers. Kayaking is not permitted within the boundaries of Parque Nacional Iguazú where the waterfalls are located, so paddlers must plan their routes accordingly and stay outside the park.

Guided kayaking tours depart daily from the puerto de Iguazú in Puerto Iguazú, with a typical route covering approximately 8 kilometers. These tours include life vests, paddles, and dry bags, and operators provide instruction on paddling technique and safety protocols before setting out. Routes make periodic stops along the banks for rest and photography. One notable destination accessible by water is the confluence of the Iguazú and Paraná rivers at the triple border point where Argentina, Brazil, and Paraguay meet.

The river runs through dense rainforest throughout its course in Misiones, and paddlers can expect to encounter diverse wildlife along the banks, including birds, butterflies, capybaras, toucans, and coatis. The surrounding jungle provides a consistent natural backdrop for the entire paddling experience.

For those interested in combining paddling with other activities, some operators offer combined kayak and paddleboard outings that also include short rainforest walks. The Paraná River, which the Iguazú joins near Puerto Iguazú, also offers additional paddling options in the broader region.
