The Paraguay River (Río Paraguay in Spanish, Rio Paraguai in Portuguese) is a major river in south central South America, running through Brazil, Bolivia, Paraguay and Argentina. It flows approximately 2,549 km from its headwaters in the Brazilian state of Mato Grosso to its confluence with the Parana River north of Corrientes. It divides Paraguay into two regions, the oriental and the occidental.
The Paraguay River was discovered by Alejo García in 1524. It has historically been of vital importance for transportation in South America, because it connects Argentina, Brazil, Bolivia, and Paraguay, as well as other countries throughout the Cuenca del Río de la Plata (Plata River Basin). In absence of roads and routes, the Paraguay River was the fastest and most efficient means of transportation and communication, giving Paraguay, a land-locked country, access to the Atlantic Ocean.
Today, it is not the main transit artery for travel in the area, but is still used for various purposes, especially for the transportation of bulk cargo (crops, minerals, fuel, etc.) and riverside people. Low water level is from March to October; this limits transit to boats of medium or low draft.
Crossing Paraguay, it has numerous tributaries, such as the rivers: Tebicuary, Ypané, Manduviré, Aquidabán, Apa, Confuso, Verde and Montelindo.
As it's a river, boats are really the only option. You can rent a private boat, take a cruise, or ride a cargo boat.
By fishing boatEdit
Fishermen and other locals are keen to offer their boats and canoes as water taxis for tourists. Just ask: even if he's busy, he'll know someone else who will be willing to take you.
- Boat Cuñatai. This boat travels short distances in the limits of Asunción.
By cargo boatEdit
The main long-distance river transport. These general-purpose boats take passengers as well as cargo, though they're not designed for passengers so there are generally no berths; if you're travelling overnight, you'll have to find a level surface to sleep on.
- Aquidabán Cargo Ferry – Goes between Concepción and Bahia Negra, 4 days upstream, 2.5 days downstream.

Not all boats (mostly only the ferries) are equipped with cabins. So, bring a hammock or camping mat with you.
Onward travel by boat leads to Brazil and Bolivia in the north, or Argentina in the south.
