By river

There are 2500km (1563 miles) of navigable rivers in Paraguay and there are ferry links with Argentina Bolivia and Brazil. Travellers using the river to travel to Argentina should note that the Posadas (Argentina)–Encarnación (Paraguay) route is 321km (200 miles) shorter than the more traditional route to Buenos Aires. It traverses the Argentine provinces of Missiones and Corrientes and then proceeds across a new bridge over the Paraná River to Resistencia. Those who prefer to continue along the left bank of the Paraná River will have to travel to Paraná provincial capital of Entre Rios crossing under the Paraná River in the tunnel between the cities of Paraná and Santa Fé.
