The port and Costanera
Just beyond Avenida Roque Penez, Calle Fleming, more commonly known as the Bajada Vieja, is one of Posada’s most picturesque streets, lined with original nineteenth-century houses. The street leads down to the port, where boats formerly departed to Paraguay and Brazil, though the rising level of the Paraná has put all ferry services on hold for the immediate future. Nearby, at Roque Saenz Peña 1405, the Galería de Mate is worth browsing for its dizzying array of yerba as well as all the accompanying equipment, and other local handicrafts.
From here, the riverside walkway known as the Costanera is lined with bars and restaurants and is a lovely spot to watch the sunset or wonder about life in Encarnacíon, Paraguay, clearly visible on the opposite bank. Currently stretching about twenty blocks from north to east, it has been much improved in recent years, and is popular with joggers and dog-walkers; plans are in place to extend it as far as the international bridge.
