Located on the Paraná River, this provincial capital in northeastern Argentina has year-round warm weather with temperatures around 21.5°C and connects to Brazil via an international bridge.
Posadas, the capital of Argentina's Misiones province, sits along the Paraná River across from Paraguay. Each evening, hundreds of locals gather at La Costanera promenade to share mate tea and watch the sunset over the river. The city serves as a gateway to the red sandstone Jesuit missions and the wildlife-rich Iberá Wetlands, where you can spot caimans, capybaras, and yellow anacondas in their natural habitat.
Getting to and Around Posadas
You can reach Posadas by air from Buenos Aires with a 90-minute flight to General José de San Martín Airport. Bus 28 connects the airport to the city center, taking about 40 minutes. Many travelers choose overnight buses from Buenos Aires, which take approximately 12 hours and depart from Retiro bus station. Within Posadas, public buses run every 15-20 minutes and the compact city center takes about 30 minutes to cross on foot.
La Costanera Waterfront
The 4-kilometer riverside promenade stretches through the city center, with views across to Encarnación, Paraguay. During summer evenings, when temperatures cool to around 25°C, you'll see families having picnics while children play in the designated playground areas. The promenade has 12 cafes and ice cream shops where you can watch cargo ships and fishing boats navigate the Paraná River.
San Ignacio Mini Ruins
This 17th-century Jesuit mission lies 60 kilometers from Posadas. The complex includes a church with 8-meter-high walls, living quarters, and a central plaza. The site spans 11 hectares, and guides explain the daily routines of the Guarani people who lived here. Look for intricate stone carvings combining European and indigenous designs in the doorways and walls.
Mate Culture
Groups gather throughout Posadas to share mate tea using a gourd and metal straw (bombilla). You'll see people carrying thermoses of hot water in parks, offices, and homes for continuous refills of this caffeine-rich drink. When summer temperatures rise above 30°C, many locals switch to tereré, a cold version mixed with ice and medicinal herbs like mint and lemongrass.
Wildlife and Nature
The Iberá Wetlands spread across 13,000 square kilometers of marshes, lakes, and grasslands. Take a boat tour to see broad-snouted caimans basking in the sun, marsh deer grazing by the water's edge, and hundreds of bird species. In Teyú Cuaré Provincial Park, 78 hectares of Atlantic Forest vegetation lead to red cliffs with viewpoints 40 meters above the Paraná River.
Local Markets
Plaza 9 de Julio hosts 30+ Guarani artisans selling woven textiles, mate gourds, and wooden carvings. On Saturdays, Fleming Street in the Bajada Vieja district becomes an open-air market with more than 50 local artists displaying paintings, ceramics, and handmade jewelry. Street murals by regional artists cover the walls of this 19th-century neighborhood.
