Paraguari, Paraguay: Cordillera Hills, Ybycui National Park, and the Dia del Nino Battlefield

Paraguari is the capital of Paraguari department — a town of 28,000 at the gateway to the Cordillera de Paraguari, 65km southeast of Asuncion on Ruta 1, the most scenic department in the Asuncion-to-Encarnacion corridor. The Cordillera de Paraguari (the local name for the range of low hills rising abruptly from the flat Asuncion lowlands at the Paraguari town edge) creates a dramatically different landscape from the typical flat Paraguay of the lowland departments: the rocky cerros (hills) of Paraguari — Cerro Hu (Black Hill), Cerro Pelon, and the Ybycui hills to the south — are the most visually distinctive natural features in southern Paraguay. The Parque Nacional Ybycui (40km south of Paraguari, in the Ybycui hills) is Paraguay’s oldest national park (1973) and the primary protected subtropical forest in the region.

The Battle of Paraguari: War of the Triple Alliance (1869)

Paraguari has the distinction of being the site of one of the last significant military operations of the War of the Triple Alliance: the Battle of Acosta Nu (Campamento Acosta, 1869) — when a force of approximately 3,500 Paraguayan soldiers, predominantly children and elderly men in the final stage of the war (Paraguay’s adult male population had been largely eliminated), fought the Brazilian forces in the hills east of Paraguari. The battle — considered the most tragic episode of an already catastrophic war — is commemorated annually on August 16 as the Dia del Nino (Day of the Child) in Paraguay, a national holiday that honors the child soldiers who died at Acosta Nu. The battlefield site (15km east of Paraguari) has a memorial park with monuments and the documentation of the engagement that is among Paraguay’s most emotionally significant historical sites.

Cost of Living in Paraguari

Paraguari benefits from its position 65km from Asuncion — close enough for regular capital access (1 hour by bus, $2–4 each way, very frequent service) while maintaining the lower costs of a provincial town. The combination of low rent, good Ruta 1 transport links, and the scenic Cordillera landscape makes Paraguari one of the more attractive small-city bases in the Asuncion corridor for those wanting to live outside the capital.

Climate

Subtropical at 150m — similar to Asuncion but with the Cordillera hills providing slightly more air movement and marginally lower temperatures. Summer (October–March): 25–36°C. Winter (June–August): 10–22°C. The Ybycui forests in the national park maintain higher humidity and lower temperatures than the open agricultural land.

Things To Do

• Parque Nacional Ybycui — Paraguay’s oldest national park (40km south of Paraguari) protects 5,000 hectares of subtropical mixed forest — the transition zone between the subtropical Atlantic Forest and the drier interior forest types. The park has waterfalls (Salto Cristal — the most visited waterfall in Paraguay, a 9m cascade into a clear pool within the forest), hiking trails through the subtropical forest, and the historic La Rosada ironworks ruins (an 1850s iron foundry established by the Lopez government, destroyed during the Triple Alliance War, now a historic site within the park). Swimming in the park’s natural pools is the primary weekend activity for Asuncion families.
• Acosta Nu battlefield memorial — The Dia del Nino memorial site at Acosta Nu (15km east of Paraguari) documents the August 16, 1869 battle with interpretive panels, monuments to the child soldiers, and the recovered material culture from the battlefield excavations. The site is heavily visited on August 16 (national holiday) and on school field trips throughout the year — visiting outside these periods provides a quieter, more reflective experience of one of Paraguay’s most emotionally significant historic sites.
• Cordillera hills hiking — The rocky cerros around Paraguari — Cerro Hu (Black Hill, the most prominent) and the surrounding formations that rise abruptly from the flat plain — are accessible for hiking on the informal trails used by local families. The summit views across the flat Paraguayan lowlands to the north and the Ybycui forest hills to the south are among the best panoramic views accessible from a town close to Asuncion.

Getting There

From Asuncion: 65km southeast on Ruta 1, 1 hour. Frequent bus service from the Asuncion Terminal ($2–4, every 30–60 minutes on the Asuncion-Encarnacion Ruta 1 route). Paraguari is on the main Asuncion-Encarnacion highway — all Ruta 1 services stop here. From Encarnacion: 225km north on Ruta 1. For Parque Nacional Ybycui: the park entrance is 40km south of Paraguari via Ruta 1 and a secondary road — a vehicle is needed or a taxi from Paraguari ($10–20 round trip with waiting).

FAQ

Why does Paraguay celebrate Dia del Nino on August 16?

Paraguay’s Dia del Nino (Day of the Child, August 16) commemorates the Battle of Acosta Nu (August 16, 1869) — the engagement where Paraguay deployed its remaining military force, composed largely of children (boys as young as 9–12 years old, with fake beards attached to make them appear older) and elderly men, in a last defensive stand against the Brazilian army near Paraguari. Paraguay had lost approximately 60–70% of its total population in the War of the Triple Alliance by this point — the adult male population was essentially gone. The Brazilian forces were aware they were fighting children; the battle lasted several hours before the Paraguayan force was overwhelmed. The specific casualty count of child soldiers at Acosta Nu remains debated by historians (estimates range from several hundred to over a thousand), but the symbolic weight — children defending a country destroyed by a war not of their making — established the battle as Paraguay’s most emotionally powerful national memory. The holiday designation as Dia del Nino (not as a military holiday) reflects the Paraguayan choice to honor the children rather than the battle itself.
