🇵🇾 Paraguay · Chaco and Pantanal
Tinfunqué National Park is one of the great protected areas of the Paraguayan Lower Chaco, in the department of Presidente Hayes. Unlike the dry Chaco of the north, here a wetland landscape dominates: marshes, floodplains, seasonal lagoons and extensive karanday palm groves, which flood in the rainy season and shrink in the dry one. It's a world of water and palms, of wide horizons and enormous richness of birds and aquatic wildlife, one of the most characteristic corners of the humid Chaco.
The park protects an ecosystem of great value for biodiversity: through its marshes and palm groves move marsh deer, capybaras, caimans, the aguará guazú (maned wolf) and an abundant birdlife, with herons, storks, ducks, southern screamers and numerous aquatic species that make the area a paradise for birdwatching. Its name, of indigenous root, evokes that land of waters and palm groves of the Lower Chaco.
This guide gathers the essentials of Tinfunqué National Park: its character as a Chaco wetland, its wildlife and birdlife, and the particular access conditions —it's a remote destination, with difficult roads and almost no services, subject to seasonal flooding. It's not a park set up for mass tourism, but a conservation area that rewards the prepared and respectful nature traveler, ready for a planned visit.
Tinfunqué National Park was created in 1966 to protect the wetlands, marshes and palm groves of the Paraguayan Lower Chaco, in the department of Presidente Hayes, and the rich wildlife associated with this environment of water and palms. It's one of the oldest protected areas in the country, with a name of indigenous root tied to this land of floodplains. The full history is on our history page.

Origins, formation and what the sources say.
There are places that defend themselves: to reach Tinfunqué you have to cross a river, venture into the Chaco on dirt roads that in summer turn into impassable mud, and trust that the water level lets you continue. That isolation, which today frustrates the hurried traveler, is exactly what turned this corner of marshes and palm groves into a wildlife refuge and a land of millennia-old peoples. Long before the park existed, the Lower Chaco region that Tinfunqué occupies today was —and remains— the ancestral territory of the peoples of the Enlhet-Enenlhet linguistic family (also called Maskoy). According to archaeological and ethnohistorical data, these peoples came to the Paraguayan Chaco from a sub-Andean zone of the northwest and advanced southeast, gradually populating extensive zones of the Central and Lower Chaco. In that process of migration and settlement, at least six subgroups differentiated, each with its own territory: the Sanapaná, Toba-Maskoy, Angaité, Guaná, Lengua-Norte and Lengua-Sur.
These peoples economically adapted to the environment of the Central and Lower Chaco —the same type of wetlands, marshes and palm groves that characterizes Tinfunqué— developing a deep knowledge of the territory, its water cycles and its wildlife. They maintained trade relations with their Nivaclé and Maká neighbors, while their main historical tensions were with the Chamacoco, the Ayoreo and the Toba-Guaicurú of other Chaco areas.
Today, the departments of Presidente Hayes and Boquerón concentrate the greatest density of indigenous population in Paraguay, with Enlhet, Enxet, Angaité, Sanapaná, Toba and Guaná communities that keep their language and culture alive. The name 'Tinfunqué', of indigenous root, is testimony of that millennia-old presence in the land of marshes and palm groves that the park protects today.
Tinfunqué National Park was created on May 4, 1966, by Decree No. 18,205, which makes it one of the oldest protected areas in Paraguay, within the country's first efforts to preserve its natural ecosystems. With 241,320 hectares, its objective was to safeguard the wetlands, marshes and palm groves of the Lower Chaco, in the department of Presidente Hayes, and the abundant wildlife associated with this environment of water and palms, so different from the dry Chaco of the north. The park also protects sites linked to the Chaco War (1932-1935) between Paraguay and Bolivia, which was fought largely on these lands.
The choice of this sector of the Lower Chaco responded to its ecological singularity: a mosaic of seasonal wetlands, lagoons and extensive karanday palm groves that, due to their biological productivity, sustains a rich community of birds and aquatic mammals. Protecting this zone meant conserving a representative sample of the humid Chaco, a key ecosystem of the Western region of the country.
Since its creation, the park has been part of the national protected-area system. In 2016, by Law No. 5874, Tinfunqué was recategorized: it ceased to be formally a 'National Park' to move to the management category of 'Managed Resources Reserve', a change that sought to adapt its legal status to the reality of the area and to international conservation standards, though in everyday use it's still called a national park. Its value lies both in the biodiversity it houses and in its character as a great wetland of the Lower Chaco, a type of landscape increasingly pressured by changes in land use across the Chaco region.
Tinfunqué is, above all, a wetland park. It belongs to the humid Chaco or Lower Chaco, the eastern strip of the great Chaco plain, closer to the Paraguay River and subject to seasonal flooding. Here, the summer rains transform the landscape into a vast system of marshes, wetlands and lagoons, while in the dry season the water shrinks and lays bare savannas and palm groves. This pulse of the water is the ecological engine of the region.
The most characteristic element of the landscape is the karanday palm grove, a palm typical of the humid Chaco that extends in dense formations over the floodable savannas. Alongside it, grasslands, woodland islets and bodies of water compose an environment of great richness, productivity and beauty, where life is organized around the seasonal availability of water.
This type of wetland is fundamental for numerous species and fulfills valuable ecological functions, like water regulation and the support of biodiversity. The conservation of areas like Tinfunqué is essential for maintaining a sample of these Lower Chaco landscapes, which in other parts of the region have been transformed by cattle ranching and agriculture.
The great treasure of Tinfunqué is its wildlife. The park's marshes and palm groves house emblematic species of the South American wetlands: the marsh deer, the largest deer of the subcontinent, strongly tied to these aquatic environments; the capybara, the largest rodent in the world; the caiman; and the maned wolf, a slender canid with long legs and reddish fur, a threatened species closely associated with the savannas and wetlands. To them is added a very rich aquatic birdlife.
This concentration of wildlife makes the park an area of great conservation value, especially in a regional context of habitat loss and transformation. Many of these species depend on the integrity of the wetlands and are affected when these are drained, fragmented or degraded by activities like intensive cattle ranching.
At the same time, the isolation and difficult accessibility of the park —precarious roads, seasonal flooding, absence of services— pose challenges for its management, control and for the development of orderly nature tourism. Tinfunqué thus remains more a refuge for wildlife and a conservation area than a conventional tourist destination: a space for valuing the richness of the Paraguayan humid Chaco and the need to protect it.
In recent decades, the department of Presidente Hayes has promoted an incipient tourist development based on rural and nature tourism, as a way of giving sustainable economic value to this remote territory without compromising its ecosystems. Ranches like Santa Carmen, Salazar, Santa Rosa or Iparoma, distributed along the Trans-Chaco Route, today offer lodging, traditional cuisine of the Western Region and nature-contact activities —horseback rides, canoeing, nighttime wildlife watching— that serve as an organized gateway to the world of marshes and palm groves that Tinfunqué represents.
This model, which combines the traditional cattle-ranching activity of the Lower Chaco with nature tourism, seeks to position the region as a reference destination inside and outside the country, taking advantage of nearby attractions like Laguna Salazar and the national park itself. Villa Hayes, just 31 km from Asunción across the Remanso bridge, consolidated itself as the gateway and services center of this whole area.
The challenge going forward is to ensure that this tourist development also benefits the Enlhet-Enenlhet indigenous communities who have inhabited the region since remote times, and that the promotion of the Lower Chaco as a destination doesn't lead to greater pressure on wetlands as fragile as those Tinfunqué protects. The park, with almost six decades of existence, remains the conservation anchor of a landscape that is, at once, natural and cultural heritage of Paraguay.
