Picture a forest of palms tall enough to walk beneath, their gray columns rising twelve meters or more above a sea of grass, stretching to the horizon in every direction. That landscape once covered great swaths of Entre Ríos, Uruguay, and southern Brazil. Almost all of it is gone now, plowed under for crops and grazed away by cattle, until the towering yatay palm became a rarity in the very region it once defined. El Palmar National Park exists to hold the line. Within its boundaries survives one of the last extensive stands of these palms, a living window onto a world that the rest of the savanna has lost.
The yatay palm, Butia yatay, is the soul of this place. In the nineteenth century these palms blanketed the river country of the Argentine Mesopotamia and beyond, a defining feature of the landscape. Then came the slow erasure. As agriculture, ranching, and forestry intensified across the region, the palm savanna was cleared field by field, and grazing livestock devoured the seedlings before they could ever grow tall. The mature palms still standing today are old, many of them centuries old, survivors with no young to replace them across most of their former range. Argentina set aside this 85-square-kilometer reserve in 1966 precisely to break that cycle, giving the yatay a place to live and, crucially, to regenerate.
El Palmar is more than its palms. The park protects a temperate, humid savanna typical of the land between Argentina's great rivers, a mosaic of palm groves, open grassland, low woods, and gallery forest. Threading through it all are streams that run east to empty into the Río Uruguay along the park's edge. This variety of habitats supports a rich cast of wildlife. Woodpeckers hammer in the woodlands, foxes slip through the grass at dusk, and viscachas and capybaras, the largest rodent on Earth, graze near the water. The mix of palm, prairie, and riverbank makes the park a refuge for species that have lost ground elsewhere, and its wetlands are recognized internationally as a Ramsar site of conservation importance.
To visit El Palmar is to feel small in the best way. Trails and quiet roads lead through the groves, and a campground sits on the bank of the Uruguay River, where you can pitch a tent within sight of the slow water. At dawn and dusk the light slants low through the palm crowns and turns the grassland gold, and the silhouettes of the tallest yatay stand out like sentinels. The river marks the boundary between Argentina and Uruguay, so the far bank is another country. Set roughly midway between the towns of Colón and Concordia, the park is an easy detour from the river road, and a reminder of how much a single protected place can preserve when nearly everything around it has changed.
El Palmar National Park lies at about 31.85°S, 58.32°W on the west bank of the Río Uruguay in Entre Ríos, between the cities of Colón and Concordia. From the air, the river border with Uruguay is the key navigation reference, and the park's distinctive palm groves and stream channels stand out against the surrounding farmland. The nearest airport is Concordia's Comodoro Pierrestegui (ICAO: SAAC) to the north; across the river in Uruguay are Salto's Nueva Hespérides (ICAO: SUSO) and, farther south, Paysandú's Tydeo Larre Borges (ICAO: SUPU). A low-altitude pass at 2,500 to 4,000 feet best shows the texture of the palm savanna and the streams draining toward the river. Skies are typically clear in this humid subtropical region, with the best light early and late in the day.
