When the rains come, temporary lagoons fill, channels carve open, and the floodwater drains east and north toward the Pilcomayo River, which here marks the international border with Paraguay. The wetlands draw caimans, anacondas, and more than 300 species of birds, and the whole mosaic is recognized as a Ramsar site of global ecological importance. Argentina set it aside as a national park in 1951.

For birds, the park is a crossroads. More than a hundred species can be spotted across its grasslands and water, and some of them are creatures found nowhere in the northern world. Greater rheas, tall and flightless, stride the open plain like ostriches that took a wrong turn int...

Timing is everything in a place built on water. The climate is subtropical, warm and wet, averaging around 23°C with about 1,200 millimeters of rain a year, and winter, roughly June through August, is the dry season and the best time to come. The gateway is the town of Laguna Bla...
