Bañado La Estrella, Vast wetland system in Formosa Province, Argentina.
Bañado La Estrella is a vast wetland system in Formosa Province with lagoons, marshes, palm groves, and flooded forests where vine-covered dead trees dot the landscape. The Pilcomayo River shapes the terrain, creating a complex network of water and vegetation.
The wetland formed through natural processes shaped by periodic flooding from the Pilcomayo River over thousands of years. Water management structures were built in 2012 to improve access and help regulate seasonal flooding patterns.
Indigenous groups including Pilagá, Wichí, Qom, and Nivaclé communities maintain their languages and traditions throughout the region, shaping how people interact with this landscape. Their presence reflects a long connection to the river and wetlands that defines local life.
Access is mainly through El Vertedero, about 45 kilometers from Las Lomitas, or Fortín La Soledad at roughly 65 kilometers via provincial route 32. The dry season offers the best conditions for visiting when water levels drop and trails become more passable.
The area hosts over 300 bird species, from raptors to waterbirds, that can be regularly spotted throughout the landscape. Large mammals like the aguara-guazú fox and giant otters make their home in these waters and forests.
