Arroyos y Esteros (Spanish for Streams and Swamps) is a district of the Cordillera Department, Paraguay.
Its name describes exactly the real aspect of this place, which is surrounded by swamps and streams. It was also named Tobatí Tuyá, which is one of the rivers of this region.
Its founder, Governor Pedro de Melo de Portugal called it "Chapel Duarte", but in 1849 Carlos Antonio López named it "Arroyos y Esteros".
Arroyos y Esteros is a small town, growing economically as well as in population. There are approximately 20,000 people living in the district, but these are found mostly in 13 outlying satellite communities, with only 8,000 inhabitants in the center of town. The topography can best be described in the words of the towns founder, Father Fidel Maíz, as having a lot of streams and swamps.
Once quite isolated, Arroyos now sits on the International Highway 3, which allows for rapid transit to Asuncion and the possibility of round trip travel in the same day. Historically Arroyos has close ties to the larger and more prosperous Tobati, approx. 23 km to the south.
