Fishing near Eldorado, Misiones

Eldorado sits on the eastern bank of the Upper Paraná River in the center-northeast of Misiones province, and sport fishing — above all for golden dorado — is one of the area's defining recreational activities. The Paraná itself is the main draw, but a network of smaller arroyos including Arroyo Piray Guazú, Arroyo Piray Miní, and Arroyo Las Antas also sees local fishing pressure. The city's own Wikipedia entry lists sports fishing for golden dorado alongside sailing as a principal tourism activity.
