Fishing the Agua Boa River offers the fly fisherman a trip that they will never forget. It is not just a fishing experience, casting a fly to strange and exotic fish in these pristine waters. They are, in our opinion, the fiercest freshwater fish you can catch on a fly-rod. Unlike most other Amazon fishing destinations, the beautifully clear waters of the Agua Boa, combined with the light sandy bottom, allow sight fishing to cruising Peacock Bass and Arowana. When the river has not dropped, anglers will spend less time in the main river channel and will instead focus upon the lagoons that are attached to the river and literally teeming with fish.
