Every year Chinook Salmon swim upriver from the Atlantic Ocean, crossing the whole Santa Cruz river and Lago Argentino (the biggest lake in Argentina) to arrive in Rio Caterina. The river is 8 miles long, fed by glaciers and smaller creeks that descent from the mountains and surrounded by the most spectacular scenery. The river is rather small, often not more than 20 meters wide, but has some deeper and wider sections. Fish can be encountered in the deeper pools as well as in more shallow sections where they are often visible to anglers, allowing for some entertaining sight fishing. This is especially true during the latter part of the season where huge fish can be seen fighting over territory in the shallow sections.
Wading is fairly simple and no deep wading is required.
