Río Los Antiguos is a stream flowing through the Santa Cruz province of Argentine Patagonia, draining into the broader watershed near the town of Los Antiguos along the shores of Lago Buenos Aires. Set against the dramatic Patagonian steppe and Andean foothills, this river offers a diverse angling experience in one of South America's most scenic and remote fishing regions. The river is known for its populations of brown trout, perch, and pejerrey (silverside/atherine), making it a worthwhile destination for anglers exploring the Santa Cruz interior.
