The Paraná River sites in this part of northeastern Argentina are shallow, freshwater dives on artificial reef structures, with shore entry from towns including Paso de la Patria and San Cosme. Depths are modest, and the sites hold catfish, tilapia, and livebearers. Current is a defining factor: Boyas Blancas carries a strong, consistent flow that demands good buoyancy control, while Laguna Totora has no current and suits beginners looking for a calm environment. Visibility across all sites sits at roughly five metres, making this close-range diving focused on structure rather than distance. Night diving is available at Laguna Totora.
