Iguazu Falls, some of the Jesuit missions in the Northern provinces (such as Misiones, appropraitely). San Ignacio Mini’s probably the most convenient one.
To the south and west, I liked the La Trochita narrow-gauge train and the scenery around Bariloche.
I hear there are so many, ahem, “German Immigrants” (who just happened to show up between 1945-47) there that many Argentines jokingly refer to it as “Bavarialoche”.
