This lovely hill town, set in a green valley with fabulous vistas of the surrounding mountains, is where Tucumán folk traditionally head to take refuge from the summer heat. It's no wonder. Tafí makes a fine spot to hang out for a few days; it offers crisp mountain air, hiking options, budget accommodations, memorable estancias, and a laid-back scene.
The journey from Tucumán is spectacular: a narrow river gorge with dense subtropical forest on all sides opens onto the reservoir-filled valley beneath the snowy peaks of the Sierra del Aconquija. The precipitous mountain road merits a window seat.
