A short but spectacular ride from Bariloche to the foot of Cerro Tronador, the 3,478m thunderer on the Chile-Argentina border. Turquoise Lago Mascardi gives way to a narrow one-way gravel road that climbs to Pampa Linda and the Ventisquero Negro, where ice avalanches rumble off the glacier. Mind the timed one-way traffic schedule.
