Paso Futaleufú is an international mountain pass at an elevation of 335m (1,099 ft) above the sea level, located in the Andes, on the border between Chile and Argentina. It’s one of the lowest passes of the southern Andes.
To reach the summit, on the Chilean side, the road is called Ruta CH 231. It’s a good asphalted road. On the Argentinian side is Ruta 259. It’s gravel and dusty in summers. The immigration and aduana of either country is open in summer (8 a.m.-10 p.m.), and in winter (8 a.m.-8 p.m.). It’s the most commonly used border crossing from Argentina to the northern length of Chile’s Carretera Austral.
