Paso Cardenal Antonio Samoré is an international mountain pass at an elevation of 1.306m (4,284ft) above sea level, located on the border of Chile and Argentina. It is one of the main mountain passes through the southern Andes.
The pass links Osorno Province of Los Lagos Region in Chile with Patagonia, in Argentina.
The pass takes its name from Cardinal Antonio Samoré, who served as a mediator during the Beagle conflict between Chile and Argentina from 1978 to 1983.
Set high in the Andes mountain range, the road to the summit, formerly known as Paso Puyehue, is totally paved. It’s called Ruta 215 (in Chile) and Ruta Nacional 231 (in Argentina).
It’s one of the easiest of the Argentina-Chile passes, and one of the few with paved roads in the region. It is open all year round from 9am to 8pm, depending on winter weather conditions.
The pass is 102 km (63.37 miles) long running west-east from Entre Lagos (in Chile) to Villa La Angostura (in Argentina).
