Paso de Jama, Mountain pass road junction in the Andes, Argentina.
Paso de Jama is a mountain pass and border crossing between Argentina and Chile in the Andes at approximately 4,200 meters elevation. The road connects both countries with a fully paved route across the mountains.
The pass opened officially in 1991 and received complete paving in 2005, establishing a permanent connection between the two countries. This development ended decades of reliance on poor mountain paths and alternative routes.
The pass follows ancient trade routes that indigenous communities have used for centuries to cross the Andes and connect peoples on both sides of the mountains.
Travelers should bring valid documents for border control and prepare for extreme temperature swings between day and night at this altitude. Warm clothing and plenty of water are essential, as conditions can change rapidly.
The highest point sits on the Chilean side at about 4,831 meters, making it one of the highest paved roads in South America. This elevation makes the pass a notable crossing point for continental traffic.
