Monthly Update (August 2026):
Los Andes–Mendoza enters August after one of its longest winter closures of the year, with heavy snow keeping Paso Los Libertadores shut for much of the second half of July and leaving large numbers of trucks waiting on both sides. The closure was expected to extend into the first days of August, making this a particularly important crossing to check closely before traveling this month. Even after reopening, winter weather remains the main source of disruption on the route.
About this crossing
Operational Details
This checkpoint connects the Mendoza Province of Argentina with the Valparaíso Region of Chile. It is a massive, 24/7 international facility, but it is frequently subject to closure during the winter months (June to September) due to heavy snow and avalanches. The crossing is an integrated checkpoint, with both Argentine and Chilean officials housed in a single, large facility on the Chilean side at Los Libertadores. The pass is the main route for freight and passenger traffic between the two capitals, Santiago and Buenos Aires (via Mendoza), and it is notoriously congested, with queues for trucks and buses often lasting for many hours.
A History of Crossing the Andes
The history of this crossing is the history of the challenge of crossing the Andes. This was the route taken by the Army of the Andes, led by José de San Martín, in his epic 1817 campaign to liberate Chile from Spanish rule. The original pass was over the high Bermejo Pass, at an altitude of over 3,800 meters. To commemorate the peaceful resolution of a border dispute, the iconic Christ the Redeemer of the Andes statue was erected at the summit in 1904. In the 20th century, the Transandine Railway and later the Cristo Redentor road tunnel were built at a lower altitude to provide a more reliable, year-round connection. The old pass with the statue is still accessible in the summer months as a scenic detour.

Border Crossing Procedure
The border crossing procedure is a well-organized, integrated process. At the single checkpoint facility at Los Libertadores, you will proceed through a series of windows for both Argentine and Chilean immigration and customs. You will need a valid passport. Many nationalities can enter both countries visa-free for short stays, but it is essential to check the specific requirements for your nationality in advance. Vehicle registration and international insurance are also necessary. A key part of the process is the strict agricultural inspection by Chilean authorities (SAG), who prohibit the entry of most fresh fruits, vegetables, and animal products; declare all such items (fines high for non-declaration).
The Surrounding Region: Argentina Side
On the Argentine side, the crossing is the culmination of a spectacular journey through the Mendoza River valley. The road climbs steeply into the Andes, passing by the magnificent Aconcagua, the highest peak in the Americas. The area is a paradise for mountaineers and hikers. The nearby Puente del Inca is a unique natural rock bridge. The city of Mendoza is the heart of Argentina's most famous wine country, known for its Malbec wines. The region offers numerous opportunities for wine tasting, adventure sports, and enjoying the beautiful Andean scenery.
The Surrounding Region: Chile Side
On the Chilean side, the road descends from the tunnel via a famous and dramatic series of 29 hairpin turns known as "Los Caracoles" (The Snails). The scenery is breathtaking. The crossing is a gateway to the Aconcagua Valley, another of Chile's renowned wine regions. The nearby city of Los Andes is a major commercial center. The road provides a direct connection to the Chilean capital, Santiago, and the major port city of Valparaíso, a UNESCO World Heritage site.
