Crossing from Mendoza to Chile: Routes and Travel Time

The Los Libertadores international pass is the main land route connecting Mendoza with Santiago de Chile. It is located 3,200 meters (10,500 feet) above sea level and is the busiest border crossing between both countries.

The total distance from the city of Mendoza to Santiago de Chile is approximately 360 kilometers. Although it seems like a short distance, mountain geography and immigration procedures can significantly alter travel times. That is why planning is essential to calculate your schedule accurately.

The step-by-step journey:

  • From Mendoza to the International Border (200 km): The trip begins by taking National Route 7 (RN 7) westbound. At km 120, you will pass through Uspallata (the last major town to refuel and stock up on supplies). At km 200, you will reach the Cristo Redentor International Tunnel, which marks the border between the two countries.

  • Customs and Immigration (Integrated System): If you are traveling from Mendoza to Chile, you do not complete any paperwork in Argentina. You must cross the tunnel and complete both processes (exiting Argentina and entering Chile) at the Los Libertadores Complex, located on the Chilean side. Conversely, when returning from Chile, you will do all the paperwork at the Argentine customs office in the Roque Carranza Complex (Horcones).

  • The Descent and Los Caracoles: Once you cross the tunnel and pass the Chilean customs complex, you will take Route CH-60. Here you will encounter the famous Cuesta de los Caracoles, a steep zigzag descent featuring 29 tight hairpin turns. This road requires maximum driving caution, especially in winter or on rainy days.

  • From Los Andes to Santiago (80 km): At the end of the mountain descent, you will arrive at the Chilean city of Los Andes. From there, the road to the capital becomes much faster. You must take Route 57 (Los Libertadores Highway) and drive the last 80 kilometers into Santiago.

  • From Los Andes to Valparaíso (130 km): If your final destination is the Pacific coast, you should not head down to Santiago upon reaching Los Andes. Instead, continue west along the same Route CH-60 (Los Andes Highway) and then merge onto Route 64 (or continue via Troncal Sur, depending on which part of the bay you are heading to). It is approximately 130 kilometers of fast highway that will take you straight to Valparaíso and Viña del Mar in an estimated 1.5 to 2 extra hours of travel.

How long is the drive from Mendoza to Chile?

The net driving time is between 5 and 6 hours, keeping in mind that mountain roads require lower speeds. On a normal day, customs procedures can take between 1 and 2 hours, bringing the total trip to about 7 or 8 hours.

However, during long weekends, holidays, peak summer shift changes, or when the pass reopens after a snowstorm, customs delays can add between 4 and 8 extra hours. During the high season, prepare for a trip that can extend up to 10 or 12 hours.

How do I know if the border crossing to Chile is open?

The Cristo Redentor border pass is usually open most of the year, but it can be temporarily closed due to heavy snowfall, bad weather, maintenance, or security operations. Therefore, it is crucial to check the pass status on official social media channels before planning your trip. The most reliable sources are Ruta Libertadores for the Chilean side, and Paso Cristo Redentor Mendoza for the Argentine side.

What do I need to travel to Chile from Argentina?

To cross the border into Chile, it is essential to comply with certain immigration and customs requirements. According to official information from ARCA (Customs Control Resources Administration, formerly AFIP), these are the main documents and procedures you need:

Chile - Argentina Customs: What can you bring across?

Chilean customs have strict controls on agricultural products, fresh food, alcoholic beverages and other goods. It is highly recommended to declare everything you carry to avoid fines or confiscation. You are not allowed to bring fruits, vegetables, meat, or dairy products without prior authorization. Additionally, there are limits on the amount of alcohol and tobacco for personal consumption.
