Paso Los Libertadores (Cristo Redentor) Border Crossing
Connecting Santiago with Mendoza, Paso Los Libertadores, also known as Cristo Redentor, is the busiest and most iconic border crossing between Chile and Argentina. Traversing the high Andes through a 3,200-meter tunnel, it offers breathtaking views but is frequently subject to closures in winter due to heavy snow and notorious for long queues during summer peak season. Prepare for a grand adventure through the mountains.
Paso Los Libertadores (Cristo Redentor) is the principal land link between Chile's bustling capital, Santiago, and Argentina's renowned wine region of Mendoza. This high-altitude crossing, featuring the famous 'Caracoles' (switchbacks) on the Chilean side and an impressive international tunnel, is a vital artery for both commercial traffic and intrepid travelers driving through Patagonia or simply connecting these two major cities. While its scenic beauty is unparalleled, its operational status is heavily influenced by Andean weather, making meticulous planning essential, especially during winter months when closures are common. For those venturing south from central Chile or north from Argentina, this pass serves as a key gateway, demanding preparation for varying conditions and potential delays.
Location
Nestled high in the Andes Mountains, Paso Los Libertadores is an international mountain pass on the border between Chile and Argentina. The border post itself is located near the eastern entrance of the Cristo Redentor tunnel, at an elevation of approximately 3,200 meters (10,500 feet) above sea level. It's a crucial route through a dramatic and often challenging alpine landscape.

Hours of Operation
Summer
24 hours (typically from October to April), though subject to weather conditions and traffic volume.
Winter
8:00 AM to 8:00 PM (typically from May to September), with frequent partial or full closures due to heavy snow, ice, or rockfalls. Hours can be reduced further without notice.
Notes
Always check the current status with official Chilean (Carabineros de Chile) or Argentine (Gendarmería Nacional Argentina) sources before departure, especially during winter or volatile weather periods. Websites like Vialidad Chile or specific border crossing status pages are highly recommended.
Requirements
Required Documents
- Valid passport (and visa if required for your nationality)
- Migration Form (PDI form for Chile exit, Argentine entry form if applicable)
- International Driving Permit (IDP) - highly recommended for non-Mercosur citizens
- Copy of flight or travel itinerary (less common for land borders but good to have)
Vehicle Documents
- Vehicle registration document (Padrón or Título del Automotor)
- Proof of ownership (if not owner, a notarized power of attorney from the owner)

- Valid driver's license from your home country
Insurance
Mandatory Mercosur-specific vehicle insurance (Seguro Obligatorio Automotor or SOA, often referred to as 'Carta Verde' or Green Card). Ensure your policy explicitly covers international travel between Chile and Argentina. Rental agencies typically arrange this for an additional fee.
Customs
Strict regulations apply to agricultural products, fresh fruits, vegetables, meat, and dairy products to prevent the spread of diseases. Declare all goods. Failure to declare can result in confiscation and fines. Personal luggage is generally not extensively scrutinized unless suspicion arises.

- 3Present your passport, migration forms, and answer any questions from immigration officials.
- 4Once immigration is complete, proceed to the vehicle inspection area. All occupants must exit the vehicle with all luggage.
- 5Present your vehicle documents and rental car authorization to customs officials. Your vehicle and luggage will be inspected for prohibited items (especially agricultural goods).
- 6Receive stamps and approval for both yourself and your vehicle. Officials will provide a temporary import permit for your vehicle into Argentina.
- 7Return to your vehicle and drive through the Cristo Redentor tunnel.
- 8Upon exiting the tunnel on the Argentine side, you will occasionally encounter an additional Gendarmería (Argentine border patrol) checkpoint, where they may briefly verify your documents before you continue your journey towards Mendoza.
Estimated Time: During off-peak times (early mornings, weekdays in shoulder season), the process can take 1-2 hours. In peak season (December-February, public holidays, weekends), wait times can easily extend to 4-8 hours, or even longer depending on traffic volume and staffing.
Tips
- Arrive as early as possible in the morning to beat the queues, especially during summer months.
- Have all your documents neatly organized and readily accessible to expedite the process.
- Avoid crossing on Friday afternoons, Sundays, or public holidays if possible, as these are typically the busiest times.
- Pack snacks and water, as there are limited facilities and long waits are common.
- Ensure your rental car authorization is clearly visible and understood by officials.
Wait Times
Peak Season
Expect significant delays, often 4-8 hours, particularly during December-February, Easter, and long weekends. Queues of several kilometers are not uncommon.
Off-Season
Generally shorter, ranging from 1 to 3 hours. However, weather-related closures or reduced staffing can still cause unexpected delays.
Best Time to Cross
Early weekday mornings (before 8 AM) during the shoulder or off-season (e.g., May, June, September, October) are typically the quickest times to cross.
Car Rental Considerations
Crossing international borders with a rental car, especially from Chile to Argentina via Paso Los Libertadores, requires specific authorization and is subject to strict rules. Most rental car agencies in Chile *prohibit* taking their vehicles across the border to Argentina due to the associated logistical complexities, insurance requirements, and higher risks. For the few agencies that do allow it, you will need to: 1) Notify them well in advance (often 7-10 days) that you intend to cross. 2) Pay a significant cross-border fee (this covers the necessary Mercosur insurance and the 'permiso de salida' or authorization letter). 3) Ensure you receive the official, notarized 'permiso de salida del país' document from the rental company, which explicitly states the vehicle is allowed to leave Chile and enter Argentina. Without this document, you will be denied exit at the Chilean border. Always confirm these details directly with your chosen rental company before booking.
Road Conditions
From the Chilean side, the approach is via Ruta 60. This road is famous for 'Los Caracoles,' a spectacular series of 29 switchbacks that climb dramatically towards the tunnel entrance. While entirely paved and generally well-maintained, the ascent can be challenging, especially for larger vehicles. In winter, chains are mandatory and frequently required, and the road can be closed for days due to heavy snowfall. From the Argentine side, the approach is via Ruta 7, which is also fully paved and generally a gentler, though still high-altitude, climb through the Aconcagua Provincial Park region. Both sides offer stunning mountain views but can be prone to rockfalls and ice in colder months. Always drive cautiously and be prepared for sudden weather changes.
