Car Rental Considerations
Crossing the border in a rental car between Chile and Argentina requires specific and often complex documentation, which must be arranged well in advance with the rental agency. Most major rental companies (e.g., Hertz, Avis, Europcar) offer this service, but it typically incurs an additional fee and requires extra processing time. You will need a 'Permiso de Salida del País' or similar international travel authorization document from the rental company, explicitly stating permission for the vehicle to cross into Argentina. This document certifies that the rental car can legally exit Chile and enter Argentina for a specified period. It is crucial to request this authorization at least 7-10 days before your pick-up date, as it often involves notarization and official stamps. Without this specific permit, you will be denied exit from Chile or entry into Argentina. Confirm all requirements and costs directly with your chosen rental agency before booking your car and planning your cross-border trip.
Road Conditions
The road approaching Paso Cardenal Samoré is fully paved on both the Chilean (Route 215) and Argentine (Ruta Nacional 231) sides, offering a smooth and scenic drive. From Osorno, Chile, you'll take Route 215 eastbound, passing through the beautiful Puyehue National Park, with a gradual ascent towards the border. On the Argentine side, Ruta Nacional 231 connects the border to Villa La Angostura, where it merges with the famous Ruta Nacional 40, leading south to Bariloche. Both routes are well-maintained. However, during the winter months (May-September), heavy snowfall and ice are common. Sections of the road, particularly at higher elevations, may require the use of snow chains, or the pass may be temporarily closed for safety reasons. Always check road conditions and border status before embarking on your journey, especially during winter.
