Can I rent a car in Argentina and return it in Chile while traveling in Patagonia?

Yes, you can rent a car in Argentina and return it in Chile, but it is a specialized service and not all car rental companies offer it. Major international rental companies like Hertz, Sixt, and Europcar sometimes provide this option, but availability can be limited and subject to high cross-border fees. It’s recommended to check with the rental company in advance and arrange the necessary documentation for crossing borders.
