Experience the legendary Cruce Andino, a spectacular bus and boat journey connecting Bariloche, Argentina, with Puerto Varas, Chile, through breathtaking Patagonian lakes and mountains. This iconic route offers unparalleled scenic beauty, making it a bucket-list item for travelers, but importantly, it is a passenger-only crossing, not suitable for private vehicles.
7 min readUpdated for 2025–2026 SeasonThe Paso Pérez Rosales, famously known as the Cruce Andino or Lake Crossing, is one of the most picturesque ways to traverse the Andes between Argentina and Chile. This multi-segment journey combines comfortable bus rides with serene boat trips across three pristine lakes: Nahuel Huapi, Frías, and Todos los Santos, all set against a backdrop of snow-capped volcanoes and lush forests. Dating back to the early 20th century, this route was initially a challenging mountain path and has evolved into a well-organized tourist excursion. Unlike traditional border crossings, it is designed exclusively for passengers, offering an immersive experience of the Patagonian landscape. Private vehicles cannot use this pass and must instead opt for alternative routes like Paso Cardenal Samoré. This guide focuses on the unique aspects of this incredible passenger-only journey.

Car Rental Considerations
It is crucial to understand that the Paso Pérez Rosales is a passenger-only route. You cannot take a rental car across this border.

It is imperative to arrange this documentation with your rental agency at least 2-4 weeks in advance, as last-minute requests are often denied. Some agencies may not permit cross-border travel at all, so always confirm policies directly with the rental provider.
