Crossing into Argentina
Transportation between Argentina and Chile is frequent and easy, with crossing the border a normal daily occurrence for locals, on par with a trip to the bank. The Chilean entry fee (US$117 for Australians) is valid for the life of the passport.
Do not cross the border where there are no officials to stamp you through or you will risk expulsion. The most-used border crossings are at Cancha Carrera, between Torres del Paine and El Calafate, and Monte Aymond, between Punta Arenas and Río Gallegos.
Flight service between Punta Arenas and the Argentine cities of El Calafate and Ushuaia began in 2017 and the reopening of the airport at Puerto Natales creates more options for travelers.
Frequent buses link Puerto Natales with the Argentine towns El Calafate and El Chaltén, and Punta Arenas with Ushuaia. If you travel from Ushuaia to Chile's Isla Navarino by boat, make sure to visit customs at the airport.
