THE DETAILS

The next cruise season for Chile-based Australis ( australis.com) begins in September and runs until the beginning of April. The five-day “Fjords of Tierra del Fuego” itinerary described in this story navigates the Chilean coast between Punta Arenas and Ushuaia, Argentina, with rates from US$1,565 per person. Punta Arenas is four hours by plane from Santiago, a route plied multiple times a day by LATAM Airlines ( latam .com). Be sure to book a window seat, as the flight passes over the third largest ice cap in the world. Daily flights between Ushuaia and the Chilean capital on Aerolíneas Argentinas ( aerolineas.com.ar) are via Buenos Aires.
