About Ushuaia

Argentina's southernmost city sits between the Martial mountains and the Beagle Channel, where boats run to the lighthouse and sea-lion islands. Tierra del Fuego National Park and the End of the World train are short trips from town, and the port handles summer expeditions to Antarctica. December through February brings long daylight and the warmest conditions for hiking and channel cruises; outside that window, snow and short days change the itinerary.

Travel Tips

01End of World Logistics
Ushuaia is the gateway for Antarctica cruises - arrivals and sailings cluster on specific days. Book lodging early and allow buffer for flight weather delays.
02National Park Trails
Tierra del Fuego National Park trails are short but exposed to wind and rain - pack shells and warm layers year-round. Pay park entry and catch the End of the World Train only if it fits your schedule.
03Beagle Channel Tours
Boat tours to islands and sea lions run most days but cancel in rough seas - book flexible tickets. Mornings are often calmer; bring gloves even in summer.
04Windproof Packing
Wind is the defining element - prioritize windproof jackets over fashion layers. Waterproof footwear matters on muddy trailheads after rain or snowmelt.
