Ushuaia is the capital of Argentina's Tierra del Fuego province and one of the southernmost cities in the world. It sits on the northern shore of the Beagle Channel, between the sea and the Martial Mountains, at 54.8° south. It has about 80,000 residents (2022 census) and was founded on October 12, 1884.
It is the base for exploring Tierra del Fuego National Park, sailing the Beagle Channel to the Les Eclaireurs lighthouse, seeing penguins on Martillo Island and, in winter, skiing at Cerro Castor. It is also the main gateway to Antarctica: over 90% of Antarctic tourism ships operate from its port, about 1,000 km from the Antarctic Peninsula.
The weather is cold all year, with average highs of about 12 °C (54 °F) in January and barely 2 °C (36 °F) in July. The best time to visit depends on what you want: October to March for hiking, boat trips and penguins; June to September for snow.
Boat trips leave from the tourist pier and visit Bird Island and Sea Lion Island, home to sea lion and cormorant colonies, on the way to Les Eclaireurs, known as the Lighthouse at the End of the World.
