Ushuaia: The Southern Gateway to Antarctica

Recognized as the world’s southernmost city, Ushuaia serves as the primary departure point for expeditions to the untouched frontiers of Antarctica. Between October and March — the austral summer — ships set sail from Ushuaia’s harbor, heading toward the Antarctic Peninsula. These voyages can range in length, typically lasting from around 10 days up to three weeks, with varying routes and highlights. Travelers can choose between expedition-style vessels, traditional cruise ships, or upscale luxury liners.

Each summer, thousands of adventurers journey to the White Continent, and Ushuaia — located just 1,000 kilometers from Antarctica — is home to the busiest embarkation port among the five globally used for Antarctic travel. Argentina has played a key role in Antarctic history since 1904, when it established a weather station and postal outpost on Laurie Island in the South Orkney Islands. This early base eventually became known as Orcadas Base. Argentina is also a consultative party to the Antarctic Treaty, signed in 1959, which promotes the peaceful use of the continent with a strong focus on scientific collaboration and environmental protection.

Tourism to Antarctica is regulated under the framework of this treaty to ensure minimal impact on its fragile ecosystem. As such, only a limited number of tourists are allowed to set foot on the continent at approved landing sites.
