Antarctica21 Expeditions

Transform your perspective on the planet and your relationship to it. Antarctica21 is committed to creating the ideal Antarctic expedition, providing safe, convenient, comfortable access to a life-changing experience.

Expeditions in Antarctica

Antarctica21 pioneered air-cruise expeditions in Antarctica, and we understand all the complexities of ensuring a smooth, safe, and enjoyable adventure. Our team knows the region’s unique geography, natural history, wildlife, and ecology. Above all, we love sharing our expertise with our travelers.

Moreover, this is our backyard. Our company was founded in Punta Arenas, the traditional gateway for the first Antarctic explorers. It remains an ideal base of operations as we respond to our region’s changing conditions, constantly refining and enhancing our trips.

Thanks to our Antarctica21 team and their service, we offer the most extensive suite of Antarctic air-cruises in the world. We are proud of this achievement, and we continue to improve our service and our expeditions. As the leading boutique tour operator of expeditions in Antarctica, we constantly strive to innovate and develop our environmentally responsible expeditions to the White Continent.

Our small expedition vessels are more like private yachts, offering direct access to areas along the Antarctic shore that larger ships simply can’t reach.

With fewer guests, you get on and off faster, so time ashore is focused where it should be: savoring every moment of a travel experience unlike any other.
