Crossing the Circle: Southern Expedition

Setting foot on the 7th Continent is a polar achievement relatively few people experience in their lifetime. Even more rare is the incomparable milestone that’s achieved when a traveler crosses the iconic Antarctic Circle. Navigating south of 66°33' S is-for most guests-the highlight of the 14-day itinerary Crossing the Circle: Southern Expedition, which rewards passengers daily with views of dramatic ice formations, humpback whales swimming alongside the ship, leopard seals diving beneath your Zodiac, penguins sliding off icebergs into crystal waters, or giant petrels soaring above the crackling sea. Starting in 2021, this itinerary allows you to the opportunity to experience our pioneering new vessel, Ultramarine. This purpose-built vessel is designed to extend the boundaries of polar exploration and offer an unmatched Antarctic experience, including a flightseeing tour you’ll never forget and a range of adventure options more extensive than any other ship in its class.

  • Be one of the few travelers to venture to 66°33'S
  • Visit Antarctic research stations
  • Witness abundant Antarctic wildlife, including penguins, seals and whales
  • Experience western Antarctic Peninsula highlights and visit iconic landing sites
  • Enjoy presentations on wildlife, history, glaciology & geology by our onboard polar experts
  • Immerse yourself in the icy realm of the Antarctic, with an optional paddling excursion
