Mark the precise 66°33' S latitude crossing with a traditional glass of champagne on deck, an old polar tradition few travelers ever get to do.
What to expect
The captain announces the countdown to the Circle over the PA, and passengers gather on deck bundled in parkas as crew pour sparkling wine. There's applause, photos with the GPS reading visible on a screen, and a genuine sense of having gone further south than most humans ever will. Icebergs and possibly whales often accompany the moment.
Good to know
