Cruises visiting Antarctic Circle

Crossing 66°33′ S is a milestone few Antarctic travellers achieve — most itineraries turn back further north. Circle voyages push down the Peninsula's west coast through progressively wilder, icier waters where ships become scarce and the light turns otherworldly.

Expect a celebratory toast at the crossing, midnight-sun conditions in high summer, and a stretch of coastline — Crystal Sound, Marguerite Bay — that only a handful of expeditions see each season.
