Journey to Antarctica

Price: From $15,380
Duke Leaders: Dr. Nicolas Cassar

Remote. Untrammeled. Spectacular. Antarctica is one of the most exhilarating adventures on Earth. Every facet is thrilling and lovely. Its vastness is both humbling and uplifting, as is the ice in all its myriad forms. Relish the penguins—with their endlessly amusing antics, gabbling in their rookeries, bobbing by on a blue berg, or catapulting on to the shore.

See mountains rising some 9,000 feet up from the sea and an abundance of marine mammals. Hike and explore by Zodiac. Travel with an expedition leader and naturalists who have hundreds of journeys under their parkas.
