Challenge. Desolation. Unlimited wonder. It’s not difficult to grasp what attracted the great explorers to Antarctica. Get a personal appreciation for the struggle to tame the bottom of the world on this 22-day adventure to the land than entranced Ernest Shackleton and countless others since. Down here, you’ll explore the Falkland Islands, encounter abandoned whaling stations on South Georgia Island, and pay your respects at Shackleton’s grave. Elsewhere, you’ll catch up with penguins (king, chinstrap, and gentoo varieties) and learn all about them through daily lectures, get close to whales and cavorting seals from a Zodiac boat, and keep an eye peeled for towering icebergs and massive glaciers. Prepare to be astonished.
