Cruising with Susan Calman

It's the second leg of the comedian's river cruise through Portugal's stunning Douro valley. Susan and a gang of new friends from the ship head out on a vineyard tour to the Quinta Sao Luiz - one of the oldest port houses in the country. There she sees a traditional - and surprising - way to crack open a bottle. After a quick tasting, she's off for a relaxing spa treatment in Lamego - and discovers that, in this part of the world, they even bath in the grapes.

In the first of a two-part trip, the comedian samples life in Buenos Aires, Argentina before embarking on an epic cruise to Antarctica, where she explores everything the region has to offer. Her state-of-the-art cruise ship is small enough to get close to nature without disturbing the wildlife, and there is plenty to see including whales, dolphins, seals, albatross, and 18 species of penguin.

The comedian concludes her epic trek to Antarctica, and the ship's onboard submersible gives Susan the chance to take in a very different view of the region. She is also given the chance to celebrate with the famous Antarctic Plunge, where guests jump off the back of the ship into the freezing waters for the ultimate wild swimming experience.
