Ireland: Coast and Country

Meeting a man on a mission to bring Ireland's native wildlife back to the forest, encounter wild dolphins underwater and witness rock climbers 70 and older who prove that age is just a number.

Ireland's only vermouth makers ply their trade; a goat herder is on an important mission; a centuries-old annual tradition known as "the Winterage" is celebrated; a helicopter operation hangs in the balance.

There's fine dining seafood from a food truck and the first native oysters of the season from a Michelin-starred chef; descending 50 meters below ground to explore the Marble Arch Caves.
