Facing the Atlantic

The journey begins in the Azores, an archipelago of nine islands pushed up from the sea by volcanic eruption. The islands belong to Portugal and are a third of the way across the Atlantic to America.

The journey continues over the Pyrenees to France. Orlu National Park is a rich upland area south of Toulouse and home to the largest squirrel in the world - the marmot.

The journey has reached Ireland and its ancient woodlands. There's also the amazing sight of 30,000 pairs of gannets on Skellig Islands, and below the nesting gannets and the stunning cliffs is a hidden wealth of sea life again fuelled by the Gulf Stream.
