Martin Clunes embarks on an epic 10,000 mile journey around the coast of America, from Hawaii, Alaska and New England to Puerto Rico and San Juan.
In this episode, Martin travels to two dramatically contrasting landscapes: the lush, tropical Hawaii islands and the snow-fringed glaciers of Alaska's islands.
Martin's travels take him to the San Juan Islands in Washington State, the Channel Islands National Park - known as 'America's Galapagos' - and Avery Island in the Gulf of Mexico.

Martin arrives in New York for the final leg of his journey to explore Manhattan Island, and its world famous Empire State Building, and nearby Ellis Island. (Final)
