Martin's travels take him 1,500 miles to the San Juan Islands in Washington State, just off America's North West Pacific coast, right on the border with Canada. From the San Juan Islands, Martin travels down America's West coast to visit the Channel Islands National Park, which is known as 'America's Galapagos' because of its unique wildlife. From the Channel Islands, Martin takes a 2,000-mile journey across the States to Louisiana, where he visits Avery Island and Delacroix Island.
