The largest and most visited of the islands, this green island was discovered by tourists in the 1980s. Lime Kilm Point State Park, on West Side Road, is home to the only park in the world specifically dedicated to whale watching. From February to June, as the waters warm up, Pacific grey whales travel up the west coast of the United States from the Mexican coast to the Arctic Ocean. At the end of the summer, they make the same journey in the opposite direction, reaching Washington State around October. Out of season, colonies of killer whales, now threatened with extinction, are easy to observe, spending most of the year in the salmon-rich waters of the Strait of Juan de Fuca.
