The Salish Sea

An Ecological Treasure of Global Significance, home to thousands of natural animal species, many of which are found nowhere else on Earth!

Internationally located in SW British Columbia and NW Washington State, the Salish Sea is the second largest inland sea along North America’s West Coast. Prior to 2008, the Salish Sea was commonly known, in a geopolitically divided way, as Puget Sound, the Strait of Georgia and Juan de Fuca Strait. Well-known cities along her shores include Vancouver and Victoria in British Columbia, and Seattle, Olympia and Bellingham in Washington State.
