Deception Pass is a strait separating Whidbey Island from Fidalgo Island, in the northwest part of the U.S. state of Washington. It connects Skagit Bay, part of Puget Sound, with the Strait of Juan de Fuca.
Upon completion in July 1935, the 976 foot span Deception Pass Bridge connected Whidbey Island to the tiny Pass Island, and Pass Island to Fidalgo Island. Prior to the bridge, travellers and businessmen would use an inter-island ferry to commute between Fidalgo and Whidbey islands.
Deception Pass is today surrounded by Deception Pass State Park, the most-visited park in Washington with over 2 million visitors each year. The park was established in the 1930s when the Civilian Conservation Corps (CCC) built roads, trails, and buildings in order to develop the park. Deception Pass is also a destination for kayaking.
