Deception Pass is a narrow, tidal passage between Fidalgo Island on the north and Whidbey Island on the south in Skagit and Island counties. It is subject to strong tides and perilous to inexperienced navigators. In 1790, this feature was named Boca de Flon by Manuel Quimper. The same name was charted by Juan Francisco de Eliza. In 1792, Capt. George Vancouver named it Port Gardner, not knowing that the channel was open at the west end. When Joseph Whidbey of his command found the western outlet, Vancouver renamed it Deception Passage, because he had been deceived as to its nature. In 1841, Cmdr. Charles Wilkes used Vancouver’s name on his charts. The name has since been shortened to its present form.
