is a strait
separating Whidbey Island
from Fidalgo Island
, in the northwest part of the U.S. state
. It connects Skagit Bay
, part of Puget Sound
, with the Strait of Juan de Fuca
. Deception Pass is a dramatic seascape where the tidal flow and whirlpools beneath the Deception Pass Bridge connecting Fidalgo Island to Whidbey Island move quickly. During low tides, the swift current can lead to standing waves, large whirlpools, and roiling eddies. This swift current phenomenon can be viewed from the twin bridges' pedestrian walkways or from the trail leading below the larger south bridge from the parking lot on the Whidbey Island side. Boats can be seen waiting on either side of the pass for the current to stop or change direction before going through. Thrill-seeking kayakers go there during large tide changes to surf the standing waves and brave the class 2 and 3 rapid conditions.
