Seattle · West Point & Alki Point
Elliott Bay & Puget Sound
Seattle's waterfront between two lighthouses, with the ferry lanes of Puget Sound at its feet.
West Point Light, at the tip of Discovery Park, alternates white and red across the Sound, answered by Alki Point's single flash to the south. Between them lie Elliott Bay, Shilshole and the ferry routes to Bainbridge, lit buoy by buoy.
