Of the Columbia Tower, tallest building in Seattle; and the 2nd highest within the west coast US states at 933 ft (284 m).
It is a nice quiet place to relax, unless a fear of heights develops. The floor is open to the public, for a small fee (of which I do not remember). The floor is almost 360 degrees, with nice seats and a cafe.
That land between here and the Sun is West Seattle, surrounded by the Puget Sound waters.
