17 Space Needle; Seattle, Washington
The Space Needle ranks among the quintessential visual landmarks of Seattle, and draws nearly 40 million annual visitors, who flock to the spire for its panoramic view of the city’s skyline and surrounding island geography. However, despite the fact that it’s a pleasant night-sky sight, you’ll find few tourists at the peak; it costs $29 just to ride to the top—not something many would dish out for more than once.
