No visitor to Seattle should miss out on the chance to take the elevator to the observation deck at the top of the iconic Space Needle, the futuristic building that dominates the city's skyline. From 520 feet up in the air, the views over Seattle are nothing short of stunning, especially if you take advantage of the free telescopes on offer. The Sky City revolving restaurant at the top of the Space Needle is a popular place to celebrate a special occasion, and you need to book in advance if you want to eat out there and enjoy the view, which is especially impressive at night.
