One of the first things to do when visiting a new city is to check out the sites that make it famous. But are those popular tourist spots really worth the crowds?

If you're going to China, you can’t leave without visiting the Great Wall, right? And if you’re in Seattle, you must visit the famous Space Needle – it's one of the best observation points in the world. Traveling to New York City? Your visit isn’t complete without a trip to the Statue of Liberty.

There's a reason why millions of people are drawn to these big attractions each year.  They offer opportunities to learn about a different culture or explore religious sites, landmarks, museums and natural landscapes.

Not all tourist attractions live up to the hype-- but these are some of the many that do.
