Top 10 crazy tourist attractions

Around the world, from Chicago to Arizona to New Zealand to Norway, there are destinations that put any adrenaline junkie's commitment to the test. 

Here are some of the most terrifying tourist attractions around the world.

10. Willis Tower, Chicago

Chicago's famed Willis Tower has attracted tourists from all the over world primarily for its glass-bottom observation window. 

Even when you know the glass is several inches thick and can handle several people at once, it's still a long way down.

9. Stratosphere Hotel, Las Vegas, Nevada

In true Las Vegas spirit, the Stratosphere Hotel boasts an eccentric set of rides right on the roof of the building. 

One is the X-Scream, an eight-person car that tilts out over the city and dangles the car perilously over the edge. The other is Insanity, a massive claw-like ride that extends 64 feet over the edge of the 900-foot tower and spins you in the air.

8. Bloukrans Bridge bungee jumping, South Africa

The tallest commercial bungee jumping attraction in the world is at the Bloukrans Bridge in South Africa. It's 708 feet above the Bloukrans River.

That's a long way down to think about whether the cord will snap at the bottom.

7. Sky Tower, Auckland, New Zealand

If you want to combine multiple thrills into one, consider the Sky Tower in New Zealand, where you can soak in the sweeping views of Auckland at 1,076 feet one moment and plunge to the Earth below the next.

Of course, you are attached to the tower via a bungee cord and will not splatter once you complete your fall. That'd ruin your vacation for sure.

6. Step Into the Void, French Alps

If you're not in the mood for a walk through the Swiss Alps, why not take a couple steps into the French Alps? 

Step Into the Void lets people venture onto a reinforced glass platform to immerse themselves in the surrounding mountain range. Looking down is pretty much unavoidable, but if you've traveled all that way, why bother?

5. CN Tower EdgeWalk, Toronto, Canada

The tallest attraction in Toronto lets people stand right on the edge of the CN Tower and lean over.

To the uninformed spectator, it may look like visitors have a death wish, but each participant is safely harnessed in. When you're nearly 1,200 feet above the ground, you'd better be.

4. Alpspix Viewing platform, Garmisch-Partenkirchen, Germany

Like the Grand Canyon in Arizona, the Alpspix platform in Garmisch-Partenkirchen lets people walk out over the expanse they're taking in.

More than 3,000 feet above the valley below, the dual platforms allow melted snow and ice fall through slatted grates and keep the attraction open all year.

3. Coiling Dragon Cliff skywalk, Zhangjiajie, China

In the northwest of China's Hunan province, visitors can talk a leisurely stroll along the walkway attached to Tianmen Mountain — 4,700 feet above the ground.

The glass-bottomed walkway is more than 300 feet long and only about five feet wide, providing an experience that's sure to leave you clutching the rockface for support.

2. Titlis Cliff Walk, Engelberg, Switzerland

Noteworthy for its distinction as Europe's highest suspension bridge, the attraction sits more than 9,000 feet above sea level. 

There might not be any glass bottoms, but that's not exactly comforting when the entirety of the Swiss Alps rests beneath you.

1. Trolltunga Cliff, Hordaland county, Norway

There are no railings to protect visitors at the Norwegian Trolltunga Cliff. 

If you want to take in the unadulterated beauty of the nearby cliffs and lake, you'll need to mosey your way out to the ledge. But be warned, people have accidentally fallen off, and no amount of Instagram likes is worth such daring.
