7 of the world's most terrifying theme park rides

Two carriages on the Smiler rollercoaster smashed into one another leaving four people seriously injured.

But with theme parks always pushing the limits, rides are becoming increasingly frightening.

Here's a list of some of the world's most terrifying park rides that you definitely wouldn't want to get stuck on.

Takashiba

Height: 141ft

Speed: 62mph

Location: Fuji-Q Highland theme park, Japan

So this death trap in Japan is the world's steepest roller coaster.

It takes riders up a 141ft climb before dropping them at a 121° angle.

(For those that don't know what that means, it's pretty f****** steep)

The name is a pun which translates to "high fly car".

Probably not as funny as they intended.

X2 rollercoaster

Height: 190ft

Speed: 76mph

Location: Six Flags Magic Mountain, California

This is the first 4D (not G) roller coaster.

Riders get spun in, out, in, out and shaken all about as they hurtle down a track at 75mph.

Keen roller coaster…ers get taken up the initial climb backwards and then dropped from 190ft.

Nice view though.

Giant Canyon Swing

Height: 1300ft

Speed: 50mph

Location: Glenwood Caverns, Colorado, US

This giant swing sits 1300ft above the Colorado river.

Maniacs travel from all over the globe to go on the 50mph "ride" – which photos of are even a struggle to look at.

Brave souls are forced to sign a waiver form before entry in case the five minute experience results in their DEATH.

Thank goodness for that piece of paper, aye?.

Wicked Twister

Height: 215ft

Speed: 72mph

Location: Sandusky, Ohio

If you don't like corkscrews, look away now.

This winding, twisting, crossing – and quite frankly mind-bending – roller coaster looks like something from a nightmare.

Carriages are set off at 70mph up a 215ft part of the track which screws to…well, nowhere.

Riders are then dropped down backwards to really bring in the dizziness.

Not for the faint-hearted or those who are breathing – so everyone.

Insanity

Height: 900ft

Speed: 40mph limit

Location: Statosphere, Las Vegas

Most go to Vegas for the gambling, booze and partying.

And some have got to experience Insanity – which sits 900ft above the brightly-lit strip.

With a maximum spinning speed of 40mph, just a seat separates daredevils from certain death.

Yet visitors still seem to love it.

What happens in Vegas, should definitely stay in Vegas.
