Roller coasters have been the focal point of theme parks for decades, often singlehandedly making or breaking a venue’s reputation for death-defying fun. Although there is a one in 750 million chance that you will die on a Roller Coaster, part of the thrill is in the unpredictability.

While there have been the occasional accidents, these steel and wooden adrenaline boosters offer a ticket to real-life action-adventure in a safe and controlled environment. According to the Roller Coaster Database Census Report, there are close to 4,000 documented roller coasters in the world.

Here's a list of five roller coasters you must try if you're a fan of this type of adrenaline rush.
