Leviathan, Canada’s Wonderland (Toronto, Canada)
This roller coaster is Canada’s tallest and fastest roller coaster. It is just a 3-minute ride, but it features a sudden 306-foot plunge with an 80-degree angle. At the same time, it runs at 148 km/h. You’ll probably think that your 3 minutes on that ride is the longest 3 minutes of your life. You better be prepared before taking the plunge in one of the scariest roller coasters in the world.
