Amusement Parks are often judged by the roller coasters that they have but this it doesn’t necessarily mean that the top 10 amusement parks have the top 10 best roller coasters and although coasters are often rated by their height, it doesn’t necessarily mean the tallest ones are the best. Out of the ten tallest roller coasters, five are located in the USA, three in Japan, one in Australia and one in Canada. Here is a list of the top 10 tallest roller coasters in the world, with the name of the country and theme park they are in and their height.
