03. Eram Amusement Park
Eram Amusement Park in Tehran, Iran, much like North Korea’s amusement parks, is a rusting and sad display of rides, including a horrifying roller coaster that whips passengers instantly from one side to the other, cranking their necks in every direction. Theme park expert Stefan Zwangzer calls Iran’s roller coasters the worst in the world. But being the worst, it’s scary as well.
