The three major mountains of Tokyo Disneyland is Big Thunder Mountain, of course. It can be called the most classic out of the three roller coasters, taking you to mid-19th century California and its Gold Rush. Big Thunder Mountain was once a gold mine that was abandoned, but an unmanned rogue locomotive is still running on its tracks. It takes you up the slope slowly, snaking through the atmospheric mine before picking up speed after a sudden drop. At one point, it even seems like you’re about to hit your head! The many thrills of this ride are sure to make fantastic memories.
