What is currently recognized as the world's longest roller coaster?

Steel Dragon 2000 is recognized as the world's longest roller coaster, with a track length of approximately 8,133 feet (2,479 meters). It is located at Nagashima Spa Land in Japan and opened in 2000, setting the record for both length and height at the time. The design incorporates a traditional out-and-back layout, which allows for sustained excitement over its lengthy course.

Other coasters like Intimidator 305, The Ultimate Roller Coaster, and Fury 325 are notable for their height, speed, or unique design features, but they do not surpass Steel Dragon 2000 in terms of overall length. This distinction solidifies Steel Dragon 2000's status as a giant in the roller coaster world and a significant must-ride for enthusiasts.
