Gyeongju Ruji World is a theme park in the Gyeongju Bomun Complex where visitors ride a lift up and come down on a luge. Riders put on a helmet, learn safety and operating instructions, then descend a course with sharp curves. It opens at 10 a.m., has a break starting at noon, and tickets can be reserved in advance on the official website. Children under 10 have difficulty riding alone.
