Uiwang Rail Bike is a manual rail bike facility that runs a loop around Wangsong Lake in Uiwang. Four-seat bikes are pedaled by riders, passing cherry blossoms and autumn foliage along the way. Tickets depart together at set times, with a rest section in the middle, and the full ride takes around 40 minutes. It is hot in summer and strenuous enough that at least two adults need to pedal.
