The tunnel was cut under Japanese rule and sat unused for decades. Now it is lined with LEDs: a rainbow lane, a figure-eight loop of light, flowers glowing like flames, and a 32 m video wall near the end. It only opens at 2 pm, so the sweet spot is to walk in around dusk and come out after dark. The moss tunnel is right next door.
