The vertical cave, located at the deepest point of the Narusawa Ice Cave, is a hard activity that involves passing through a low area of only 91 cm in height. However, beyond that lies a fantastic world of ice, with beautiful and mysterious scenery created by nature. The temperature is always kept at 0℃, so even in the middle of summer, you can feel the cold. This is recommended for those seeking an extraordinary and stimulating experience.
