Ganryu Gorge in Gero City is a spot where overwhelming rock walls formed by the great eruption of Mt. Ontake spread out. This magnificent artwork, made of lava from about 54,000 years ago, is about 72 meters high, and experiencing its power makes one keenly aware of human smallness. In addition, the hiking courses leading to the waterfall viewing promenade and the three waterfalls, where you can enjoy the atmosphere of each season, are also attractive. Spend time in harmony with nature!
