Be sure to bring your camera to capture the flowing cascades of Kaminari-daki Waterfall. If it's raging, you may be able to feel the mist on your face.
Located in Takayama, this cascade of water is worth a look. But you'll find plenty more to see and do in this area. Shiga Kogen Ski Area, Jigokudani Monkey Park, and Yudanaka Hot Spring aren't too far from Kaminari-daki Waterfall.
