Kiso is located along the upper reaches of the Kiso-gawa River in the southwest of Nagano, and at the border of Gifu. The whole valley area at the foot of Mt. Ontake is considered to be one of the most beautiful woods in Japan.
Easily accessible by train or bus, there is plenty to see on the Kiso Valley hike, from the Mt. Ontake to the old inns of Magome.
