Ishikurogawa Valley

Overview & Highlights

Ishikurogawa Valley is a stunning natural gorge that originates from Mount Jizo, one of the three peaks of the Southern Alps (Minami Alps). The area features well-maintained walking paths that allow visitors to immerse themselves in the serene natural landscape. The highlight of the journey is the viewing platform located at the end of the trail, which offers a breathtaking view of a magnificent waterfall with a vertical drop of 121 meters.

Historical & Cultural Background

The valley is part of a pristine natural environment shaped by the waters of Mount Jizo in the Southern Alps. While there are no specific historical structures or shrines within the immediate hiking path, the area is highly valued for its preserved natural ecosystem and the geological beauty of the Southern Alps region.

Main Attractions

The most spectacular viewpoint is the waterfall observation deck at the end of the trail. From this vantage point, you can witness the powerful force of the water cascading down the sheer rock faces. Along the way, the well-maintained trail allows you to enjoy the soothing sounds of the river and observe the unique topography of the valley floor.
