Easy nature walking day tour in Oni-iwa Valley
Oni-iwa valley is about one-hour drive from the central Nagoya. You can have a 2-hour walk in the mountain, especially along the stream. It’s an ideal afternoon walking experience. If you are tired of busy urban settings in Nagoya, take a half day tour to breathe fresh air in forests.
Oni-iwa is not in a deep mountain though it shows an unique natural feature. The bottom of a small valley is filled up with large rocks. It was believed that an oni (devil) lived in this hidden valley. Thus the name Oni-iwa means ‘devil rocks’.
At the entrance of the valley, there are two waterfalls. These falls are called “Meoto Daki”, which means “wife and husband falls”. Water in the pond is not clear but this is due to the rain.
There are many rock walls. Unfortunately, bordering is prohibited in the park.
You sometimes go underneath the piled huge rocks. There is a special route which largely goes through a tunnel underneath the rocks. Unfortunately, this special route is open for the public only on the particular days of the year, due to the danger to fell off into the stream.
In the uppermost area of the valley, you walk in natural forest.
This beautiful fern is an example of wet vegetation.
At the viewpoint. A rewarding panorama view.
