The frozen waterfalls of Unryu Keikoku 雲竜渓谷の滝

Lavallee of the mist

Unryu Keikoku is a natural valley formed between the Nyoho and Akanagi Mountains. Nicknamed "the valley of the cloud dragon," Unryu Keikoku is trapped in a natural mist throughout the year! A feature that allows it to offer landscapes of incredible beauty whatever the season.

With their 80 meters high, the stalactites created by the ice hypnotize more than one. Confined to the hollow of the valley between the snow and the water of the stream, they spring from the winter mist to form a striking picture that one would not suspect the existence only two hours from Tokyo.

The hiker's paradise

For a few years, the spot has become a must for mountain hikes.

Indeed, the valley offers an excellent 9 km course on the heights of Nikko. A 5 to 6 hrs hike highlights the relaxing landscapes of Unryu Keikoku.

Two routes are then possible to reach the waterfalls: a path on the heights of the valley which takes the usual ways, and a more modest path which goes up the course of the stream on the side of the hill.

Each route has its advantages since the first offer magnificent panoramas while the second offers a more intimate immersion in the heart of nature.

Caution is the mother of safety

The best season to come and admire the ice falls remains from the end of December to the beginning of March.

The snow being quite thick at this time of year, a few safety instructions must be followed if you don't want to have any unpleasant surprises.

First, bring good shoes. Although snowshoes are not essential here, crampon shoes will make it easier to walk in the valley. As temperatures are low, don't forget gloves and warm clothes.

Finally, remember always to be careful. And that the ice could break at any moment. So don't get too close to these suspended beauties!
