Unryu Valley (in Nikko City, Tochigi Prefecture) is the general name for the valley area that starts from the middle of Mt. Nyoho, one of the three major mountains of Nikko. Unryu Valley can be enjoyed throughout the year with hiking during spring, summer, autumn, and in winter, when it becomes a popular place for ice climbing also. Many people go on trekking tours to see the huge ice falls that appear only during the severe winter season which starts from the end of January to the middle of February every year. The icefalls created by nature, which can only be seen for about three weeks, are simply amazing! How about visiting there as a winter activity in Nikko? The "Nikko Discount Ticket" is convenient for sightseeing in Nikko.
