Visitor Reviews of Nayoro Piyashiri
- Kermit Panza from United States writes:
Skiing around this area is good for a couple of days with plenty of lift access side-country and some hike too. The main ski area, Piyashiri Snow Park, does maintain a closed gate policy. This makes the side-country a little trickier to access as the cat and mouse game has to be played. There are also some longer back-country tours that might be worth an extra day or two. Access from town is straight forward with good parking and basic amenities at the base of the hill. As with Hokkaido generally, this area gets bombed with snow from December through early March. Piyashiri can also be bitterly cold as one can gather from its latitude. While good for snow conditions, cold feet were the norm.
