First time of skiing which is nice and a wonderful experience as there has beautiful view, nice restaurant, comprehensive services. Definitely would recommend for the other travellers who are still considering or interested.
My friend and I visited the site on January 6, 2026, and happened to encounter a blizzard. The scenery under the blizzard was absolutely stunning, and every spot along the way to the attractions was worth taking photos of. Although the final fake sky mirror was a bit less impressive, the other scenery, both inside and outside the attractions, was definitely worth seeing.
The package includes most ski equipment and ski passes. The instructions for exchanging equipment and redeeming items are very clear. The facilities and equipment on-site are all new, but helmets are not included and must be purchased on-site.
