Just a few weeks ago a new sport venue opened in Taipei - Ski School Taipei 台北滑雪學校. It's located in Neihu 內湖 (very close to Costco).
The set up is very simple - a giant slanted treadmill with brand new ski/snowboard boots and skis/snowboards and very nice people running it. And that's all that is needed to have fun on skis in Taipei!
