Get up early in the morning to scuba dive in Kenting’s tropical seas on Taiwan’s southern coast. Then in the afternoon, cross the Tropic of Cancer and don a down jacket to release a sky lantern in the mountain village of Pingxi. This kind of day trip, covering almost 400 kilometers, doesn’t require ruby slippers like Dorothy from The Wizard of Oz or Sun Wukong’s magical cloud. All it takes is the Taiwan High Speed Rail (THSR) to make this kind of adventure possible in a single day.
