Preferred months for this journey: October, November, December. Check the seasonal notes before choosing your dates.

The clearest sea-of-clouds sunrises from Alishan's viewing platforms, cycling weather around Sun Moon Lake, and Tainan's temple courtyards at their mildest.
Cherry blossom rides the Alishan forest railway and the high-mountain oolong's spring pick scents the guesthouses.
