Taitung Airport is at the out edge of the main part of Taitung city. The airport is small, however, Taitung area have two important resort island - Ludao 綠島 and Lanyu 蘭嶼, so if you come from Taipei and go to visit these islands quicky, you'll use this airport (from Taitung to these island, also ships are available and costs rather low anyway).
The cache container is 100mL medicine bottle.
Note:
As you see... the cache is in usual park, but anyway :-) , it's very near from airport... so please don't do any strange action when hunting; read the hint and hunt quickly
