Daily Air (http://www.dailyair.com.tw/) website in Chinese only has around 6 flights a day from Taitung to Orchid Island's airport on the central west coast. You can easily become stranded on the island for days when winds pick up even during non typhoon weather. Daily Air will cancel flights when the winds are even as low as 35 miles per hour. You can also take a ferry from Taitung, but be aware that the seas can be VERY rough.
