Taoyuan International Airport is the primary airport for all international flights in Taiwan, as well as the northernmost airport and the largest civil airport in the region. Since the airport transit system became operational, the airport has been seamlessly integrated with the rail transit, making travel more convenient. The "Taiwan Play Art Street" located on the 5th floor of Terminal 2 of Taoyuan International Airport replicates the nostalgic atmosphere of Dadaocheng Historic Street. It offers delicious food, souvenirs, and a free observation deck for up-close views of aircraft, making it the latest social media hot spot.
