Tainan night markets are not opened in the same location every night. The 3 famous night markets are Shilin in Taipei, Fengjia in Taichung and Flower market in Tainan.
Hua Yuan Night Market (Huāyuán Yèshì 花園夜市)
Thursdays, Saturdays and Sundays; Haian Road, Section 3, between Lixian Rd. and Hewei Rd., North District. This is the largest night market in Tainan, and the largest fully-outdoor night market in Taiwan. Ample parking is provided here.
Da Dong Night Market (Dà Dōng Yèshì 大東夜市)
Mondays, Tuesdays, and Fridays; Linsen Road, Section 1, near Chongde Rd., East District. This is the second largest night market in the city. It is very popular on Friday nights, especially with NCKU students.
Most of the stalls are repetitive. Taxi driver explained that rather than locals travel to the night market , the night market stalls travel to be near residents so that you don’t have to travel too far to visit one.
If you’re unsure, just pick up a Tainan tourist map. Google map also tells you which market is opened on the relevant nights. So get your unlimited wireless access which is accessible across Taiwan and so handy when you are on the train.
Tainan night market is interesting and possibly one of the only entertainment for locals. There’s food and games. Reminds me of my childhood.
All kinds of entertainment from archery to shooting to fishing for prawns and then BBQ onthe spot.
Consult the guide map and the link provided above. Best to ask the taxi driver or the hotel you’re staying at.
