The flower festival was our main reason for visiting, but we like to hike so probably would have gone either way. Since it was flower festival, we took a shuttle bus from a subway stop. Highly recommend you buy an Easycard subway pass as it just simplifies your life for subways and buses. Walked around, saw the clock, ate some snacks, saw waterfall which has the appearance of construction for a very long time and the rest of the flowers. My husband hoofed it to top of one of the trails, said you could just make out Taipei 101, I relaxed by the waterfall for a bit and looked at his pictures ;). Overall, if you like outdoors and walking/ hiking, it's a must do any time of year.
