Watch the sunlight dancing on the water as it flows over Jinyue Waterfall. Keep a lookout for pretty rainbows in the mist.
You're spoiled for sightseeing choice in Nan-ao. Jinyue Waterfall is an ideal place to start here, but there are loads of other fine places to experience. Guishan Mountain, Nan'ao Atayal Museum, and St. Joseph's Catholic Church are close to the cascade of water and will top off your day nicely.
