Da'anxi Canyon is located at the junction of Taichung County and Miaoli County. Because of the earthquake and the torrential rain in recent years, it has formed magnificent canyons and waterfalls. Although it is not as vast as the Grand Canyon Park in the United States, the water flow here is magnificent and clear. Along the way, there are sand bars, mainly composed of various kinds of stones, which belong to a relatively small number of scenic spots. There's no tour group, maybe it's a good place to give full play to your energy and make you take a big picture.
