Located on the Bagua Mountain Range, the Houtanjing Sky Bridge connects the two mountains and resembles a smile hanging in the valley, so it is also called the “Smiling Staircase.” The bridge is 204 meters long and is the longest staircase in Taiwan. The view from the bridge is excellent, allowing you to see the Changhua plain from a distance, and when the weather is good, you can also see the Xiluo Bridge and the Jhuoshuei River from a distance.
