Tri-Mountain National Scenic Area Headquarters

In the southern border of Miaoli County lies a rare badlands landscape in Taiwan - Huoyan Mountain. With an elevation of 602 meters, the mountain is steep and almost devoid of vegetation, revealing exposed gravel and red soil layers. Located next to National Highway 1, it is known as Taiwan's version of the "Grand Canyon." In recent years, through word-of-mouth among Instagrammers who love capturing fascinating photos, the embankment on the south side of Huoyan Mountain, across from the Da'an River, has become a hidden gem. The desolate landscape of the dried riverbed combined with the backdrop of Huoyan Mountain creates a surreal ambiance, as if being in a different world. Huoyan Mountain features a challenging circular hiking trail that spans 6.4 kilometers. Please proceed with caution after reading the trailhead instructions.

On the eastern side of the highway, there is another hidden gem perfect for a fun family adventure. The Old Mountain Line Railway has transformed century-old railway tracks of the Taiwan Railway Administration into a human-powered rail bike. Spanning 12 kilometers, the route passes through historical landmarks such as Shengxing Station, several tunnels, and the famous Longteng Broken Bridge. Along the way, you can enjoy diverse natural landscapes and the unique experience of riding on an elevated railway.
