The Number 7 Northern Cross-Island Road (台7線 / 北橫) connects Taoyuan to Yilan and passes through spectacular mountain scenery. This cache is located at the Sule Bridge (蘇樂橋), which passes over part of the Dahan River (大漢溪), around the 41.7K mark of the Number 7 Road. There’s no need to put yourself in danger bending over the top of the bridge to find the cache. It’s about a meter away from the bridge identification sign set into marble.
