Snow, rare in the rest of Taiwan, is relatively common on Mount Hehuan during the winter months. Highway 14 leads to Wuling, a saddle between the main peak and the east peak of Hehuanshan. At 3,275-metre, Wuling is also the highest point of Taiwan accessible by highway. From Highway 14, a trail leads to the summit of the main peak. At the summit, there is a weather station.
