The deer in the valleys, one after another mountain peak, snow in winter, silver moon and sky full of stars have long been beautiful sights that attract hikers. The ecology and landscape on Xiangyang Mountain and Sancha Mountain the trail passes by have their own characteristics. Xiangyang Mountain is the southernmost border of the spread of high-mountain ecology in the Central Mountains, and Sancha Mountain is famous for the vast and magnificent high-mountain grassland and the sapphire-like Jiaming Lake.
