Situated between Jingtong Station and Pingxi Station of the Pingxi Branch Line, Mt. Xiaozi is not as tall as the other mountains, but its steep stone steps are not negligible. The most adventurous route when climbing Mt. Xiaoxi is the last way to the summit on the suspended steel ladder. Once successfully climbing up this near-vertical rock walls, tourists can take a bird's-eye view over the entire Keelung River Valley. Due to its being surrounded by mountains, there are about 20 hilltops in the neighborhood, that's why it won its name as Mt. Twenty-Four Filial; and because its mountain shape is very similar to China's Mt. Huangshan, so Mt. Xiaozi is also nicknamed as the "Small Huangshan."
