The park has rich and diverse animal and plant resources, including coniferous and broad-leaved tree species such as hemlock, Taiwan cypress, red cypress, Armand pine, Kunlan tree, Quercus serrulata, and Schima superba in the upper forest, and shrubs such as white-flowered star anise, alpine new Litsea cubeba, jade gray wood, deep mountain wild peony, and horse chestnut tree in the lower forest. Among them, the Kunlan tree is a glacial relict plant and is even more precious. The scenery has its own unique charm with the changing seasons. In spring, there are azaleas, in summer, there are alpine flowers such as lilies and foxgloves, and in autumn and winter, there are red-leaf trees such as Taiwan red maple, mountain lacquer, liquidambar formosana, and "Yushan false sand pear".

The wooden horse trail located at the foot of the mountain behind the Anmashan workstation is about 3 kilometers long and was an important road for our ancestors to transport felled trees. Following the timber transport track, there are natural original coniferous and broad-leaved forests on both sides. Many wooden bridges are built using local fallen cypress trees, and the air is filled with a strong cypress aroma. The understory is covered with Taiwan scaly ferns and rare ferns, while the valley is full of sapling ferns. In autumn, you can also enjoy the red maple leaves falling all over the ground. In the afternoon, the fog is lingering, as if walking through a mysterious forest.

Behind the parking lot at 48K on the forest road, there is a mountain trail leading to the "Yakou" viewing platform. Along the way, you can see lush and tall coniferous forests such as Taiwan cypress and Taiwan hemlock, as well as the lush green Yushan arrow bamboo landscape. The "pass" at the end point is the ridge from Anma Mountain, Xiaoxue Mountain to Pingshi Mountain, with an altitude of about 2,600 meters. The view is broad. Climbing up to the 13-meter-high observation deck, you can overlook Xiaoxue Mountain to the north, Jiayang Mountain and Jian Mountain to the east, the mountains behind are the Hehuan Mountain Range, and you can see Baigou Mountain and Baxian Mountain to the south. When visibility is high in the southwest, you can also see Yushan Mountain. Further northwest are Shaolai Mountain, Yuanzui Mountain, and Chuanxing Mountain. You can also enjoy the ever-changing sea of ​​clouds or sunset views with the light and shadow. When there is sufficient moisture in winter, you will have the opportunity to see the beautiful scenery of the snow-capped mountains.

The "Tianchi" with an altitude of about 2,580 meters is located on the southern ridge of Xiaoxue Mountain. Although there are no streams flowing into it, it never dries up all year round. When the clouds are misty in the afternoon, the looming lake surface adds to the mystery. Going from Tianchi Lake to Shenmu, you will pass through a mixed forest of coniferous and broad-leaved trees such as hemlock, Chinese pine, and Taiwan azalea, and then you will see the tall and luxuriant sacred tree of the snow-capped mountains - the 1,400-year-old red cypress.
