The Fuba Mountain-crossing Trail runs from Fushan in Wulai to Lala Mountain in Baling. It goes through the Lala Mountain Nature Protection Zone and the Chatianshan Nature Reserve. There are many giant red cypress trees along the way and it is also an important habitat for many species of wildlife. In the old days, the Atayal people used to take the ancient trail to go hunting, attend wedding ceremonies and visit relatives. During the Japanese Rule, it was designated as a defense line against the indigenous people. Today, the ruins of police stations can still be seen.
