Initial trekkers in the area were the Taroko group of the Sedekeya Taiyan Tribe. The growing population of the group and frequent fighting with other groups over space forced them to migrate from Renai in Nantou County along the main line of the Central Cordillera, the Hehuan Branch on the westside of the Chilai Mountain northeast. The trip took them eastward along the and the trip passes through Sanzhai Creek before reaching Jiamin Village and Shuiyuan Village, which are the east sector of the Central Taiwan Cross Island Highway we know today. During the Japanese Occupation, the Japanese built the trail for the Taroko tribe in 1914 and it began from Wushe in the west and crossed over upstream of the Zhuoshui River and Hehuan Mountain before taking the Liwu Creek along the Dayu Peak and eventually linking the road leading to Xincheng in Hualien and the trail was known as the Taroko Trail, which covers the entire trip of the Hehuan Cross Mountain Historic Trail .
