Batongguan Historic Trail, in the jurisdiction of the Yushan National Park Headquarters, National Park Service, Ministry of the Interior (Yushan National Park Headquarters), was impacted by Typhoon Gaemi in July 2024. There are multiple spots along the west section trail with either soil collapse, soil and rocks piled, fallen trees, or even subgrade erosion or trestle crashed by rocks.
Yushan National Park Headquarters assigned workers for maintenance a few days ago. The obstacles on the west section trail of Batongguan Historic Trail (the part from Dongpu to Yunlong Waterfall (0K to 4.3K)) have been removed, and people can walk the trail once again. However, multiple spots on the trail between Yunlong Waterfall to Guangao (4.3K to 14.7K) have been blocked and have not been repaired yet. Yushan National Park Headquarters will continue to assign staffs to remove them for hikers to walk, and puts in all efforts to repair the west section trail of Batongguan Historic Trail for hikers to be able to reach Guangao as soon as possible.
The soil is weak and cracked, so it is hard to repair the trail
The soil at the west section trail of Batongguan Historic Trail is cracked and unstable. Major and minor collapses occurred often these years. Yushan National Park Headquarters always sends workers to remove obstacles immediately after being notified that the trail has collapsed and is blocked. However, multiple spots of the trail were damaged severely due to Typhoon Gaemi that hit from July 24 to 26. Besides, side slope collapse, fallen rocks and mud flow occur continuously on the trail due to frequent heavy rainfall in the summer afternoon, so trail repair is difficult. Soil piling up and subgrade collapse occur at multiple spots of the trail, from Yunlong Waterfall to Guangao (4.3K to 14.7K). It is hard to pass through.
The date the west section, south section 2 and Mabolasi Hiking Route of Batongguan Historic Trail will be reopen is postponed
After the sea warning was announced for Typhoon Gaemi, Yushan National Park Headquarters has not allowed people to walk long trails such as the west section, south section 2 and Mabolasi Hiking Route. These trails were expected to be available at the end of September and available for hikers. However, the date is postponed because the trail repair is delayed due to weather. Only a part of the west section trail of Batongguan Historic Trail is only available (up to 4.3K) (Yunlong Waterfall). Workers will be assigned to repair more sections of the trail (up to 11.5K) to the degree that hikers can pass through. Fallen trees, rocks and soil collapse will be removed. It is expected that the trail will be available before October 9.
