The trail follows an ancient hunting path originally used by the indigenous Truku tribe before colonial expansion.
The cliffs were formed by the rapid tectonic uplift of the Liwu River, exposing massive marble deposits over millions of years.
The trail reaches heights where the air pressure is noticeably lower, and cliff-edge vegetation includes rare orchids adapted to limestone environments.
Parts of the trail were used by the Japanese colonial government to monitor movement across the Central Mountain Range.
The trail is prone to rapid weather shifts; clouds often get trapped within the narrow gorge, creating significant visibility changes.
Zhuilu Old Road is a historic mountain trail carved into the vertical marble cliffs of Taroko Gorge at an elevation of approximately 700 meters above the Liwu River. The trail segment known as the Zhuilu Cliff is only 90 centimeters wide in sections, featuring a steep drop-off directly into the canyon floor. Originally constructed by the Truku indigenous people, it was later widened by the Japanese during the 1920s to facilitate colonial administration and military surveillance. Hikers traverse suspension bridges, mountain tunnels, and cliff-side paths that offer panoramic views of the narrowest part of the gorge. The trail spans a total length of approximately 10.3 kilometers, though hikers are currently restricted to the 3.1-kilometer segment between the Zhuilu Suspension Bridge and the cliff site. Due to the high-risk terrain and landslide vulnerability, entry is strictly regulated by the Taroko National Park authorities. The environment is characterized by distinct limestone geology, unique cliff-dwelling flora, and high-altitude microclimates.

Apply for the required mountain entry permit well in advance, as daily visitor quotas are strictly enforced.
Bring a headlamp or flashlight for the unlit tunnels located along the cliff path.
Check local weather reports specifically for Taroko National Park, as heavy rainfall frequently triggers mandatory trail closures due to instability.
Do not attempt the hike if you suffer from severe vertigo or fear of heights, as the exposed cliff path has no secondary railings in some sections.
Trail access is subject to immediate closure during and after heavy rain, typhoons, or seismic activity.
Hikers must carry official permits at all times, remain on the marked path, and strictly adhere to 'Leave No Trace' principles due to the sensitive karst ecosystem.
