The gorge's high marble content is the result of limestone deposits undergoing metamorphic pressure and heat over millions of years.
The Liwu River is one of the fastest-eroding rivers in the world, which is the primary driver of the gorge's deepening.
Taroko was the site of the Wushe Incident and multiple historical conflicts between the Japanese colonial government and the Truku indigenous tribe.
The park contains the only section of the Central Cross-Island Highway that remains open year-round for major transit, though it is frequently subject to landslide repairs.
The name 'Taroko' is derived from the Truku language, meaning 'human being' or 'magnificent'.
The park’s ecosystem includes the rare Formosan black bear, which inhabits the higher-altitude remote regions.
The Eternal Spring Shrine's water source comes from a natural spring that flows directly beneath the structure.
The park features a complex system of tunnels, including the Tunnel of Nine Turns, which was manually carved into solid marble.
The plant diversity is so dense that certain areas in the park have been described as 'botanical museums' due to the proximity of different climate-zone species.
The park's marble has been extensively used in regional architecture and decorative stone work throughout Taiwan.
Taroko National Park is characterized by its deep, narrow marble-walled gorge carved by the Liwu River. The park spans over 92,000 hectares, encompassing mountain peaks exceeding 3,000 meters and diverse ecosystems ranging from subtropical to alpine forests. The Eternal Spring Shrine sits directly above a perennial waterfall, commemorating workers who died during the construction of the Central Cross-Island Highway. The Shakadang Trail follows a turquoise riverbed, showcasing the park's distinct marble rock formations. Due to geological instability, specific trails such as the Zhuilu Old Road require pre-registered permits and have strict daily quotas. Visitors encounter significant elevation changes as they travel from the coastal highway into the high-altitude mountainous interior. The park serves as a critical habitat for various indigenous Taiwanese species, including the Formosan rock macaque and several endemic bird species. The area remains subject to frequent geological activity, including tremors and rockfalls, which necessitate periodic trail closures for safety assessments.
The Swallow Grotto (Yanzikou) offers the most concentrated views of the marble canyon walls and the river below.
Always check the official park website for real-time trail closure status before departing as geological conditions change daily.
Wear a safety helmet when entering designated high-risk rockfall zones to protect against falling debris.
Carry sufficient water and snacks as retail options are limited once you enter the deeper sections of the gorge.
Do not attempt to swim in the river, as water levels can rise instantaneously due to upstream rainfall and strong undercurrents are common.
The park is open year-round, but individual trails close indefinitely for repairs following seismic activity or heavy rainfall.
Remain on marked trails to avoid unstable terrain and respect indigenous territory by not trespassing into restricted tribal areas.
