The river is also known as the 'Mysterious Valley' due to the deep, turquoise coloration of the water caused by suspended mineral particles.
The trail route was blasted into the marble cliffside by the Japanese during the colonial period to maintain a water conduit.
The rock faces along the trail provide a geological window into the metamorphosis of limestone into marble over millions of years.
The area is home to the Truku indigenous tribe, and the trail was historically used by local hunters and foragers.
The deep river pools are a result of the Shakadang River's rapid erosion of the crystalline marble bedrock.
The Shakadang Trail is a 4.1-kilometer riverside path located within Taroko National Park, following the turquoise waters of the Shakadang River. The trail was originally constructed in the early 20th century to provide maintenance access for a small hydroelectric dam. It is carved directly into the cliffside, showcasing the dramatic folds of marble rock strata typical of the Taroko Gorge landscape. The path is relatively level, following the contours of the valley rather than climbing steep terrain. Vegetation along the trail includes rare limestone-loving plants and diverse subtropical forest species. The riverbed is characterized by large, smoothed boulders and deep, clear pools. The trail ends at the Sanjian House, which serves as a turnaround point for most hikers. Due to its location in a narrow, seismically active canyon, portions of the trail are occasionally restricted following geological events or heavy rainfall.

Carry a lightweight rain jacket even on sunny days, as the canyon microclimate can fluctuate quickly.
Focus your gaze on the riverbed pools rather than just the cliffs to see the varied rock patterns and potential local fish species.
Bring a reusable water bottle, as the trail is long and lacks vending facilities once you depart the entrance area.
Attempting to swim in the river, which is prohibited for safety and conservation reasons.
Trail sections are subject to unannounced closures due to rockfall, landslides, or severe weather conditions; check official park bulletins before departing.
Stay on the marked path at all times, do not remove any rocks or flora, and pack out all trash to preserve the fragile canyon ecosystem.
