The Datun Volcano Group is categorized as a dormant volcanic region, with the last eruption estimated to have occurred approximately 200,000 to 300,000 years ago.
The high altitude and heavy moisture levels support unique montane ecosystems that differ significantly from the lower foothills of the Tamsui District.
The narrow trail requires physical scrambling, making it a favorite for experienced hikers compared to the paved paths found elsewhere in Yangmingshan.
Dense thickets of Yushan cane (Pseudosasa japonica) cover much of the summit ridge, necessitating the use of gloves for protection while holding onto ropes.
Datunshan West Peak is a prominent volcanic summit within Yangmingshan National Park, reaching an elevation of 977 meters. The trail is characterized by steep, rugged terrain requiring the use of fixed ropes for navigation through dense, waist-high arrow bamboo. It forms part of the Datun Volcano Group, a series of dormant andesitic volcanoes. The ridge line offers 360-degree views of the Tamsui River estuary and the northern coastline of Taiwan. Unlike the main Datun Peak, the West Peak is significantly less developed, preserving a more primitive alpine ecosystem. The path is often exposed to strong northeast monsoons, which influence the stunted, windswept vegetation found at higher elevations.
The highest point of the West Peak, providing a clear vantage toward the Tamsui River mouth.
Wear high-traction hiking boots, as the steep, muddy slopes become extremely slippery when wet.
Carry work gloves to protect your hands when navigating the steep sections requiring rope assistance.
Bring a windproof jacket even in warm weather, as summit gusts can be sudden and intense.
Do not attempt this hike during heavy rain or typhoon alerts, as the steep rope sections become treacherous.
Practice 'Leave No Trace' principles by packing out all waste, as there are no trash facilities on the trail.
