Jiaming Lake is widely believed by geologists to be a crater lake formed by a meteorite impact, rather than glaciation.
The area is home to the endemic Formosan Sika deer, which are frequently sighted near the trail in the early mornings.
The trailhead sits near the Southern Cross-Island Highway, a road known for its vulnerability to landslides and long-term closures.
The hike is famous for the 'Angel's Teardrop' nickname, referring to the lake's deep blue color and oval shape.
The surrounding forest area contains significant stands of Yushan cane and Hemlock trees that are specific to high-altitude temperate zones.
The Jiaming Lake National Hiking Area Trailhead serves as the primary gateway to the second-highest alpine lake in Taiwan, situated at an elevation of approximately 2,800 meters. Located within the Central Mountain Range, the trail provides access to Xiangyang Mountain and Sancha Mountain. The route to Jiaming Lake is characterized by high-altitude alpine grasslands and rare remnant glacial landscapes. Hikers must navigate a challenging, multi-day ascent through protected forest reserves. The trailhead is managed by the Forestry and Nature Conservation Agency, which oversees the surrounding ecological preservation area. It is the designated starting point for the well-known 'Angel's Teardrop' trail, a journey that spans roughly 13 kilometers one way.
The viewpoint immediately following the trailhead ascent offers a clear panoramic vista of the surrounding craggy mountain peaks.
Secure an entry permit from the Forestry and Nature Conservation Agency well in advance, as quotas are strictly enforced.
Acclimatize to the elevation for at least one night in a lower mountain area before attempting the hike to prevent altitude sickness.
Pack thermal, windproof, and waterproof layers, as weather conditions at this altitude can shift within minutes.
Do not attempt the hike without proper high-altitude trekking experience and physical conditioning; avoid hiking during typhoon season when mountain passes are unstable.
The trail is subject to closure during typhoon season or periods of extreme weather; seasonal forest fire protection periods may also restrict access.
Practice 'Leave No Trace' principles by carrying out all waste; stay strictly on marked paths to protect the fragile alpine tundra.
