The largest giant tree in the grove, Yaya Qparung, has a circumference of 20.5 meters.
Smangus was the last village in Taiwan to receive electricity, not being fully connected until 1979.
The tribe operates under a 'Tnunan' system, a communal lifestyle where income from tourism is shared among members.
The forest is home to endangered species including the Formosan Serow and various montane bird species.
The region maintains a strictly controlled visitor capacity to minimize environmental degradation.
Smangus, known as the 'God's Tribe,' is an indigenous Atayal community located in the remote mountains of Jianshi Township. The primary attraction is a grove of ancient Formosan Cypress trees, the largest of which is over 2,500 years old. Visitors must traverse a 5.2-kilometer round-trip trail that winds through high-altitude primary forest. The terrain includes wooden bridges, cliffside paths, and forest streams. The area remains under the stewardship of the Atayal people, who operate the community on a communal land-sharing model. The forest environment is characterized by high humidity and frequent mist due to its elevation above 1,500 meters. The trail is well-maintained but involves significant elevation changes.

Wear high-traction hiking boots, as the trail can be slippery and muddy even in dry weather.
Bring a layered windbreaker, as temperatures drop significantly when moving from the village to the shaded forest floor.
Carry a trekking pole for the steep sections of the trail, especially if there has been recent rainfall.
Do not attempt the hike in high-heeled or flat-soled fashion shoes; ignore the 'no-entry' signs during periods of heavy typhoon-related rainfall.
The trail may be closed periodically during typhoon season or following significant seismic activity in the Hsinchu mountain range.
Respect indigenous cultural protocols, avoid loud noises, stay strictly on marked paths to protect root systems, and pack out all trash.
