The lake is not a naturally occurring island chain but rather a result of the inundation of hills following the construction of the Feitsui Reservoir dam.
The water quality in this region is strictly monitored as it serves as the primary reservoir for millions of residents in the Taipei Basin.
The tea plantations surrounding the lake belong to the Shiding area, known for producing high-quality Wenshan Baozhong Oolong tea.
The name 'Thousand-Island Lake' (Qiandao Hu) is shared with a famous reservoir in Zhejiang, China, to which this location is often compared.
The reservoir area covers approximately 10 square kilometers of surface area.
Thousand-Island Lake in Shiding District, New Taipei City, is a reservoir landscape formed by the Beishi River flowing into the Feitsui Reservoir. The area is defined by a series of small, forested hills surrounded by winding, deep-green waters that create the illusion of multiple islands. The terrain is dominated by sloped, terraced tea plantations, specifically the Wenshan Baozhong tea cultivar, which line the ridges overlooking the water. Due to its location within a water protection zone, industrial activity is restricted, maintaining a high level of water clarity and surrounding biodiversity. The primary viewing areas are situated on elevated ridges accessible via local mountain roads. The site is a primary source of drinking water for the Taipei metropolitan area, strictly regulating development and water access. The visual aesthetic is highly dependent on light conditions and the water level of the reservoir.
The highest observation deck along the main ridge road, which provides the widest panoramic view of the island clusters and tea rows.
Bring a polarizing filter for your camera to effectively manage the glare and reflections on the reservoir surface.
Wear sturdy, closed-toe walking shoes as the observation paths are often narrow, uneven, and steep.
Carry sufficient water and sun protection, as there is very little shade along the ridge trails.
Do not attempt to hike down to the water's edge, as these are restricted protection zones and the terrain is dangerous.
Maintain silence as the area is located within a restricted water conservation zone; do not enter private tea fields or pick tea leaves.
