The park's name, Tian'ehu, translates literally to 'Swan Lake', though the reservoir is primarily a water management facility rather than a natural habitat for swans.
The central lake functions as a critical flood-detention basin for the Xinying urban area, designed to mitigate rainfall runoff.
The iconic wooden bridge is the most photographed feature of the park, offering panoramic views of the water and the surrounding Xinying district skyline.
The park's design incorporates an artificial island accessible via bridge, which provides a raised vantage point for observing the reservoir.
The reservoir area is surrounded by a continuous loop trail that spans approximately 2.5 kilometers.
The park is frequently used as a venue for regional cultural festivals and New Year celebrations organized by the Tainan City Government.
Tian'ehu Park, also known as Swan Lake Park, is a prominent municipal green space centered around a large artificial reservoir in Xinying District. The park serves as a major recreational hub for local residents, featuring an expansive lake that acts as a detention basin for flood control. It is characterized by its signature long wooden bridge that stretches across the water, providing a primary pedestrian path. The perimeter is lined with mature trees, landscaped lawns, and paved pathways suitable for walking and cycling. The park serves as a migration stop and habitat for various bird species, making it a local site for birdwatching. Recreational facilities include children's playgrounds and open plazas designed for community events. The park landscape was designed to integrate water management infrastructure with aesthetic public space.
