Lake Longtan, also called Longtan Large Tourist Pond, is the most famous landmark in Longtan, Taoyuan. Originally, the pond functioned as an irrigation pond. Since the establishment of the extraordinary temple, “Nantan Temple” on the small island in the lake, the landscape has become very elegant. Against the backdrop of the Longtan Suspension Bridge, Longtan Large Tourist Pond has become an important recreation area that attracts tourists.
The lakeside park and the Lombard-style Chung-Yi Bridge of the Tourist Pond are both distinctively beautiful, especially at night when the light brings about the contrast. It soon became a popular dating spot for couples.
