The Liyu Tan Scenic Area (Carp Pond) is located in Puli, Nantou. It is a natural lake with shimmering waves under the sunlight and verdant mountain scenery in the shadow of the water. The 2.2-kilometer-long trail around Liyu Tan is quite gentle. In addition to strolling through the lush forest, you can also take a ride on the park train to enjoy the beautiful lake and mountain scenery.
