The Tunnel Hill (Chuanshan Hill) is situated in the southeast. It took its name from a cave which extends through the Hill from north to south. From a distance, the cave looks like a full moon. Therefore it is also known as the Moon Cave . The Cave is located at the foot of the Hill and boasts crystal needles, stone twigs, and stone goose feathers that are seldom found in the more famous Reed Flute Cave and Seven-Star Cave . A branch of the Li River winds through the park.
Situated south of the city and on the east bank of Li River, Chuanshan Hill Park covers an area of 2 square kilometers with the Chuanshan Hill as the axis. It faces Elephant Trunk Hill across the Li River and stands against the Turtle Hill on the west bank. Two hills look like two fighting roosters, hence the name Rooster-fighting Hills. Tower Hill is in front of the Chuanshan Hill with Shou Fo Pagoda from Ming Dynasty at the top. Xiaodong River runs between the two hills presenting picturesque reflections on the water.
