With the Benxi Water Cave as the hub, the park integrates mountains, streams, caves, springs, lakes and palaeoanthropological ruins. The Benxi Water Cave, a large scale aqueous karst cave, is deep and broad with a 3000 meter underground river running continuously throughout the year.   The natural hot springs at the Spa Temple scenic spot maintain a temperature of 44 degrees centigrade and a flow rate of 400 tons per day and is of great therapeutic value.

Benxi Water Cave was formed when the earth's crust shifted.  The cave's entrance is on the shore of Taizi River  The cave mouth is 7 meters high and 25 meters wide in the shape of a crescent. On the cliff above the cave mouth are four large Chinese characters carved into the rock-“Benxi Water Cave”.   The characters are copied after the personal calligraphy of senior Chinese revolutionary leader, Bo Yibo. The interior of the caves are surprisingly spacious with enough room for 40 boats to operate carrying tourists on a scenic journey through the network of caves.  At its tallest point is the cave is 38 meters high and at the widest 50 meters across. The daily volume of water flowing through the caves is 20000 tons. The river is 7 meters deep at some points and yet the water is crystal clear and the bottom of the river can be clearly seen.  There are intricate and amazing stalagmites and stalactites throughout the caves.
