Introduction to Black Dragon Pond: From the Test Heart Pond, walk along the river channel for more than 20 meters, cross the river channel about 12 meters wide, climb the iron ladder on the edge of the cliff, and walk another 10 meters to the " Overpass". The overpass is a crescent-shaped, round-arch bridge with a steel frame, spanning the Black Dragon Pool from west to east like a crescent moon. The turbulent water rushed here and was blocked by the rock mass, causing a huge impact. Over time, a huge stone pool was carved out. The pool is about 20 meters long from north to south and 16 meters wide from east to west. The deepest point of the pool is about 3 meters. Black Dragon Pond follows the shape of the surrounding cliffs and is round on the outside and square on the inside. When you get off the overpass to the edge of the pond, the pond changes shape again and looks like a lotus. During the rainy season, the water flowing in from the dragon trough swirls and dances, stirring up thousands of waves, just like a dancing dragon, with extraordinary momentum.
