Forest Canyon Introduction: The Forest Canyon Adventure Maze is in the Wudan Scenic Area of Chuoyuan National Forest Park. The straight line distance between the top of the valley and the bottom of the valley is more than 300 meters. There are planks connecting the dangerous places. The planks are sometimes built with wooden boards and sometimes with branches. It is woven and sometimes cleverly built with fallen wood, extending downwards in a circuitous way according to the mountain, until it reaches the bottom of the valley. The ancient trees here are towering, blocking out the sun and the sky. A mountain spring winds down along a rocky riverbed. Take a sip, and a refreshing feeling will penetrate your heart and lungs, making you forget the heat outside the valley. The temperature at the bottom of the canyon is 3-5 degrees Celsius lower than outside the canyon, but the humidity is much higher than outside the canyon. Therefore, ferns grow all over the mountain here all year round, and there are dead trees lying horizontally and vertically everywhere. Visitors come here to walk on the river bed and sometimes climb the hillside, and the crisp birdsong is endless.
