Introduction to Laoren Gorge: It is named because the canyon is gentle and very suitable for walking by the elderly. There are large areas of virgin secondary forest growing in the valley, blocking out the sky and the sun. The famous Laolongtan Waterfall is located here, with a drop of more than 30 meters and is magnificent. There is Laolongtan under the waterfall, which is 6 meters deep and has clear water quality. There is also the hard red quartz sandstone wall left over from weathered and collapsed rocks - the "natural big screen", which is a must-see.
