The original battlefield is located at about 1400 meters above sea level, and is one of the representatives of the Japanese plateau wetland. It grows with all kinds of plants and animals, and it shows mysterious beauty under the influence of seasons and climate. It is said that the alpine plants in summer are especially beautiful, and the autumn grasslands are bright red and golden yellow. The battlefield was originally a vast plain, composed of reed forests and jungles, dotted with some birch forests. The original battlefield was built with the Austrian Sunlight Nature Trail, which traveled along Tangchuan, and the end of the flowing water was the leading waterfall. Walking on the wooden path of the tourists on foot, the birds screamed from time to time. Visitors can get close to the mountains and rivers of nature, and enjoy the original flora and fauna of the entire battlefield and the male mountain overlooking the distance! Starting from Tangzhi Lake, the target is the red marsh of the original battlefield. The whole journey is about 8 kilometers.
