Hudongshui Scenic Area is located on the north side of Huangsongyu Reservoir in the northeast of Pinggu District, Beijing. It is a canyon with a length of about a few miles. It was only developed and built in 1989. It has a total area of 9 square kilometers, 5,000 meters in length from east to west, and 1,500 meters in width from north to south. It is named after lakes in the valley, caves in the mountains, and streams often flow. The lake caves and mountains are weird, the canyons are quiet, the mountains are dense, and the water is beautiful. The scenery of the four seasons is different: the mountains are blooming in spring, and the birds are singing; the green water in summer, the curtains are full of mountains and rivers; the mountains are full of fruits in autumn, and the grass is golden; the winter is wrapped in silver and the glacier is lying sideways. There are cool and elegant summer resorts in the scenic area, with more than 20 landscapes such as Sanniang Cave, Echo Cave, General Cave, First Line Tian, Yanchi Cliff. Walk along the stream, and the first thing you see is the three big words "Lake Dongshui" on the rock wall of the mountain gate. The tall white archway stands where the stream flows out. There is half of the mountain pavilion on the left side of the mountain road. The peaks on both sides of the canyon are towering, looking up at the sky, the sky rises, so the name is the sky. Deep into the valley, the peak circuit turns, and the scenery moves. As soon as I entered the valley, I felt a little cool. There was a stream flowing out. There was a plank road on the edge of the cliff. There was a pool of clear water below. There were several small temples in it. There was a naturally formed Luohan statue on the right side of the recess. Come to Longtan Lake, from the introduction to know that hundreds of years ago, the local mountain people and widowers, in the deep water in the north corner of this pool, often found the figure of the dragon, so the name "Longtan Lake". Later, every time the drought was serious, farmers in Shili Village and Townships, three or five groups of farmers, carried supplies to this rain, very practical. The most spectacular is the slope of about 45 degrees, the ladder made of mountains and stones, almost straight up and down, as if to climb the sky. The 800-level ladder made of mountain stones leads directly to the Niangniang Temple on the top of the mountain. There is a viewing pavilion in the center of the ladder, and it is a "Huaitian Lanyue" archway. Lifting your eyes and looking at the valley, the valley streams and secluded stones in the canyon, and the streams flowing through the secluded stones are hidden and present, showing a dynamic, quiet and harmonious beauty. The lake cave water peaks are weird, the canyon is dangerous, the mountains are dense, and the water show caves are strange. This is really a fun place. Go to the lake cave water from the city to take the 918 tourist bus directly to the scenic spot, or take the 918 bus directly to Pinggu District City and then transfer to the urban and rural scenery car. Tickets are 30 yuan.
