Simatai Great Wall is known as "the best of the Great Wall of China" by the famous Great Wall expert, Professor Luo Zhewen, which is rare in China. Named "the world's top ten most can not miss the scenery" top.

The Great Wall from south to north along the ridge, the mountain is not too high. Inside the wall of the city connected to the black valley off the city, built by the mountain, generally rectangular, north and south to about 400 meters, east and west to about 200 meters. Now the north wall also holds a city gate, more broken. Walls are large pieces of river light stone plus white paste masonry, and some places also have stone and brick. From the northeastern corner of the city off the Great Wall through the highway and the river, to the top of the north to a straight under the cliffs, the walls are still some holes and walls of the wall remains, through the clear river, but also To the river there is a large stone of artificial masonry, where the water should be the door of the site. Cliffs on top of a brick hollow tower, the enemy floor is now more complete preservation, even the walls of the arrows and doors included, a total of eighteen vouchers kept, unique shape.

In the southwest of the black valley fort, there is a unique watergate called "five tiger water door off", this gateway is basically well preserved, there are two tall closed the door, the Great Wall was east and west, connecting the two tigers City gate.

If you go to the Beishan beam, you will see the Great Wall into something to the trend, but because of this mountain high road insurance, mountain Liangshan has no building walls, only the enemy floor between the mutual connection and look. The locals said: "the northwest side of the peak of the tower is called the top five, even he did not go over there, where the mountain high road insurance, it is difficult to imagine, that year the people of the Great Wall is how the stone, the city Brick, lime shipped up the mountain.
