Ninety [%] people come to Signal Hill Park to rotate the environment building. It used to be a signal tower built by Germans. After renovation, it is open for sightseeing. The ticket of Signal Hill Park is five yuan to come to the sightseeing building, which is ten yuan. From the entrance and exit of the two parks, it is still striking that you can walk the stairs for about 10 minutes, because the two red spheres can also get a discount if you buy tickets in advance. Signal Mountain Park plus the viewing building is about ten yuan. There was an uncle at the door checking tickets. After entering, he could see some murals and old photographs. He went up the revolving ladder and up to the top was the viewing platform. The viewing platform is constantly rotating, you can see the whole Qingdao skyline in the direction of 360 176 here, southeast and northwest, and there will be radio announcements, the central place is souvenirs, as well as food outlets. There are about 20 stools and several tables. They are tired of walking. If there are seats on them, they can sit down and turn slowly. Only when you come here can you really feel the green trees and red tiles of Qingdao, especially the greeting building next to you can be seen clearly. Anyway, there is no limit to time. It's no problem to sit here for a day. It's still a place worth coming up. It's cost-effective.
