The red ball viewing platform of Qingdao's Signal Hill Park is also a landmark of Qingdao. The mountain is not steep, and the steps are up. You can only smell the birds in the silent woods cheering, and the church not far away hears the melodious bells. Arrive at the 360-degree rotating observation deck, and you can see the whole picture of Qingdao. The red tiles and green trees in the old town, the blue sea and blue sky; the skyscrapers on Hong Kong Road are towering into the clouds; the Lushan Mountains in the distance are rolling and rolling; the tickets are not expensive, and it only costs 10 yuan to buy online.
