Peaks are also known as ridges or mountains. They stand out from the surrounding mountainous terrain and are mostly located on the tops of ridges. The side view of Hengcheng Peak provides the best illustration of the relationship between peaks and ridges. Peaks can be sharp, round, columnar, and flat topped. A mountainous area often has multiple peaks, and they are often eye-catching. Examples of peaks are Mount Everest in the Himalayas, the West Peak in Huashan, Zhu Rongfeng in Hengshan, Tiandu Peak in Huangshan and Tianzhu Peak in the Taishan Mountain, which are popular destinations for tourists.
