Riguan Peak is located on the southeastern side of Mount Tai and was called Jieqiuyan in ancient times. Its current name comes from the sunset views available from the peak. The western side of the peak is where spirits were supposedly sealed during the Tang and Song Dynasties, while the very top of the peak is home to Yingxu Pavilion. During the Republican Era of China, the Taishan Meteorological Station was built here. Later on, the east side of the peak became home to the Guanri, or “Sun Viewing”, Gallery. On the northeastern side of the peaks are a collection of long, flat boulders that display the might of Mount Tai. The peak features several stone carvings, as well as breathtaking views of sunrises in the morning and colorful clouds in the evening. These views have become symbolic of Mount Tai.
