Tian Ma Mountain, located to the north of Qingzhu Island, has an elevation of approximately 63 meters. It serves as the highest point in Jinmen's northeastern corner and was originally an ROC Army observation post. This hiking trail, transformed from a military outpost, is now open to the general public. Upon reaching the summit, hikers can enjoy a broad and magnificent view, encompassing the coastal areas near Ma Shan, Houyu, and Caoyu, as well as distant sights across the strait to Daxing and Xiaoxing.
