After entering the national park, the most interesting destination is the big Jianshi Mountain standing in the Kenting Ranch. From the west to the south bay to the east to the goose nose, as long as you look up, you can see its towering figure. In fact, the elevation of Dajian Mountain is only 318 meters, only because the surrounding terrain is too low, so it has the feeling of standing out. The Dajian Mountain, composed of sandstone and shale gravel, is the result of long-term geological erosion and then sudden exposure. At present, there are two mountaineering entrances in Dajian Mountain. It takes about 1 and a half hours to climb from the pasture to the east; if you climb to the top from the west, it takes 2 and a half hours, which is a quite easy journey. After climbing to the top, the landscape of the entire Hengchun Peninsula is in the eye and unobstructed. Climbing is now banned, and violators of the National Park Police will be fined.
