Introduction to Shanmian Mountain: Yehliu has two Shanmian Mountains, which are connected by a long and narrow sea erosion platform. For the sake of distinction, the Shanmian Mountain near the entrance of Yehliu Geopark is named "Big". Shanmianshan is called "Shanmianshan", while Shanmianshan, which is located at the end of the headland and goes deep into the sea, is distinguished by what the locals commonly call "Guitou Mountain". From the viewing pavilion of Da Danmian Mountain, in addition to overlooking the entire Yeliu Cape, you can also find traces of compression and distortion left by layers of orogeny on the rock wall, as well as candlesticks neatly arranged on the sea erosion platform. Stone, ginger stone and mushroom rock.
