Feilada is a transliteration of Italian (via Ferrata, meaning cliff exploration or railway climbing). It refers to the construction of a climbing track composed of steel handrails, pedals and life steel cables on the rock walls of the mountain. The sky and white clouds above your head, the cliffs under your feet, the stalagmite River, the mountains in the distance, and the clouds after rain are like a fairyland. In different seasons and different climates, you have different postures, which also makes you climb on the wall without rock climbing ability, which is very thrilling.
