It is the fastest shortcut from Sanbok Road to Busan Port. One of the representative features of the mountain road is the dizzying vertical staircase six stories above ground. The number of stairs is 168, and it is said that there were originally three wells under the stairs. Currently, only one well that was used for drinking water remains, and you can imagine standing in long lines to get water during times of water shortage. It was a meeting place for people of all ages and genders, such as water crabs and water jars, and a source of rumors spreading.
