Jeju Itinerary Sanbangsan Mountain is a bell-formed lava mountain located around the Yongmeori Coastline. It is really not a mountain in the traditional perception, but a mound of dried lava. Sangbangsan was shaped some 700,000 or so years in the past and it is the results of violent volcanic action. https://saddamf319juf0.wikipresses.com/user
