Jeju Itinerary Sanbangsan Mountain can be a bell-shaped lava mountain situated on the Yongmeori Coastline. It is actually not a mountain in the normal sense, but a mound of dried lava. Sangbangsan was formed some seven hundred,000 or so years back and it is the results of violent volcanic activity. https://douglasw864ufk2.laowaiblog.com/profile
