5. Sanbang Mountain Cruise
We could appreciate the blissful and picturesque ocean view of Sanbang Mountain, Brother Island, Hexagon Lave cliff of Mt.Songak and Dragon Coast, which have been designated as Global Geoparks, from the Sanbang Mountain Cruise(about 1hour).

It gots its name because the coast line looks like a dragon that is jumping into the ocean. Dragon coast is a sandstone bed created by layers of sand that have been deposited for 10 million years.
1_2 Mt. Sanbang
It is a trachytic tuff lave dome connected to the sedimentary layer of Dragon coast. It is a bell-shaped tholoid that stands tall in the plains of Southwest Jeju.
1_3 Mt. Songak
It is consisting of a cinder in the middle of the crater and its tuff ring, Mt.Songak's peak, which can also be considered as its mouth, has a depth of 69m and has completely preserved its active form.
