Sangumburi, which appears as an impressive location in the movie 'Lotus Wind Love Song', is a natural monument and a crater with a circumference of over 2km. It appears in a scene where Jang Dong-gun (Tae-hee) and Go So-young (Yeong-seo) are walking around Sangumburi. There are about 360 parasitic volcanoes distributed on Jeju Island, but except for Sangumburi, all of the volcanoes here have a crater shape that looks like an overturned bowl, and Sangumburi Crater is the only crater in Jeju Island that erupted without erupting lava or ash, destroying the rocks there. It blew away and only the hole remained. This type of volcano is called Maar, and it is a very rare volcano in the world, with only one in Korea.
In particular, there are many gaps at the bottom of Sangumburi, so all the water seeps in, so the plant ecosystem is uniquely distributed within this crater. It is done. Temperate and subtropical regions are formed depending on the height of the crater's interior, and are distributed in various ways depending on the amount of solar radiation and sunlight hours. So, the sunny northern cliff forms a subtropical zone and is home to a group of evergreen broad-leaved trees, including red thorn trees, cypress trees, old cypress trees, and sendal trees. In the lower layer, rare plants such as eucalyptus orchids, wild berries, and winter strawberries are distributed. there is. In addition, the southern cliff, which does not receive much sunlight, is home to a colony of temperate deciduous trees, including oaks, Japanese oaks, maples, and pine trees, which have a very different distribution from those in the north.

In addition, the Sangsan community, Jeju Korean lily community, Boksangcho community, and Byeonsan wind flower community, including the Chinese eucalyptus community, which are hard to find anywhere else, are very splendid and perfectly preserved, and the research value is highly evaluated. It is also famous as a habitat for wild animals such as mammals such as roe deer and badgers, as well as birds and reptiles. In spring, the clouds that form at the bottom of the crater and rise upward are almost mysterious, and with colorful flowers such as Aster, Murut, Gentian, and Whirligig, this Sangumburi presents mystery and beauty to tourists all year round.
