Seogwipo-si (서귀포시, 西歸浦市) is the southern district of Jeju island. The main city consists of a rather small urban center and port on the coast, directly south of Jeju's most prominent landmark, Hallasan mountain. However, urban sprawl has seen it extend in a thin strip along the coast westwards up to the township of Jungmun and some of the coastal villages beyond.
