Udo's located to the northeast of the village of Seongsan-ri on Jeju Island and is only three and a half kilometers off its coast. After Jeju Island itself, it is the second largest island in Jeju-si, although it only has a population of 370 people. Udo literally means "Cow Island" in Chinese and the island probably has this name because it looks like a cow lying down. The whole of Udo Island is a lava plateau with some fertile, flat land where the major agricultural products are sweet potatoes, garlic, and peanuts. There's a parasitic volcanic cone, called shoi meori oreum, in the southeast.
Udo can be reached several times a day by ferry from the village of Seongsan-ri.
