Udo, Island in Jeju-si, South Korea
Udo is a small island just off the east coast of Jeju Island in South Korea. Its terrain is mostly flat with low hills, black lava rocks along the shore, and a mix of white and dark sandy beaches.
Udo was not settled until the late 1600s, when the government established a horse farm there. The island's landscape of dark rock and white shells is the result of volcanic eruptions that shaped it long before people arrived.
The ferry to Udo departs from Seongsan Port on the east side of Jeju, with a crossing of about 15 minutes. Bicycle and electric scooter rentals are available right at the dock, as the roads are narrow and easy to cover by wheel.
Udo's name means 'Cow Island' in Korean, because the hills look like a sleeping cow when seen from the water. It is also the largest of Jeju's 63 offshore islands.
