Parking is available at Seongsan Port for vehicles traveling from Jeju City (approximately 1 hour drive east via Route 1112 and Route 1117).

Historical & Ecological Origin

Udo Island was formed by volcanic activity approximately 2 million years ago, as part of the Jeju volcanic region. It is classified as a tuff cone, a type of volcanic cone formed by explosive eruptions. Historically, the island was inhabited by fishermen and farmers, with its name meaning "Cow Island" due to its resemblance to a lying cow.

Key Highlights & Activities

Best Time to Visit

The best months for visiting Udo Island are from April to October, offering milder weather.

Ferries operate year-round, weather permitting.

Facts & Legends
