Udo is the little island sitting off Jeju's east coast, reached by a ferry crossing of ten to fifteen minutes from Seongsan Port or Jongdal Port. It is only a few kilometres long and wide, ringed by a quiet road of roughly seventeen kilometres, with fields of peanuts and barley, a lighthouse park, a green headland called Udobong and beaches of pale coral sand. Most visitors rent an electric bike, scooter or small electric vehicle at the pier and loop the island at their own pace, stopping for coffee, seafood noodles or the island's famous peanut ice cream. It is a marine provincial park, so a small admission fee is charged alongside the ferry fare. Allow at least three to four hours on the island, more if you want to swim or linger over lunch.
Getting there
Ferries run in the daytime from the east-coast ports, with crossings of ten to fifteen minutes and frequent departures that depend on season and sea conditions. Bring photo identification, because staff check passengers at the pier. Rough weather can halt the boats, so check the day's schedule and the last return sailing before you set out, and never plan an important connection for the evening after your Udo trip.
Outside vehicles are restricted on the island, with exemptions such as electric rental vehicles, so you generally leave a rental car on the main island.
Getting around
The loop road is mostly flat and shared by walkers, cyclists and small electric vehicles, so choose your wheels to match your group. Electric bikes and scooters are the most popular, small electric cars suit families, and walking the whole loop without stops takes about three to four hours. Highlights include the lighthouse park, the climb up Udobong for a view over the island, the coral-sand beach and the small cafes that line the shore. Rent early on busy weekends because vehicles can run out by late morning.
Planning the day
Combine Udo with Seongsan Ilchulbong in one east-coast trip. Take the first ferries across, tour the island, have lunch there, and return mid-afternoon to climb the crater or walk the shore. Bring a hat, sunscreen and a light windbreaker, because it is open and breezy. In winter the island is quiet and cold, with fewer cafes open, while spring brings flowering fields and summer brings swimmers. Keep some cash for small stalls and vehicle rental.
