Udo โ the island proclaiming the dawn
Udo island is a volcanic island which leads its formation since the Pleistocene, about 11ย 000 years ago. The whole island is lava plateau, which means it was formed by basaltic lava after numerous successive eruptions. It is named โUdoโ (์ฐ๋) which literary translates as a โCow islandโ because it resembles a lying cow.

Udo was first inhabited during Joseon dynasty (around 1679 year). Back then the government built a horse ranch, therefore the first inhabitants were workers responsible for the management and raising of the state-owned horses. (Actually, Jeju island is famous as the only or the main place in Korea where horses are being bred.)

Getting to the island
The only means of transportation to the island is a ferry. There are two ports at Jeju island from which you can catch the ferry for Udo: Seongsanpo and Jongdal-ri. The ferries between Seongsanpo and Udo are more frequent than those between Jongdal-ri and Udo. Actually, there is one going from Seongsanpo to Udo every 30 minutes. The ride lasts approximately 15~20 minutes. The round ferry ticket costs around 10ย 000 won. The ferries from Seongsanpo to Udo runs as early as 8:00 oโclock to 18:30 in the peak season. The last one from Udo to Jeju is at 18:30 oโclock, but it varies depending on the month.
There are two ports at Udo island, too, but it doesnโt matter from which one you will catch the return ferry. Also, the time schedule of the ferries is the same for both ports.

How to get to the port
In front of Seongsanpo port there is a big and free parking lot. For the people planning to use the public transportation there is a direct bus from Jeju bus terminal to the port.
- Blue buses: 201, 211, 212
- Red buses: 112, 111
As for the people traveling from Seogwipo city, blue bus 201 goes from the Seogwipo bus terminal to the port.
Exploring Udo Island
Visiting Seongsan Ilchulbong might take you as little as an hour, but that time is totally insufficient for exploring Udo island. If you donโt want to miss anything, the bare minimum of time that is advised to be spend for the island is around 3 hours.
Means of transportation
There are several ways to move. First and most convenient one is by car. You can take your own car on the ferry to Udo and drive it along the island.ย Second one is by the public transportation. Yes, the island might be extremely small, but there are actually two buses running around it.

There are a red and white one and their routes almost coincide. Both are running around the circumference of the island with the exception of a small part of the red busโs route. In order to ride them, you have to buy a ticket that is valid through the whole day no matter how much you get on and off. The ticket costs 5ย 000 won and can be purchased from a booth located approximately 100m left from Udoโs Cheonjin port. The ticket is valid for both but the white one has a Tmoney validator, too. The buses run every 15 minutes and they go only one way starting and ending at Cheonjin port. When getting on it the driver will explain everything.

The third way is by renting a bicycle or a very small electric car. And the last one is exploring the island by foot but bear in mind that it is bigger than it might look like.
Things to do
Udo island is very small but extremely beautiful and worth a day to be spend there. The island has its own list of sights:
- Jugan Myeongwol(์ฃผ๊ฐ๋ช ์): a sea cave where the sun appears like a moonlight glow in the middle of the day
- Dongan Gyeonggul(๋์๊ฒฝ๊ตด): a cave beneath the cliff of Geommeolle beach
- Jidu Cheongsa(์ง๋์ฒญ์ฌ): the views from Udobong
- Seobinbaeksa(์๋น๋ฐฑ์ฌ): a white sand beach along the west coast. The sea around this beach alters colours depending on the water level. Seobinbaeksa is the most famous beach at Udo as it has appeared regularly in films and TV commercials. But besides it, the other beaches at Udo are also equally good.
- Udo Olle Trail(์ฐ๋ ์ฌ๋๊ธธ): this trail goes around the entire circumference of Udo, presenting a scenic view of the coast line.

Along the coast there are numerous cafes, restaurants and souvenir shops with a mesmerizing view.
