Jeju Island Travel Guide

Combining Jeju's east, west, north and south coasts on the same day turns your holiday into a hunt for parking spaces. Build separate days for Jeju City/the north; Seongsan–Udo–Manjanggul/the east; Seogwipo–Jungmun/the south; Aewol–Hyeopjae–Hallim/the west; and Hallasan. Four days is a selective first route; five days is balanced.

Don't put your Hallasan climb on the same day as a flight or the Udo ferry. Rain, wind and route closures can change often. Keep your island programme flexible so that an outdoor day can swap with a more flexible coast/museum day.

This guide is for the main island of Jeju. Udo is a separate day route reached by a short ferry; Marado is different; and Miyako or Ishigaki are in Japan, islands of the Okinawa archipelago that require separate flights. Don't mix up island names when buying tickets.

When you land at Jeju Airport, rental companies usually hand over cars at off-site offices reached by shuttle. In addition to your home licence, you need a valid international driving permit issued under a convention Korea recognises, your original licence and your passport; confirm the company's age/card conditions in writing before paying.

Cars where you enter a phone number into the navigation instead of an address are still common. Allow extra time for speed cameras, school zones and car park entrances. Never drive after drinking alcohol; don't treat the legal limit as a travel strategy.

Getting around by bus is possible, but rural connections are infrequent and the walk from the stop to the attraction can be long. Choose Jeju City or Seogwipo as your base and use lines going to a single region each day. Check Naver Map/KakaoMap together with official Jeju transport information; compare a day-hire taxi with the cost of a car for a full day.

The upper sections of Seongpanak and Gwaneumsa, which reach the rim of the Baengnokdam crater, require reservations. Eorimok, Yeongsil, Donnaeko and shorter trails have different reservation arrangements. Register each person with the correct passport details on the official Hallasan system, and have your QR code and ID ready at the entrance.

Reservations generally open on the first working day of the previous month; check the exact calendar on the system. Summit routes have intermediate cut-off times: if you're late, you can't continue. The Seongpanak car park is small; official guidance specifically recommends using public transport.

There are no shops on the trail. Carry water, food, a rubbish bag, a rain/wind layer and soles suited to the season. Winter equipment, summer heat and fog in every season are serious; don't argue with trail closures. Don't choose Gwaneumsa's steep descent when you're tired.

The Udo ferry from Seongsan is a short sea crossing, but the weather, vehicle acceptance and the last return time change. Carry your passport; rental cars are generally only allowed onto the island in limited exceptions. On the island, choose the shuttle bus, a bicycle or a motorised vehicle that meets the legal requirements.

If you want to visit Seongsan Ilchulbong at sunrise, stay in the east; don't underestimate a long drive in the dark from Jeju City. Haenyeo demonstrations and diving spots depend on sea conditions, and photographing the women divers in close-up without permission is disrespectful.

Manjanggul Lava Tube reopened on 30 May 2026 after a long renovation. Inside it can be wet and cool, with uneven ground; check the visitor section, last entry and any temporary closures on the official Visit Jeju page on the day. Rather than forcing the cave into your Udo day, pair it with Bijarim or Woljeongri.

Jeju City is practical for late flights, Dongmun Market and northern transport; commuting to the south coast every day is tiring. Seogwipo is balanced for waterfalls, Olle trails and southern food; the airport transfer is long. On a five-day trip, Jeju City for the first/last nights and Seogwipo for the nights in between works well.

Seongsan suits Udo and sunrise; Aewol–Hyeopjae the west coast and sunset; and Jungmun resorts, families and bad-weather options. A hotel being close to the sea doesn't mean it's on a swimmable beach.

Changing hotels every night adds to luggage and car handling. Two bases are enough. At a rural guesthouse, check that restaurants may close early, how easy it is to find a taxi and whether the free parking is really on site.

At Jeju black pork barbecues, remember that not every 'black pork' sign offers the same quality/origin standard; ask about weight per portion, minimum orders and whether staff cook for you. Gogi guksu (meat noodles), momguk (seaweed soup) and body-warming bomal juk are more everyday meals.

Galchi, or hairtail fish, is served grilled or in a spicy stew; the showy presentation of the long fish can push up the portion size and price. Abalone porridge is a gentler breakfast, while grilled abalone is a more expensive meal. The season and fishing conditions change what's available.

When buying hallabong and local citrus products at the market, distinguish fresh fruit from sugary processed products. At the Dongmun night market, share several small portions rather than standing in one long queue; if you'll be driving, don't drink any alcohol at all, Jeju soju included.
