Jeju works by bus, taxi, and rental car — but your itinerary decides which feels best. As an overseas visitor, factor in an International Driving Permit (IDP), insurance, and parking before you commit.
Rent a car if…
East coast (Seongsan, Udo)
Buses 111/211 reach Seongsan and the ferry to Udo, but connections, luggage, and timetables eat your day. On Udo itself you still need a bike, scooter, or tour.
Multiple regions in one day
e.g. Seogwipo in the morning and Hyewha/Aewol in the afternoon. By bus alone you can lose 2–3 hours to transfers alone.
Family, group, or young kids
Easier with car seats, strollers, and nap-time flexibility. For 3–4 people, rent + fuel often beats several taxi rides.
Sunrise, sunset, or fixed-time spots
First/last buses rarely match Seongsan sunrise or Hyewha sunset. A car buys freedom for cafes and coastal viewpoints.
Remote cafes, viewpoints, “hidden” spots
Many Instagram stops are 15–30 min walk from the nearest bus stop. One car beats repeated bus + taxi hops.
Bus & taxi are enough if…
Mostly Jeju City / airport / downtown
Airport limos 600/800/801 and main lines 240/360 cover the city and airport well. Since 2025, EMV card tap works on all city buses — no T-money required.
You accept 1–2 hour bus legs
One region per day (east OR west) is realistic on transit. Always check last-bus times in Naver Map.
Budget, solo, or short 2–3 day trip
Rent + insurance + fuel often ₩50,000–100,000+/day. Buses at ₩1,200, tourist loops 810/820/880, and occasional Kakao T can cost less overall.
Driving or IDP feels stressful
Rain, fog, and unfamiliar signs add pressure. Bus + taxi with a Korean address on your phone screen is safer for nervous drivers.
Major sights only, slow pace
Theme parks, Camellia Hill, Osulloc, Hyewha Beach — many fit a “bus + one loop + taxi once or twice” pattern.
Middle ground: rent for a few days
- Days 1–2: rent — focus east (Seongsan/Udo) OR west (Hyewha/Aewol)
- Remaining days: bus — city meals, airport, Jeju City stays
- Airport-area pick-up is fast; book 1–2 months ahead in peak season (Apr, Jul–Aug, Oct)
When rental is usually blocked
Indonesia and mainland China are not Geneva/Vienna members and have no Korea IDP mutual-recognition deal — counters usually refuse even with an “international license.” Try day tours, Kakao T, or a chartered van. Hong Kong & Macau IDPs are often accepted.
Taiwan & Vietnam travelers
Korea has a bilateral IDP recognition agreement with Taiwan (since 17 Feb 2022) and Vietnam (since Jul 2023). With an official IDP booklet from your country + home license + passport, Jeju rentals are generally possible. This is separate from the Geneva Convention list — see the Rental accordion for nationality rules.
Default: original IDP booklet + home license + passport + credit card. Online “international license” PDFs are usually refused.
