Jeju Island has a reputation as a place where you absolutely need to rent a car. Locals will tell you this. Blog posts will tell you this. And for some itineraries, it is true. But if you are a budget traveller, a solo visitor, or simply someone who does not want to deal with Korean traffic and unfamiliar road signs, you can see a very satisfying version of Jeju using only public buses — and spend a fraction of what a rental would cost.
This guide covers how to get around Jeju without a car, which sights work best without one, and what to realistically skip. If you are still deciding how to reach the island in the first place, see our guide on how to get to Jeju Island for flight and ferry options before you plan your bus routes.
Understanding Jeju’s Bus System
Jeju overhauled its public bus network in 2017 and the result is surprisingly usable. The island runs two types of intercity bus: the express buses (급행버스) that connect Jeju City to Seogwipo quickly along the coast roads, and the local buses (간선·지선버스) that branch off to villages and attractions.
The flat fare for most rides is 1,200 won when you tap with a T-money card (1,300 won in cash). Express buses charge 3,000 won. Buy a T-money card at Jeju International Airport convenience stores (GS25 or CU, both in the arrivals hall) for 4,000 won, then load however much you need. The card works on every bus on the island.
The main hub is Jeju Intercity Bus Terminal (제주시외버스터미널), a ten-minute walk from the city centre. From here, Bus 201 runs along the north coast to Gimnyeong and Manjanggul Cave, Bus 281 cuts across the island to Seongsan, and the 600-series express buses race down to Seogwipo in about 50 minutes. Google Maps shows Jeju bus routes reliably, and the Kakao Maps app gives real-time arrival information in English.
Top Sights That Work Without a Car
The good news is that Jeju’s most iconic places are on or very near a bus route.
- Seongsan Ilchulbong (성산일출봉) — Bus 201 from Jeju Terminal takes about 70 minutes and drops you a five-minute walk from the ticket gate. Admission is 2,000 won. Climb to the crater rim for panoramic views of the eastern coast.
- Manjanggul Lava Tube (만장굴) — One of the world’s longest lava tubes, about 1 km of which is open to visitors. Bus 201 stops at Gimnyeong (김녕) village; from there it is a 15-minute walk. Entry is 4,000 won.
- Jeju Olle Trail — The 26-section coastal hiking network was built for walkers. Sections 1 and 2 (Seongsan area) are reachable by bus and connect to each other without any vehicle needed. Section 7 near Seogwipo is also bus-friendly.
- Seogwipo City (서귀포시) — Take express Bus 600 from Jeju City (3,000 won, ~50 min). From Seogwipo bus terminal you can walk to Cheonjiyeon Waterfall (천지연폭포, 2,000 won entry), Lee Jungseop Street, and the Jeju Olle Market on Saturdays.
- Jeju Folk Village (성읍민속마을) — Bus 표선행 (Pyoseon-bound) from the intercity terminal reaches Seongeup village. Free to walk the streets; the stone walls and traditional thatched houses make for an unhurried morning.
What to Skip (or Plan Very Carefully)
Hallasan National Park is doable by bus — the 1100 Highland bus (1100고지 버스) runs from both Jeju City and Seogwipo to the Eorimok and Yeongsil trailheads — but the schedule is limited to a handful of departures per day, so you must check times the night before and arrive early. Missing the last bus down means a very expensive taxi.
The western coast attractions — Hyeopjae Beach, Hallim Park, Biyangdo Island ferry — are reachable on Bus 202 from Jeju Terminal, but gaps between buses can be 40 to 60 minutes. This is fine if you plan to spend several hours at each place; it becomes frustrating if you want to hop between spots quickly.
The far southwest (Songaksan, Marado Island ferry terminal at Undeok Port) has infrequent buses and some require a transfer at Mosulpo. If these are high priority for you, consider renting a car for just one day (from around 50,000 won/day for a small manual), or joining a one-day group tour from Jeju City (typically 35,000–50,000 won including transport).
Practical Tips for a Car-Free Jeju Trip
- Base yourself in Jeju City for the first half of your trip, then move to Seogwipo for the second half. This cuts bus distances significantly and lets you walk to evening restaurants and cafes without worrying about transport.
- Download Kakao Maps before you land. Set the language to English and use the “Transit” routing mode — it shows walking segments and bus numbers in sequence.
- Use taxis for the last mile when needed. Jeju taxis start at 3,800 won and most drivers will accept Kakao Taxi (app-based), which lets you set destinations without speaking Korean.
- Rent an e-bike in areas where buses are sparse. Several rental shops near Seongsan and in Seogwipo charge around 10,000–15,000 won for a half-day and extend your range considerably.
- Allow buffer time. Buses in Jeju run every 20–30 minutes on popular routes and every 60 minutes on rural ones. Budget an extra 30 minutes for each main journey and you will rarely feel rushed.
Day Trip to Udo Island by Bus and Ferry
One excursion that fits a car-free itinerary particularly well is a Udo and Seongsan day trip, pairing the small volcanic island of Udo (우도) just off Jeju’s east coast with the Seongsan Ilchulbong area. Because the ferry terminal at Seongsan-ri is already on the Bus 201 route, you can combine a Seongsan Ilchulbong morning with an Udo afternoon without ever needing a rental car — something that surprises a lot of first-time visitors who assume island-hopping requires driving.
From Jeju Terminal, take Bus 201 to the Seongsan Port stop (about 75–80 minutes), then walk five minutes to the Udo ferry terminal. Ferries run roughly every 20–30 minutes in high season and every 30–40 minutes off-season, and the crossing takes about 15 minutes. A round-trip ticket costs around 8,500–13,000 won depending on the season and whether you bring a bicycle — prices can change, so check the posted board or Kakao Maps before you buy rather than relying on any figure you read online.
Once on Udo, there is no need for a car there either: the island is small enough (about 3.5km end to end) to cover on foot along the coastal path, though most visitors rent an electric scooter or bicycle at the port for roughly 15,000–25,000 won for a few hours — as of 2026, verify before visiting. This is the one place on the whole itinerary where a rental genuinely earns its cost, because Udo’s local minibus service is infrequent and the island’s best viewpoints (Seobin Baeksa white sand beach, the Udo lighthouse coastal trail, Haumokdong) are spread along a loop road that a scooter covers in under two hours.
Who should make time for this versus skipping it: if your Jeju trip is three days or fewer and you are already tight on time getting between Jeju City and Seogwipo by bus, Udo is worth cutting — it adds a minimum half-day including ferry queues. But if you have four or more days and enjoyed the slower pace of bus travel on the mainland, Udo rewards that same patience with far fewer crowds than Seongsan itself, especially if you take the first or second ferry of the morning before the day-tour buses from Jeju City arrive.
A tip most guides miss: the ferry ticket window at Seongsan only accepts cash or Korean cards for foreign passport holders in some booths, so carry at least 15,000 won in cash for the round trip and scooter deposit — card readers at the smaller booths occasionally reject foreign-issued cards even when the machine looks operational.
