Jeju Travel Guide 2026: Know Before You Go
Jeju is South Korea’s volcanic island, not a separate country, and it genuinely is not tropical, expect a real winter with Hallasan snow even though palm trees line the beaches. Land at Jeju International Airport, rent a car (bring a physical International Driving Permit from home, Korea does not issue one on arrival), and budget roughly 78,000-105,000 KRW (about $52-70) a day for a mid-range trip. Currency is the Korean won (KRW, ~1,490 to $1), tipping is not expected anywhere on the island, and if summiting Hallasan matters to you, book that reservation before you fly, not after.

Getting to Jeju Island (and why the flight is the easy part)
Jeju International Airport (CJU) sits about 3km from downtown Jeju City, and the Gimpo-Jeju air route from Seoul is the busiest passenger air route on the planet, something like 13 million passengers a year on flights running every few minutes at peak times, with nine-plus airlines competing for your seat. The flight itself is barely an hour. Ferries reach Jeju too, mainly from Wando (about 2h40, the busiest link), Mokpo (about 4h30), or Nokdong (about 3h30, often the cheapest), all landing at Jeju Port; ferries from Busan and Incheon have been discontinued, so don’t build a route through either.
From the airport, a taxi into Jeju City runs about 15 minutes for roughly 9,000 KRW ($6); Seogwipo is 50-60 minutes and 40,000-60,000 KRW ($25-40) by taxi. Arriving during Korean summer break, Chuseok, or Lunar New Year? Book your rental car pickup before you land, the airport counters back up hard at those times.
Getting around Jeju: the IDP rule that trips people up
Rent a car. Jeju’s sights ring a roughly 260km coastal loop plus the interior around Hallasan, and public transit, while it works, turns a multi-stop day into a slow one. The catch: foreign visitors need a physical, book-type International Driving Permit obtained in their home country before arrival, Korea does not issue IDPs on arrival and won’t accept a digital copy or a foreign license alone. Korea also does not accept IDPs issued by mainland China, Taiwan, or Indonesia, so travelers from those places generally can’t rent and self-drive here, confirm the current list via visitjeju.net before you book. Expect to pay roughly 45,000-150,000 KRW (~$30-100) a day for a compact rental, more in summer and around Korean holidays.
Do you actually need a car on Jeju? For anything beyond a single day around Jeju City, yes. Buses run reliably (base fare ~1,150-1,200 KRW with a T-money card) and a tourist shuttle loops the east and west sightseeing circuits for a flat day pass, but both add real time to a multi-sight day. A scooter is a workable alternative for short stays without an IDP, though it’s also the single most commonly cited source of tourist injury on the island, unfamiliar rural roads and fast local traffic catch people out.
Where to stay: Jeju City or Seogwipo
Jeju City (north) is the default first-timer base: bigger, airport-adjacent (10-20 minutes), the widest hotel and food choice, and home to Black Pork Street and Dongmun Market. Seogwipo (south) runs a few degrees warmer year-round thanks to Hallasan’s rain-shadow effect, sits walking distance from the main waterfalls and the Olle Market, and is often cheaper per night than an equivalent Jeju City room. Base in Jeju City for a short trip; split the stay across both if you’re here 4 nights or more. Check Seogwipo rates on Booking.com if you’re adding a south-coast night.
What to eat in Jeju: black pork, haenyeo seafood, and hallabong
Heuk-dwaeji (Jeju black pork) is the dish to build a meal around, a native black pig grilled tableside, richer than standard Korean pork belly. Most black-pork restaurants sell by the geun (about 600g), so a solo diner often has to order the full minimum unless a lunch set is offered; budget roughly 20,000-25,000 KRW (~$13-17) a person. Black Pork Street in Jeju City is the concentrated, competing-restaurant version of this, and it’s the one meal on this island genuinely worth planning a whole evening around. Fresh abalone and other haenyeo-caught seafood show up raw, grilled, or as jeonbok-juk (abalone porridge, 15,000 KRW/$10), and hallabong, Jeju’s seedless mandarin, is the one food souvenir worth buying fresh from a roadside stall rather than a supermarket.
When to visit Jeju in 2026
Spring (late March-April) brings the island’s best photo op: Noksan-ro road runs pink cherry blossoms and yellow canola flowers at the same time, with 2026 bloom forecast around March 25 and a best-viewing window of roughly March 28-April 5 (check a live forecast closer to your dates, blossom timing shifts every year). Autumn (October-November) is widely considered the best Hallasan and Olle-trail hiking season, cooler, drier, and past typhoon risk. Summer (June-August) means beach weather and peak domestic Korean crowds layered on international tourism, plus a real typhoon risk from July through September that can ground flights and shut Hallasan on short notice. Winter is mild at the coast but genuinely windy, and Hallasan’s summit gets real snow and sub-zero cold, not the mild island winter the beach photos suggest.
Is Jeju tropical? No, despite the palm trees and turquoise water at beaches like Hyeopjae and Hamdeok. Jeju sits in a temperate-to-humid-subtropical transition zone with a genuine winter: coastal temperatures dip toward freezing, and Hallasan’s summit sees actual snow and sub-zero cold. Pack for four real seasons, not a year-round beach trip.
Hallasan: the reservation you can’t wing
Hallasan (1,947m) is South Korea’s highest peak and the dormant shield volcano the whole island formed around, with the Baengnokdam crater lake sitting at its summit. Reaching the actual crater rim, via the Seongpanak or Gwaneumsa trails, needs a free advance reservation at visithalla.jeju.go.kr , capped at roughly 1,000 hikers a day on Seongpanak and 500 on Gwaneumsa, released monthly and known to fill within minutes in peak season. Miss the window and four other trails, Eorimok, Yeongsil, Donnaeko, and others, reach high viewpoints without the reservation, a legitimate backup, not a consolation prize.
Do you need a reservation to hike Hallasan? Usually, for the true summit trails, yes, but the park has periodically suspended the requirement for limited seasonal windows while keeping the same descent cutoffs, so don’t assume either “always” or “never.” Check visithalla.jeju.go.kr or the Hallasan National Park English site for the live rule before you build a day around it. Browse a Hallasan trekking-transfer tour on Viator if you’d rather not self-drive to the trailhead.
Jeju FAQ
Is Manjanggul lava tube open right now? It reopened 30 May 2026 after a rockfall closure that ran from December 2023, with new safety upgrades. Entry runs about 4,000 KRW (~$3) adult. Confirm it’s still open before you build a day around it, a reopening this recent can still see short follow-up closures.
Do I need to tip in Jeju? No. Tipping is not customary anywhere in South Korea, including Jeju, and service charges aren’t added at ordinary restaurants.
Is Jeju safe? Genuinely, yes, one of South Korea’s safest regions for violent crime. The real risks are environmental: typhoons (July-September), strong sun on exposed coastal walks, sudden Hallasan weather, and unfamiliar-road driving, not crime.
Once the essentials are sorted, the places worth building a day around and the 2-day through 7-day itineraries turn this into an actual schedule. Get an east coast day tour on GetYourGuide if you land without a car and want Seongsan, Manjanggul, and the Haenyeo Museum covered in one booked day.
