Welcome to Jeju Island — Korea's Favourite Escape
If you ask any Korean where to go for a holiday, chances are the first word out of their mouth is Jeju. And honestly? They're right. Jeju Island sits about 90 kilometres south of the Korean mainland, and it feels like a completely different world — volcanic craters, black lava coastlines, tangerine orchards, and some of the freshest seafood you'll ever eat. For first-time visitors to Korea, Jeju is an absolute must-do, and this 2026 guide will walk you through everything you need to know before you go.
How to Get to Jeju Island
Getting to Jeju is easier than most people expect. You have two main options: fly or take a ferry.
By Plane (Recommended)
The fastest and most popular way is to fly. Jeju International Airport (CJU) receives direct flights from Seoul's Gimpo Airport (GMP) in about one hour, and from Incheon International Airport (ICN) in roughly 70–80 minutes. The Seoul–Jeju route is one of the busiest domestic air corridors in the world, so flights run very frequently throughout the day. Budget carriers like Jeju Air, T'way Air, and Air Busan often offer tickets for as low as ₩30,000–₩60,000 one way if you book in advance — though prices vary by season. Booking 4–6 weeks ahead is a smart move, especially for spring (April–May) and autumn (September–October), which are peak travel periods.
By Ferry
If you're travelling from Mokpo, Wando, or Busan on the mainland, you can take a ferry to Jeju. The journey takes anywhere from 1.5 to 13 hours depending on the departure port and vessel type. It's a more adventurous option and great if you're bringing a car, but for most first-timers, flying is the practical choice.
Getting Around Jeju Island
This is the part most first-timers underestimate. Jeju is not a city — it's a large island (roughly 73 km east to west), and public transport, while it exists, is limited compared to Seoul. Here's what you need to know:
Renting a Car (Highly Recommended)
Renting a car is by far the best way to explore Jeju at your own pace. Rental agencies are plentiful at the airport, and rates can start from around ₩40,000–₩70,000 per day for a compact car, depending on the season and vehicle type. An International Driving Permit (IDP) is required for most foreign visitors — check the requirements for your nationality before you travel. Driving in Jeju is generally relaxed compared to Seoul, and most major roads are well-signposted in English.
Public Buses
Jeju has an intercity bus network that connects major towns and tourist spots. The 360 and 365 circular bus routes are particularly useful for budget travellers, looping around the island's coast. However, buses can be infrequent in rural areas, and some key natural attractions require a walk from the nearest stop. If you're relying on buses, plan your itinerary carefully and download the Jeju Bus app or use Naver Maps for real-time schedules.
Taxis and Ride Apps
Taxis are available and metered, but fares can add up quickly if you're moving between distant spots. Kakao T (Korea's dominant ride-hailing app) works on Jeju and is a convenient backup option.
Top Attractions for First-Time Visitors
Jeju has no shortage of things to see, but here are the highlights that every first-timer should have on their radar.
Hallasan National Park
Hallasan is South Korea's highest mountain at 1,950 metres, and it sits right in the middle of Jeju. You don't have to be a serious hiker to enjoy it — there are multiple trails of varying difficulty. The Eorimok Trail is a popular, manageable option for casual hikers, while the Seongpanak Trail takes you all the way to the summit crater lake (Baengnokdam). Note that summit trails have strict cut-off times, so start early. Entrance to the national park is free, but trail access is regulated.
Seongsan Ilchulbong (Sunrise Peak)
This UNESCO World Heritage tuff cone rising dramatically from the sea is one of Jeju's most iconic images. Watching the sunrise from the top is a bucket-list experience — arrive before dawn and climb the steep but short trail (about 20–30 minutes). There is a small entrance fee (approximately ₩2,000–₩5,000 for adults, subject to change). The surrounding Seongsan village is also lovely for a morning walk and breakfast.
Manjanggul Lava Tube
One of the longest lava tubes in the world, Manjanggul is a fascinating underground cave system formed by ancient volcanic activity. Only about 1 km of the 7.4 km tube is open to the public, but it's well worth the visit. The cave stays cool year-round, so bring a light jacket even in summer. Entrance fees are modest (approximately ₩4,000–₩5,000 for adults).
Jeju Olle Trails
The Olle Trail network is a series of 26 coastal and inland walking routes that circle the island. Even completing just one section gives you an authentic feel for Jeju's landscapes — rocky shores, tangerine fields, traditional stone walls, and haenyeo (female divers) villages. Trail 1 near Seongsan is a favourite starting point for first-timers.
Jeju Folk Village Museum
For a cultural deep-dive, the Jeju Folk Village Museum in Seogwipo recreates traditional Jeju village life with over 100 authentic thatched-roof houses. It's one of the best places to understand how people lived on this island before modernisation. Entrance is approximately ₩11,000 for adults.
Cheonjeyeon and Cheonjiyeon Waterfalls
Jeju has several beautiful waterfalls, and these two are the most visited. Cheonjiyeon in Seogwipo is a single dramatic drop into a lush gorge, while Cheonjeyeon is a three-tiered cascade with a scenic bridge. Both are easily accessible and well-maintained.
What to Eat on Jeju Island
Jeju has a distinct food culture shaped by the sea and its volcanic soil. Don't leave without trying these:
- Heuk Dwaeji (Black Pork): Jeju's famous black pigs produce incredibly flavourful pork. Grilled black pork belly (heuk dwaeji samgyeopsal) is the island's signature dish. Head to the Black Pork Street (Heuk Dwaeji Geori) in Jeju City for a classic experience.
- Haenyeo Seafood: Jeju's legendary female divers (haenyeo) harvest fresh abalone, sea urchin, and conch. Look for haenyeo restaurants near coastal villages for the freshest catch.
- Galchi Jorim (Braised Cutlassfish): A spicy, savoury braised fish dish that's a Jeju staple. Rich, bold, and deeply satisfying.
- Hallabong Tangerines: Jeju's sweet, seedless tangerines are famous across Korea. Buy a bag from a roadside stall — they're inexpensive and delicious.
- Omegi Tteok: A traditional Jeju rice cake made with millet, often coated in red bean paste. A perfect snack or souvenir.
Practical Tips for First-Time Visitors
Best Time to Visit
Spring (April–May) and Autumn (September–October) are the most popular seasons — mild weather, beautiful scenery, and manageable crowds. Summer (July–August) is hot and humid with beach crowds and higher prices. Winter (December–February) is quieter and cheaper, and Hallasan often gets snow, which is magical — but some hiking trails may be closed.
How Many Days Do You Need?
A minimum of 3 full days is recommended to cover the highlights without rushing. Four to five days is ideal if you want to hike Hallasan, explore the coast, and enjoy the food scene at a relaxed pace.
Money and Payments
Most hotels, restaurants, and shops in Jeju accept credit and debit cards. However, some smaller local eateries, market stalls, and rural attractions are cash-only, so keep some Korean Won (₩) on hand. ATMs are widely available in Jeju City and Seogwipo.
Language
English signage is reasonably good at major tourist sites, and many hotels have English-speaking staff. Away from tourist zones, English is less common — having Naver Papago (translation app) or Google Translate on your phone is genuinely useful.
Common Mistakes First-Timers Make
- Not renting a car: Trying to see Jeju purely by bus is frustrating and time-consuming. If you can drive, rent a car.
- Underestimating distances: Jeju looks small on a map but driving from one end to the other takes over an hour. Plan your daily routes geographically to avoid backtracking.
- Skipping the east coast: Many visitors cluster around Jeju City and miss the stunning east coast around Seongsan and Udo Island. Don't make that mistake.
- Ignoring weather forecasts: Jeju's weather can change quickly, especially in the mountains. Check forecasts daily and have a backup plan for rainy days (caves, museums, and indoor markets are great alternatives).
- Booking accommodation too late: During peak seasons, good guesthouses and pensions fill up fast. Book at least 4–6 weeks in advance.
Etiquette Tips for Jeju
Jeju people are generally warm and welcoming to foreign visitors. A few cultural notes to keep in mind:
- When visiting haenyeo villages or watching divers work, observe quietly and respectfully — this is their livelihood and cultural heritage, not a performance.
- Remove your shoes when entering traditional guesthouses (minbak) or some local restaurants where floor seating is used.
- Littering on trails or beaches is taken seriously — always carry your rubbish out.
- At Hallasan and other national park trails, stick to marked paths. Going off-trail is prohibited and can result in fines.
Frequently Asked Questions (FAQ)
Do I need a visa to visit Jeju Island?
Jeju operates a visa-free entry policy for many nationalities, separate from mainland South Korea's visa rules. Citizens of many countries can enter Jeju without a visa for short stays. However, policies can change, so always verify the current requirements with the Korean embassy or consulate for your country before travelling.
Is Jeju Island expensive?
Jeju can suit a range of budgets. Budget travellers using guesthouses and local eateries can get by on around ₩80,000–₩120,000 per day. Mid-range travellers staying in comfortable hotels and dining at sit-down restaurants should budget around ₩150,000–₩250,000 per day, excluding car rental.
Can I visit Udo Island as a day trip from Jeju?
Absolutely. Udo Island is a small, charming island just off the east coast of Jeju, accessible by ferry from Seongsan Port (about 15 minutes). It's famous for its peanut ice cream, turquoise waters, and cycling paths. A half-day or full-day trip is very doable.
Is Jeju Island safe for solo travellers?
Yes, Jeju is considered very safe for solo travellers, including solo female travellers. South Korea consistently ranks among the safest countries in the world for tourists. Standard travel precautions apply, but you're unlikely to encounter serious issues.
What's the best app for navigating Jeju?
Naver Maps is the most accurate navigation app for Korea and works excellently on Jeju, including for driving directions. Kakao Maps is another solid option. Google Maps has improved in Korea but can still be less reliable for detailed local routing.
