Why Visit Jeju Island?

Often called the "Hawaii of Korea," Jeju (제주도) sits off the southern tip of the peninsula and feels completely different from the fast pace of Seoul. Black lava rock coastlines, lush crater trails, crystal-clear waters, and a laid-back pace make it Korea's ultimate nature escape.

• UNESCO Triple Crown: The only place in the world with three UNESCO designations — Natural Heritage, Biosphere Reserve, and Geopark
• Year-round destination: Cherry blossoms in spring, beaches in summer, golden foliage in autumn, snow on Hallasan in winter
• Easy to reach: 1 hour by plane from Seoul
• Visa-free for many nationalities under Jeju's separate visa exemption policy

👉 Best for: Anyone wanting Korean nature without Seoul crowds. First-time Korea visitors who want variety beyond the capital.

How to Get to Jeju Island

By Air (Recommended)

Flying is by far the easiest option. Jeju International Airport (CJU) is Korea's busiest domestic airport with flights every 20–30 minutes from Seoul.

• From Seoul Gimpo or Incheon: ~1 hour flight
• Airlines: Korean Air, Asiana, Jeju Air, T'way Air, Jin Air
• Booking tip: Reserve 2–4 weeks ahead for best fares — prices spike during school holidays and Chuseok

By Ferry

• From Mokpo: 4.5 hours (speedboat) or 9 hours (regular ferry)
• From Busan: 11–12 hours overnight ferry
• Great option if you want to bring a car or enjoy the sea crossing

When to Visit Jeju

Best time: Late September to early November — perfect hiking weather, fewer tourists, stunning foliage.

👉 Skip summer if you hate crowds — July and August fill up fast and accommodation prices double.

Top Things to Do in Jeju Island

1. Hike Hallasan National Park

Hallasan (1,950m) is South Korea's tallest mountain, sitting at Jeju's center. The hike to the crater lake is one of Korea's most iconic outdoor experiences.

• Seongpanak Trail: 9.6km, 4–5 hours up — most popular full-summit route
• Gwaneum-sa Trail: 8.7km, steeper and more dramatic views
• Eorimok Trail: Shorter option to a mid-mountain viewpoint — good for families
• Key rule: Trails close 2–3 hours before sunset — start no later than 9am

👉 Best for: Serious hikers and bucket-list experiences. Allow a full day.
👉 Skip if: Short on time — Seongsan gives equally dramatic scenery in 2 hours.

2. Seongsan Ilchulbong (Sunrise Peak)

This dramatic tuff cone rising from the sea is Jeju's most photographed landmark — 99 rocky peaks forming a natural crown around a massive crater. A UNESCO World Heritage Site.

• Sunrise viewing: Gates open at 7am — arrive 30 minutes early for a good spot
• Haenyeo diving shows: Watch Jeju's famous female free divers at the base daily (1:30pm, 2:30pm, 3:30pm)
• Entrance fee: ₩5,000 adults
• The climb takes just 20 minutes — far easier than Hallasan

👉 Must-see highlight. If you do only one thing in Jeju, this is it.
👉 Best for first-time visitors — accessible, dramatic, and uniquely Jeju.

3. Hyeopjae Beach

The best beach on Jeju — emerald-green water, fine white sand, and a pine forest backdrop. Far cleaner and less crowded than beaches near Jeju City.

• Swimming season: Late June through September
• Nearby: Bichigul Lava Tube and Hallim Park are a 5-minute drive away
• Calm, shallow water — ideal for families with young children

👉 Best beach in Jeju. Skip the touristy beaches near Jeju City and head straight here.

4. Manjanggul Lava Tube

One of the world's longest and best-preserved lava tubes — over 13km total with 1km open to visitors. The 7.6m lava column inside is the world's largest.

• Temperature: A constant 11°C inside — bring a light jacket even in summer
• Entrance fee: ₩4,000 adults
• Wear closed-toe shoes; the ground is uneven lava rock

👉 Best for: Families and geology enthusiasts. Pairs perfectly with Seongsan — both on the east side.
👉 Skip if: Claustrophobic. Some sections are low and narrow.

5. Haenyeo Culture

Jeju's haenyeo (해녀) — women who free dive for seafood without oxygen tanks — are a UNESCO Intangible Cultural Heritage. Many divers are in their 60s, 70s, and 80s and still work daily.

• Haenyeo Museum: Gujwa-eup, free entry — fascinating exhibit on their history and traditions
• Watch live: Diving shows at Seongsan Ilchulbong base (1:30pm, 2:30pm, 3:30pm)
• Try the seafood: Fresh abalone (전복), sea urchin, and conch at coastal restaurants — the freshest seafood in Korea

👉 Most authentic Jeju experience. This tradition exists nowhere else in the world.

6. Jeju's Unique Food Scene

Jeju has its own distinct food culture. These are the must-tries:

• Heuk dwaeji (black pork): Jeju's famous black-skinned pork — richer and more flavorful than regular pork belly. Must-try on Heuk Dwaeji Street in Jeju City
• Jeonbokjuk: Abalone porridge — silky, deeply satisfying, especially as a morning meal
• Hallabong: Jeju's signature mandarin orange — sweeter than anything on the mainland (November–March)
• Okdom-gui: Grilled red tilefish, a coastal Jeju specialty

For Korean food basics before you land, see our guide to Korean food for first-time visitors and Korean street food guide.

👉 Don't miss black pork. It's genuinely different from mainland samgyeopsal — a must at least once.

Where to Stay in Jeju

Choosing the right base makes a big difference to your Jeju experience:

👉 Best area for first-time visitors → Seogwipo
Central position for east and west day trips, stunning coastal scenery, and far less crowded than Jeju City.

Recommended properties:

• Luxury: The Shilla Jeju, Lotte Hotel Jeju (Seogwipo)
• Mid-range: Ramada by Wyndham Jeju, Landing Hotel
• Budget: Local guesthouses (게스트하우스) from ₩30,000/night

Getting Around Jeju

Renting a car is by far the best option — public transportation is limited and attractions are spread across the island.

• Cost: ₩40,000–80,000/day for a standard car
• International license: Required (IDP + your home country license)
• Book in advance during peak seasons — cars sell out fast
• Navigation: Google Maps and Naver Maps both work well in Jeju

No car? A guided tour with hotel pickup is the next best thing — all transport handled, no navigation stress.

Jeju Olle Trail: A 437km coastal walking route divided into 26 sections — the most rewarding slow-travel experience if you have a week or more.

Tips for Visiting Jeju

• Book early: Cherry blossom season (late March–April) and summer sell out weeks in advance
• Weather changes fast: Pack a rain jacket even in summer — Jeju gets sudden showers
• Hallasan prep: No vendors on upper trails — bring snacks and at least 1.5L of water
• Jeju Pass card: Bundles many attractions — check if it suits your itinerary before buying
• Respect haenyeo: They are elderly and working — keep a respectful distance when watching
• Packing: Check our Korea packing guide for season-appropriate clothing
• Etiquette: Our Korean etiquette guide covers what to know before you go

Want Your Own Pace? Go Private

Rather skip the group and explore on your own schedule? A private car tour lets you customize every stop — perfect for couples, families, or anyone who wants to linger longer at the spots they love.
