Jeju Island

Jeju — A Different Country Inside Korea

Jeju is Korean but not quite Korea. A volcanic island, the warmest and windiest part of the country, with a dialect almost a separate language. For foreign travelers, Jeju is "the resort island you save for the end of the trip." Nature, food, and drives — completely different in feel from the mainland.

What it is

Korea's southernmost volcanic island. About three times the size of Seoul. Hallasan (1,947 m) sits in the middle, with cliffs, beaches, and harbors lining the coast. UNESCO World Natural Heritage. Two main bases: Jeju City (airport, downtown, Dongmun Market) in the north and Seogwipo (coastal scenery, Olle trails) in the south.

Must-visit spots

• 🌋 Hallasan — Korea's highest peak. Has its own page. The Seongpanak and Gwaneumsa courses require advance reservation; Yeongsil and Eorimok are easier.
• 🌅 Seongsan Ilchulbong — a 30-minute walk around a crater rim. Famous sunrise spot.
• 🏝 Udo Island — 15-minute ferry from Seongsan. Loop it by bike or electric cart (3 hours). Peanut ice cream is the local thing.
• 🕳 Manjanggul Cave — lava tube. 12 °C even in midsummer — a great heat escape.
• 🌊 Hyeopjae / Hamdeok Beach — emerald water. Hyeopjae has the Biyangdo Island view.
• ☕ Cafés (an insane density) — every hour along the coastal road has a notable café. Jeju is café heaven.
• 🌳 Saryeoni Forest Path / Bijarim Forest — easy forest walks. A good alternative if Hallasan feels too much.
• 🪨 Daepo Columnar Joints — basalt cliff pillars. A photo spot.

Food — different from the mainland

• Black-pig BBQ — Jeju's signature. Notably thick cuts. Try Donsadon or the Black Pig Street in Yeon-dong / Jungmun.
• Galchi stew / grilled hairtail — a whole hairtail, served big. Restaurants in Dongmun Market.
• Gogi-guksu (pork-bone noodle soup) — Jeju's home dish. Samdae Guksu Hoegwan (downtown) is a classic.
• Abalone porridge / abalone dishes — a product of the haenyeo (women divers) culture. Pricier.
• Omegi-tteok — millet and red bean. A market snack.
• Hallabong / mandarins — winter season, often paired with farm visits.

Getting there — flying is basically the only way

• Air: 1 hour from Gimpo, Incheon, Busan, etc. The world's busiest air route (Gimpo-Jeju). Prices swing a lot — book early.
• Ferry: from Mokpo, Wando, Busan, etc. Long (5–12 hours), not recommended.
• Airport → downtown: city bus (e.g., 600 series) or taxi (around 10,000 won).

Getting around — a car is essentially required

Public transit is weak. City buses exist but stringing sights together by bus eats your day. Options:

• Rental car — the standard. International driving permit required. About 50,000–100,000 won/day.
• Taxi / KakaoT — fine for short hops, expensive all day.
• Bus + walking — possible, but you'll spend half the day waiting. Not recommended.
• Group tours — many English-speaking day tours. The right call if you don't want to drive.

Suggested itineraries

• 2 nights, 3 days — Day 1: downtown + Dongmun Market + Hyeopjae / Day 2: Seongsan + Udo / Day 3: Hallasan or Saryeoni Forest
• 3 nights, 4 days — add Seogwipo (columnar joints, Cheonjiyeon, cafés)
• 5+ days — try the Hallasan summit + one Olle trail segment

Season by season

• 🌸 Spring (Mar–May) — canola flowers (late March), cherry blossoms, Hallasan azaleas. Popular season.
• ☀️ Summer — swimming and haenyeo season. Watch out for monsoon rains and typhoons.
• 🍁 Autumn (Oct–Nov) — the most pleasant. Hallasan foliage + silver grass. Top-recommended season.
• ❄️ Winter — Hallasan snowscapes and citrus. Warmer than the mainland, but the wind is strong.

Honest tips

• Without a rental car, half your trip is travel time. No license? Take a taxi day tour.
• Air + hotel packages are often cheaper than booking separately. Compare prices.
• Black-pig restaurants can be touristy and pricey. Search for locals' recommendations.
• The Hallasan summit course has daily entry limits + advance reservation. Check the official Hallasan National Park site about a month before.
• Wind is no joke. Use a hat strap and pack a poncho instead of an umbrella.
