What should I know before visiting Jeju Island?

Direct answer

Jeju Island (Jeju-do) is a popular South Korean island known for volcanic landscapes, beaches, hiking, and unique local culture. Plan for entry, transport, weather, and local customs to make the most of a visit.

Visa / entry requirements

• Nationals of many countries can enter South Korea visa-free for short stays (varies by nationality). Check the Korean embassy/consulate or Korea Visa Portal for up-to-date rules.
• All visitors need a valid passport with at least 6 months validity recommended.
• Some travelers require an Electronic Travel Authorization (K-ETA) — verify before travel and apply online if needed.
• No separate visa for Jeju: it follows South Korea’s entry rules.

Best time to visit

• Spring (April–June): Cherry blossoms, mild temperatures, fewer rainy days — excellent for hiking and sightseeing.
• Autumn (September–November): Clear skies, pleasant temperatures, colorful foliage — arguably the best time.
• Summer (July–August): Warm to hot, humid, peak tourist season, beach activities; expect more rain and typhoon risk in late summer.
• Winter (December–February): Cooler with occasional snow on Hallasan; fewer tourists and lower prices.

Safety tips

• Jeju is generally very safe; petty theft is uncommon.
• Watch for strong coastal currents and obey beach signage and lifeguards; some beaches have dangerous rip currents.
• If hiking Hallasan or other trails, check trail status/weather, carry water, proper footwear, and a map/GPS; trails can be steep and foggy.
• In summer, monitor weather/typhoon warnings and flight/ferry updates.
• Emergency numbers: 112 (police), 119 (fire/ambulance). English support is limited but available in tourist centers and some hotels.

Local customs and etiquette

• Bowing or a slight nod is common when greeting; a handshake is fine with Westerners. Use both hands when giving/receiving business cards or gifts.
• Remove shoes when entering many traditional accommodations, guesthouses, and some restaurants/homes.
• Public displays of affection are generally acceptable but keep it modest in rural areas.
• Tipping is not customary; excellent service is usually included. Small tips may be accepted in tourist settings but are not expected.

Currency and money

• Currency: South Korean won (KRW). Cash is widely used; cards (Visa/Mastercard/Amex) are accepted in most hotels, restaurants, and stores.
• ATMs: Readily available in Jeju City and major tourist spots; use ATMs that accept international cards. Some local/unmanned ATMs may not accept foreign cards.
• Credit cards may not work in small rural shops or markets—carry some cash.

Transportation on Jeju

• By air/ferry: Most visitors arrive by plane to Jeju International Airport (CJU) — many domestic and international flights. Ferries connect from mainland ports (Busan, Mokpo, etc.).
• Public buses: Extensive and cheap network linking major sites; schedules can be slow and infrequent for remote spots.
• Car rental: Highly recommended for flexibility; roads are good and signage often in English. International driving permit (IDP) plus home license may be required depending on nationality—check rental agency rules.
• Taxis: Widely available and affordable for short trips; long-distance fares can add up. Some drivers have limited English—use addresses or phone numbers for destinations.
• Tours: Day tours and guided excursions are plentiful and convenient for hikers, boats, and cultural sites.

Must-know tips & local insights

• Must-see: Hallasan National Park (summit/hiking), Seongsan Ilchulbong (Sunrise Peak), Manjanggul Lava Tube, Jeju Olle Trails, Jeju Folk Village, Cheonjiyeon/Cheonjeyeon waterfalls.
• Food: Try black pork (heuk-dwaeji), abalone dishes, fresh seafood, and Jeju tangerines.
• Coffee culture: Jeju has many scenic cafes—great for views and local roasters.
• Language: Korean is primary. English signage exists in tourist areas; having Korean phrases or a translation app helps in rural areas.
• Connectivity: Buy a Korean SIM or portable Wi-Fi at the airport for data and navigation.
• Environmental respect: Jeju has unique ecosystems—follow trail rules, don’t remove volcanic rocks/shells, and avoid littering.
• Shopping: Local specialties include tangerine products, sea salt, green tea, and Jeju cosmetics. Duty-free shopping is available for international travelers.
• Time to allocate: 3–5 days for major highlights; a week if you want to hike, explore remote beaches, and relax.

Practical checklist

• Check visa/K-ETA requirements and passport validity.
• Book transport and accommodation in peak seasons early.
• Rent a car or plan bus routes; download local transit apps and maps.
• Pack layered clothing, sun protection, and good hiking shoes.
• Get a SIM card or Wi-Fi device at the airport.
