1. 🛂 Entry Prep — K-ETA and the e-Arrival Card

Check your entry requirements first — they depend entirely on your nationality, so confirm before buying flights.

• K-ETA (Korea Electronic Travel Authorization): An online travel authorization normally required for visa-free travelers. However, passport holders from many countries — including the US, Canada, Japan, the UK, and Australia — are temporarily exempt through December 31, 2026, so they can enter without a K-ETA during this period.

  • If you're not exempt, apply on the official government site www.k-eta.go.kr or the official app. Screening usually takes up to 72 hours but can take longer when applications surge, so apply well in advance — not right before departure. There's a fee, and approval is generally valid for 3 years from the approval date (or until your passport expires, whichever comes first; check the official site for conditions).

  • ⚠️ Search results are full of unofficial agency sites that look official and charge several times the real fee. Use only the official link above, and check that the address in your browser ends with the government domain (.go.kr).

• e-Arrival Card (electronic arrival declaration): A system that lets you fill out your arrival card online before entering Korea (in service since February 2025). You can submit it for free from 3 days before arrival (Korea time) on the official government site www.e-arrivalcard.go.kr — if you submit it electronically, you don't need to fill out a paper arrival card.

  • You'll enter your name, passport number, flight number, and accommodation address in Korea, so keep your booking confirmation handy.

  • Not everyone needs to submit one: travelers holding a valid K-ETA, registered foreign residents, and flight crew are exempt from the arrival card requirement. Check the official guidance to see whether you need to submit.

  • Traveling with family? Check the official guidance on whether each person submits individually or a group submission is possible.

• Passport validity: In principle, Korea requires your passport to be valid for the duration of your stay. However, your home country, transit countries, or airline may apply separate validity rules (e.g., 6 months) — confirm before departure.

• Visa: If your nationality isn't visa-free, obtain a visa in advance from your local Korean embassy or consulate. Also check your visa-free stay limit (usually 30–90 days, varies by nationality).

• Customs & quarantine: Declare items if required (large amounts of cash, goods exceeding duty-free limits, etc.). Bringing in meat and fruit is strictly restricted — watch out even for snacks like beef jerky.

2. 🎒 Packing — Korea-Specific Items to Bring

Beyond the basics, a few items matter especially for Korea.

• Power adapter: Korea uses 220V with Type C/F (European round two-pin) outlets. If you're coming from a 110V country (US, Japan, etc.), you'll need an adapter. Most modern electronics (laptop and phone chargers) accept 100–240V, but check the voltage on hair dryers and curling irons. An adapter with multiple outlets is handy for charging several devices at once.

• Clothing by season:

  • Spring (Mar–May): Large day-night temperature swings — dress in layers. A mask helps on days with fine dust or yellow dust.

  • Summer (Jun–Aug): Hot and very humid (feels like 30–35°C). Late June–July is monsoon season — bring an umbrella and water-resistant shoes. Indoor air conditioning is strong, so pack a light layer too.

  • Autumn (Sep–Nov): The best travel season. Clear and cool, but chilly mornings and evenings call for a light jacket.

  • Winter (Dec–Feb): Temperatures can drop below −10°C. Bring a heavy padded coat, gloves, and a hat — convenience-store hand warmers (hot packs) help a lot.

• Medications: Bring more prescription medication than your trip requires, and carry an English prescription or a note of the drug (ingredient) names. Pharmacies are everywhere, but prescription drugs require a doctor's prescription, and some ingredients (certain cold medicines, ADHD medications, etc.) may have import restrictions — check in advance for large quantities. Basic fever reducers and digestive aids are sold at convenience stores.

• Comfortable shoes: Many travelers walk 20,000+ steps a day in Seoul, with plenty of hills and stairs (especially subway transfers). Some hanok, floor-seating restaurants, and cafés require removing shoes — slip-ons plus clean socks are a good combo.

• Other: Guesthouses and hanok stays may not provide towels or toiletries, or may charge for them. Check what's included when booking.

3. 📱 Phone Setup — The Right Apps Are Half the Trip

Due to map data export restrictions, Google Maps' walking and driving navigation has been limited in Korea. In February 2026, the government conditionally approved the export of high-precision map data, so features may improve — but support can keep changing. For now, installing NAVER Map is your safest bet. Set up the apps below before departure, and register accounts and cards where possible.

• NAVER Map: The most recommended map app for foreign visitors. It supports Korean, English, Japanese, and Simplified Chinese, with transit and walking directions, real-time bus arrivals, and store hours and reviews. Save your must-visit spots as favorites to plan routes easily.

• KakaoMap: A map app widely used by locals, with an English interface. Great as a companion to NAVER Map.

• Papago: Naver's Korean-specialized translation app. Its camera translation for menus and signs and its voice conversation mode are especially useful. Download the offline pack to translate without internet.

• k.ride / Kakao T: For foreign travelers, k.ride — Kakao Mobility's taxi-hailing app for international visitors — is the easy choice. It supports English, Japanese, and Chinese, plus Google/Apple login and foreign-issued credit cards. Kakao T, Korea's main taxi app, also works — you enter your destination in advance, so no Korean is needed; check payment options in the app.

• Subway apps: NAVER Map is enough, but a subway-focused app (e.g., Subway Korea) is handy for transfers and last-train times.

• Getting online — 3 options:

  • eSIM (recommended): Buy online before departure and activate by QR code — no airport lines, and your original SIM stays in place. Confirm your phone supports eSIM and is carrier-unlocked.

  • Physical SIM: Available at Incheon Airport carrier booths and convenience stores. Counters get crowded in peak season, so booking online for airport pickup is smoother.

  • Pocket Wi-Fi: Good for groups or connecting laptops/tablets. Requires daily charging and must be returned.

  • Prices and data terms vary by provider — compare before choosing. Korea also has excellent free Wi-Fi in cafés, subways, and public spaces.

4. 💳 Money & Payment — Card-First, a Little Cash

Korea has one of the world's highest card payment rates, but there are still moments when you need cash.

• Credit cards: Visa and Mastercard work at most restaurants, cafés, convenience stores, and shops. American Express and JCB are accepted in fewer places. Bring a card with low foreign transaction fees, and choose to pay in Korean won (KRW) at checkout to avoid dynamic currency conversion (DCC) fees.

• Where you'll need cash: Traditional markets, street stalls, some small restaurants, and T-money top-ups (many machines are cash-only). Around 100,000–200,000 KRW as a reserve is often enough (for reference).

• Currency exchange: Airport rates tend to be less favorable — exchange a small amount there and use private exchange offices downtown (e.g., Myeongdong) or banks. ATMs marked "Global ATM" accept foreign cards (fees vary by card issuer and machine).

• Foreigner-focused cards (e.g., WOWPASS): Prepaid cards that convert your foreign currency to won and double as T-money. Issued at kiosks in major stations and tourist areas (check official terms and fees).

• Mobile pay: Apple Pay acceptance is growing but not universal; Samsung Pay, Naver Pay, and Kakao Pay generally require a Korean account or card. Check with your card issuer about support for foreign-issued cards.

• Tax refund: Spend above a minimum amount at stores marked "Tax Free" and you can get the VAT refunded — either instantly at the store or at airport kiosks/counters. Either way, you must show your passport, so carry it when shopping.

5. 🚇 Transit — One T-money Card Is All You Need

• T-money card: A rechargeable transit card sold at convenience stores (CU, GS25, 7-Eleven) and subway stations for a few thousand won (for reference). It works on subways, buses, and taxis, and even for convenience-store purchases.

  • Top up at convenience-store counters or station machines — often cash only.

  • Transfer discounts between subway and bus apply automatically, saving a lot. Tap in and out on buses.

  • Remaining balance can be refunded at convenience stores (small fee applies).

• Riding a lot in Seoul? Beyond T-money, there's the Climate Card Short-Term Pass — unlimited Seoul subway and bus rides for 1, 2, 3, 5, or 7 days. Compare which is cheaper for your itinerary (check official guidance for coverage and terms).

• From Incheon Airport to downtown:

  • AREX All-Stop Train: To Seoul Station in about 59 min from Terminal 1, about 66 min from Terminal 2. The cheapest option, payable with T-money.

  • AREX Express Train: Non-stop between Incheon Airport and Seoul Station — about 43 min from T1, about 51 min from T2. Reserved seats and luggage space make it comfortable with heavy bags (separate fare, for reference).

  • Airport limousine bus: Direct to major hotels and districts — great with lots of luggage or if your hotel is far from a station.

  • Taxi: Fares to downtown Seoul add up, tolls included. Consider it for late-night arrivals or groups of 3–4. Use official taxi stands and avoid touts.

  • 👉 For a detailed comparison of times, fares, and best-fit scenarios, see the post 🚆 인천공항에서 서울 도심까지, 가장 쉽고 간단하게 가는 법 (AREX·버스·택시 비교).

• Subway: Seoul's subway has English signage at every station and in every car, with reasonable base fares (for reference). Note that service ends around midnight — check last-train times on NAVER Map. Rush hours (8–9 am, 6–7 pm) are very crowded.

• Bus: Dense network, payable with T-money. Real-time arrivals show on stop displays and map apps. Press the bell before your stop.

• Taxi: Metered fares; hailing via k.ride or Kakao T is easiest. Regular, deluxe, and van taxis are available; late-night surcharges apply.

• Intercity travel (KTX): The high-speed KTX makes Seoul–Busan about 2.5 hours and Seoul–Gangneung about 2 hours. The KORAIL PASS, an unlimited rail pass for foreign visitors, may pay off if you take 2+ intercity trips. Weekend and holiday tickets sell out fast — book ahead on the KORAIL site or app.

6. 🏨 Accommodation — Location Is Everything

• Choosing a neighborhood (Seoul):

  • Myeongdong: Convenient for shopping, currency exchange, and airport bus routes — a safe pick for first-timers.

  • Hongdae: Young vibe with cafés, clubs, and busking. Direct AREX access makes airport trips the easiest.

  • Gangnam: Trendy shopping and dining, but far from the palaces and traditional sights.

  • Jongno / Insadong: Near Gyeongbokgung and traditional culture — great if you want a quieter stay.

• Types of stay: Beyond hotels, options include guesthouses (budget, social), hanok stays (traditional experience), and residences (with kitchens). Spending a night at a jjimjilbang (Korean sauna) is an experience, but not recommended as a comfortable lodging substitute.

• When to book: Cherry blossom season (late March–early April), autumn foliage (Oct–Nov), and major holidays (Seollal, Chuseok) fill up fast — book at least 1–2 months ahead.

• Check-in notes: Check-in is usually around 3 pm, checkout around 11 am. Arriving early? Use luggage storage services or station lockers. Confirm from photos whether your room is ondol-style (floor bedding) or has beds.

7. 🙏 Culture & Etiquette Worth Knowing

• No tipping: No tips needed at restaurants, taxis, or hotels — they're often politely declined or returned. Some upscale restaurants include a service charge, but no extra tip is expected.

• At restaurants: Water and basic side dishes (banchan) are usually free with refills. Water and utensils are often self-serve — utensils may be in a drawer under the table! Press the call bell on the table or say "jeogiyo~" (excuse me) to call staff. Some BBQ and hot-pot places don't seat solo diners.

• Floor seating & shoes: Remove your shoes at hanok, traditional restaurants, and homes. A shoe rack at the entrance is your cue.

• Subway & public etiquette: Priority seats are left empty even when free. Keep calls and conversations quiet on trains; standing two abreast without walking is encouraged on escalators. Avoid strong-smelling food on subways and buses.

• Trash & recycling: Street trash cans are scarce. Use bins at convenience stores, stations, and cafés, and follow recycling rules.

• Drinking & smoking: Smoking is allowed only in designated areas — smoking in no-smoking zones can be fined. Alcohol may be restricted in some public spaces like parks. You may be asked for your passport (ID) when buying alcohol or tobacco.

• Photos: Ask before photographing café or shop interiors and people. Photography is prohibited in some military and airport areas.

8. 🚨 Safety & Emergencies — Numbers to Remember

• 1330 Korea Travel Helpline: 24/7, year-round, in English, Japanese, Chinese, and more — travel info, interpretation, and complaint support. You can even call for three-way interpretation when you can't communicate at a restaurant. The most reliable number a traveler can have.

• Emergency calls: Police 112, fire/ambulance 119. Both offer interpreter connections.

• Emergency alerts: Korean phones receive loud government disaster alerts (heavy rain, heat waves, earthquakes) in Korean. Don't be alarmed — install the 'Emergency Ready' app for the same information in English.

• Medical care: Many large hospitals have international clinics with English support. For minor issues, pharmacies (green cross sign) can advise and sell OTC medicines. Medical costs can be high — buy travel insurance before departure.

• Lost passport: Report the loss at the nearest police station, then get a travel document at your embassy or consulate. Carrying a passport copy and spare photos speeds things up.

• Safety: Korea is considered quite safe even late at night — locals commonly leave laptops to hold café seats. Still, watch your belongings in crowded nightlife areas, and always use crosswalks — jaywalking is dangerous.

❓ FAQ — What Foreigners Ask Most

Q1. Do I need to apply for a K-ETA? → It depends on your nationality. Many countries, including the US, Canada, and Japan, are temporarily exempt through December 31, 2026. Check your status on the official site www.k-eta.go.kr before departure. Note: if you're exempt and enter without a K-ETA, you may need to submit an e-Arrival Card — while travelers holding a valid K-ETA are exempt from the arrival card.

Q2. When and how do I submit the e-Arrival Card? → From 3 days before arrival (Korea time), free of charge, on the official site www.e-arrivalcard.go.kr. You'll enter your name, passport number, flight, and accommodation address. If submitted electronically, no paper arrival card is needed.

Q3. How much English is spoken? → Airports, hotels, major attractions, and large stores handle English well. Local restaurants, markets, and taxis may not — use Papago and the 1330 helpline. Showing your destination's Korean address on screen is the most reliable way.

Q4. How much cash should I bring? → Cards work almost everywhere, so 100,000–200,000 KRW as a reserve is often enough (for reference). Bring more if you plan to visit traditional markets or top up T-money with cash.

Q5. Is Google Maps enough? → You can use it, but walking and driving navigation has been limited in Korea, and features may keep changing even after the 2026 policy shift. Definitely install NAVER Map (Korean/English/Japanese/Chinese), with KakaoMap (English) as a backup. Both are free.

Q6. Can I drink the tap water? → Korean tap water meets drinking standards, but most travelers and locals drink bottled or filtered water. Convenience-store bottled water is cheap and everywhere. Free water served at restaurants is filtered — no worries.
