Korea Travel Essentials
Visa rules, ATM strategy, transport cheat sheets, SIM cards, safety tips, packing lists, and the cultural etiquette that turns a good trip into a great one.
↓
I've made every mistake in this guide at least once — from missing the last subway to navigating menus with zero Korean. After years of Korea travel, I've figured out the practical side so you don't have to learn the hard way. This is the cheat sheet I wish someone had handed me on my first Seoul trip.

Visa & Entry Requirements
5 tips30-Day Visa-Free
Citizens of 150+ countries (including USA, UK, Canada, Australia, EU, Japan, South Korea) can enter South Korea visa-free for 90 days. You just need a passport valid for at least 6 months and a return or onward ticket.
Extending Your Stay
Visit any Korea Immigration Service office — main branches are in Seoul (Mok-dong, Yangcheon-gu), Busan, Incheon, Daegu, Gwangju, and Daejeon. A 30-day extension costs around 60,000 won (about $45 USD). Bring your passport, accommodation address, and the application form. You can also apply online through Hi Korea at hikorea.go.kr.
Documents to Carry
Always lock your passport in your hotel safe when you are out exploring — carry a photocopy on your phone or on paper instead. Hotels will ask for your passport at check-in, but after that it should stay locked up. KTX trains and domestic flights to Jeju accept a Korean ID or passport at the gate; bring your passport along on travel days.
K-ETA Registration
Most visa-free visitors must apply for K-ETA (Korea Electronic Travel Authorization) online at k-eta.go.kr at least 72 hours before departure. Cost is 10,000 won (about $7 USD), valid for 3 years and multiple entries. As of 2026 some nationalities have a K-ETA exemption (USA, UK, Canada, Japan, Australia, EU) — always check the current list before applying.
Global Entry / SENTRI
If you're a US citizen, get Global Entry or a SENTRI pass before your trip — it's about $120 for five years and worth every penny. We got ours living in SoCal for the Mexico border crossings, but the real payoff is coming home through ICN or any international airport. After 20+ hours of travel, three or four jumbo jets land at the same time and the immigration line is massive. Global Entry gets you through in minutes instead of an hour-plus. It pays for itself after two trips.
Money & ATMs
6 tipsATM Strategy
Use bank ATMs from KB Kookmin, Shinhan, Woori, KEB Hana, or NongHyup — they reliably accept foreign cards and have English menus. Look for the Global ATM logo. Withdraw the daily max (typically 1,000,000 won, around $750 USD) to minimize the 3,500–4,500 won fee per transaction. A Fidelity Cash Management or Charles Schwab card reimburses ATM fees and saves real money on a 2-week trip.
Split Your Cards
ALWAYS bring two or three ATM cards and credit cards on your trip. Only carry one of each when you go out — keep the backups locked in your hotel safe. South Korea is among the safest countries in the world, but cards still get lost or eaten by ATMs, and if you lose your only card while traveling, your trip stops cold. We learned this the hard way.
Card Is King
Korea is the most cashless country in the world — Visa/Mastercard contactless and Korean credit cards work almost everywhere, including taxis, vending machines, traditional markets, and even temple donation boxes. You can travel for a week with under 50,000 won in your pocket. Keep about 100,000 won cash for small market stalls, older taxi drivers, and the occasional Tongin Market food coupon machine.
KakaoPay, Naver Pay, Toss
Three Korean mobile wallets dominate. Foreign tourists generally cannot register without a Korean phone number and Resident Registration Number, so stick with international credit cards or contactless Apple/Google Pay — they work everywhere KakaoPay does.
Daily Budget Ranges
Backpacker: ₩40,000–70,000/day ($30–50 USD) — hostels, street food, public transport. Mid-range: ₩100,000–180,000/day ($75–135 USD) — hotels, restaurants, private tours. Luxury: ₩300,000+/day ($225+ USD) — design hotels, fine dining, private guides. Search Agoda for hotels — Agoda is the dominant booking platform across South Korea hotels and has stronger Jeju and Busan inventory than Western competitors.
Exchange Tips
KEB Hana Bank and Shinhan Bank have the best exchange rates in Korea. Airport exchange counters (Incheon arrivals hall, ground floor) are actually competitive — better than most hotel rates. Never exchange money with street changers. Myeongdong in Seoul has the highest concentration of licensed money changers and often the best street-rate deals.
Getting Around
6 tipsDomestic Flights
Korean Air, Asiana, Jeju Air, and Jin Air connect Seoul (GMP) to Busan, Jeju, and other domestic cities. Jeju Island requires a short 1-hour flight or overnight ferry from Busan. Book 1–3 weeks ahead — domestic fares are reasonable. Jeju Air and T'way offer budget options. Search Traveloka to compare Korean Air, Asiana, Jeju Air, Jin Air, and T'way fares with hotel bundles.
KTX Bullet Trains
The KTX connects Seoul to Busan in 2.5 hours, Gwangju in 1.5 hours, and most major cities. KORAIL app handles booking. Fares run ₩30,000–60,000 ($22–44 USD) for standard seats. First class (KTX special) is affordable and worth it for the extra comfort. The train station in Seoul is Seoul Station — central and easy to reach.
Seoul Subway
Seoul's subway is world-class — 23 lines, 400+ stations, English signage throughout. T-money card (₩3,000 deposit + load) covers subway, bus, and taxi. Base fare: ₩1,400 ($1 USD). The system runs 5:30am–midnight daily, with night buses covering the gap.
Express Buses & Airport Limousine
Express buses (gosok) and intercity buses connect every city — clean, on-time, and 30-50 percent cheaper than KTX. Seoul to Busan by bus is about 25,000 won (4 hours). The Airport Limousine bus from Incheon (ICN) to central Seoul costs 17,000 won and is often more convenient than the Airport Express train if your hotel is on the route. T-money works on all city and intercity buses.
Kakao T (Ride-Hailing)
Download Kakao T before your trip — this is Korean Uber/Grab and works in every city. Register with your international phone number. Rides run 5,000-15,000 won within most cities, and the app handles English destinations well. Regular street taxis are also cheap and metered; tipping is not expected. Avoid black premium taxis at the airport — Kakao T or the Airport Limousine bus is half the price.
Car Rental (Jeju Only)
Skip a car on the mainland — KTX, subway, and intercity buses cover everything faster than driving. Jeju Island is the exception: rent a car for 40,000-70,000 won per day. An International Driving Permit (IDP) is required. Lotte Rent-a-Car and AJ Rent-a-Car have desks at Jeju airport. Note: rental shops may ask to hold your passport as deposit — politely refuse and offer a photocopy instead. They will accept.
SIM Cards & Connectivity
4 tipsYou Probably Don't Need a Local SIM
Most US carriers now include free data and texting in South Korea — T-Mobile, Google Fi, and AT&T International Day Pass all work. Calls are usually $0.20/minute. Install KakaoTalk before your trip — this is the messaging app Koreans use for absolutely everything (hotels, tour guides, friends). WhatsApp and iMessage barely exist here.
eSIM & Local SIMs
Most newer phones are eSIM only. If your carrier does not cover Korea, KT (Olleh) and SK Telecom sell tourist eSIMs and physical SIMs at Incheon (ICN) and Gimpo (GMP) airports. Tourist SIMs run 30,000-55,000 won for 5-30 days of unlimited data. eSIMs via Airalo or Yesim start at $9 for 1 GB. SIM registration requires your passport.
Data Coverage
5G is nationwide and the fastest commercial network in the world. Coverage is excellent across all 17 provinces, including Jeju, Seoraksan trails, and the DMZ tour route. SK Telecom and KT have the broadest rural coverage; LG U+ is competitive in cities. Free public Wi-Fi works in every subway car, most cafes, and government tourist info centers.
WiFi Reliability
Wi-Fi in Korea is among the fastest and most reliable in the world. Hotel and cafe Wi-Fi typically runs 100+ Mbps. Even rural temples and the DMZ tour buses have working Wi-Fi. Your phone data is more for messaging on the move than for emergencies.
Safety & Health
6 tipsTravel Insurance
Recommended. South Korea has world-class healthcare — the best hospitals are in Seoul and Busan, and an ER visit with treatment typically runs $100-400 USD without insurance. For adventure activities (Seoraksan hiking, Hantan rafting, DMZ tours) a policy that covers medical evacuation is still smart. We use SafetyWing for every trip — affordable, covers nomads and short-trippers alike, and you can sign up even after you have landed at Incheon. Peace of mind every time we board the plane to Seoul or hop a flight down to Jeju.
Tap Water
Tap water in South Korea is technically safe and meets WHO standards in every major city, but locals overwhelmingly drink bottled or filtered water out of habit. Hotels, restaurants, and cafes provide free filtered water. A 500 mL bottle costs about 1,000 won ($0.75 USD) at any convenience store.
Hospitals & Clinics
Top hospitals: Severance Hospital (Yonsei, Seoul Sinchon), Samsung Medical Center (Seoul Gangnam), Asan Medical Center (Seoul Songpa), and Pusan National University Hospital (Busan). All have international clinics with English-speaking staff. For minor issues, walk-in family medicine clinics handle most cases for 5,000-15,000 won.
Allergies & Air Quality
Korea has high pollen and fine-dust (yellow dust from Mongolia) seasons in spring (Mar-May). The AirVisual or IQAir app shows real-time PM2.5 readings. KF94 masks are widely available at any convenience store for 1,000-2,000 won; locals wear them on bad-air days as routine. Bring antihistamines if you are pollen-sensitive.
Typhoon Season
Korean monsoon (jangma) runs late June to mid-July with daily afternoon downpours. Typhoon season is August through early October, with September peak. Coastal cities (Busan, Jeju, Sokcho) get hit hardest. Check the Korea Meteorological Administration site or the Naver Weather widget. Flights and ferries to Jeju get cancelled — always have a buffer day on either end of beach trips.
General Safety
South Korea is consistently ranked one of the safest countries in the world for travelers. You can walk anywhere at 3am in Seoul or Busan without concern. The Seoul subway runs a lost-and-found system that almost always recovers devices. Petty theft is extremely rare. Emergency number is 119 (fire and ambulance) or 112 (police).
Packing Essentials
11 tipsSunscreen
Korean sunscreens are actually world-class — some of the best formulas come from Korean brands available at Olive Young stores across the country. If you prefer your own brand, bring it from home. We use this SPF 50+; summer sun in Busan and Jeju is stronger than you expect.
Mosquito Repellent
Bring DEET-based repellent (40% concentration or higher). Local brands like OFF! are available but international brands with higher concentrations work better. Essential for summer evenings near rivers, parks, and the southern coast.
Waterproof Dry Bag
An Osprey ultralight dry bag (10–20L) protects your phone, wallet, and camera on Jeju ferry crossings, coastal day trips, and sudden monsoon downpours.
Power & Voltage
Korea uses Type C and F plugs (round two-pin, European style) at 220V — NOT 110V like the US. Your phone chargers and laptops are dual-voltage and will work fine with a plug adapter. Do NOT bring any single-voltage appliances — hair dryers, curling irons, and anything with a heating element will fry unless it's rated 110–240V. Bring a travel power strip with USB ports — Korean hotels often have limited outlets near the bed.
Rain Jacket or Poncho
Sudden showers happen year-round. A lightweight packable rain jacket beats an umbrella for hiking and city days. During the summer monsoon (Jangma, late June to mid-July) and the Aug–Sept typhoon window, rain can be heavy.
Footwear
Skip the flip-flops for walking around town — sidewalks can be uneven and one stubbed toe can ruin your day. Closed-toe Crocs or Keen Newport sandals are what we wear daily. Save the flip-flops for the beach and hotel. For coastal walks and rocky shores, strapped sandals work well. Closed-toe hiking shoes for Hallasan, Seoraksan, and other mountain trails.
First Aid & Hydration
Pack a small first aid kit — bandages, antiseptic, Imodium, and pain relievers. Bring electrolyte tablets for dehydration — the heat and humidity will drain you faster than you think. We always keep a bottle of Gatorade in the hotel fridge. You can buy Gatorade and Pocari Sweat at any 7-Eleven or convenience store across the country.
Clothing & Sun Protection
Pack lightweight UV-rated rashguards and a cooling UV hat — summer sun in Busan and Jeju is intense and you will be outside all day. Cargo shorts are a must. My cargo short system is battle-tested: 10,000 won notes in front right pocket, larger bills in right cargo pocket, one credit card in front left, phone in left cargo. Quick access at street food carts and convenience stores without digging through a wallet.
Swim & Snorkel Gear
Bring 2–3 swim trunks with pockets so they can dry between days — nothing worse than putting on a wet suit in the morning. Grab a water wallet for cash and your room key, and keep your phone dry in a waterproof phone pouch. Bring your own mask and snorkel — the rental masks at most places are scratched and leak. We use the Cressi Big Eyes Evolution mask and Cressi Supernova dry snorkel. You can rent fins anywhere. Pack water shoes for snorkeling and rocky beaches.
Plane Outfit & Layers
Wear a tracksuit or sweatsuit on the plane — the flight is 15+ hours and the cabin gets cold. It also doubles as a cool-weather layer for Seoraksan mountain hikes, Jirisan trail days, or DMZ winter tours where temps drop into the 30s-40s°F. Bring a Cabeau travel pillow for the flight — worth every penny on the Incheon red-eye.
Packing & Day Bag
Use packing cubes to organize your bag — one for clean clothes, one for dirty, one for swim gear. You'll be living out of your suitcase and moving between islands constantly. For daily exploring, a crossbody sling bag keeps your essentials accessible and secure — phone, cash, sunscreen, and water bottle all within reach without a bulky backpack.
Language & Cultural Etiquette
6 tipsBasic Korean
"Gamsahamnida" (thank you), "Annyeonghaseyo" (hello), "Eolmayeyo?" (how much?), "Eodie?" (where?), "Maekju" (beer), "Mul" (water), "Hwajangshil" (restroom). Even a few words earn massive goodwill.
Honorific Culture
Korean culture is deeply respectful of age and hierarchy. Use two hands when giving or receiving items. Bow slightly when greeting. Older Koreans may ask your age early in conversation — it establishes the social hierarchy. It's not rude, it's cultural.
Tipping Norms
Tipping is not customary in Korea and can sometimes cause confusion. Service is included. At high-end restaurants you may leave a small tip, but it is not expected. Koreans are professional and don't expect gratuity.
Temple & Palace Dress Codes
Cover shoulders and knees when visiting temples — Buddhist temples are active places of worship. Remove shoes when entering inner shrine areas. Many palaces offer hanbok rental at the entrance which grants free admission and makes for great photos.
Nunchi — Social Awareness
Koreans value "nunchi" — reading the mood and being socially aware. Speaking loudly in public, rushing through meals, or being overly demanding in restaurants is frowned upon. Match the energy of those around you and you'll be welcomed everywhere.
Regional Dialects
Standard Korean (based on Seoul dialect) is spoken nationwide. The Busan/Gyeongsang dialect has a distinctive accent. Jeju Island has its own distinct dialect, considered almost a separate language. English is widely spoken in tourist areas and all major cities.

Gear We Recommend
🎒 Gear We Recommend for South Korea
Seoul averages 20,000 steps/day for sightseers. Gyeongbokgung to Bukchon to Insadong is a serious distance. Shoes that look presentable and feel good at 15,000 steps are the essential Korea purchase.
Seoul's spring and fall evenings drop fast — 65°F afternoons turn to 45°F evenings. A packable down jacket that fits in your bag handles the swing without adding bulk.
Korea uses 220V Type C/F sockets. American plugs don't fit. Modern electronics handle the voltage automatically — you just need the physical adapter.
Seoul navigation, Naver Maps (better than Google in Korea), KakaoTalk, and photography drain your phone fast. Free charging spots exist at convenience stores, but a power bank is faster.
Day trips to Suwon Hwaseong, DMZ tours, and Bukhansan National Park call for a bag that holds layers, lunch, and your camera without looking tourist-heavy on the subway.
