South Korea Practical Guide: Visas, Transport, Money, and Essentials

South Korea is one of the most logistically straightforward countries in Asia for independent travelers: infrastructure is excellent, public transport runs on time, internet connectivity is ubiquitous, and crime against tourists is low. The practical challenges are language (Korean is not easy to read without study), navigation (addresses work differently), and understanding how to use the systems that make the country work.

Visas

K-ETA (Korea Electronic Travel Authorization): Citizens of 112 countries can enter Korea for tourism without a visa but must register in advance through the K-ETA system (k-eta.go.kr). The application costs ¥10,000 KRW (approximately $7.50 USD) and is valid for multiple entries over 2 years. Apply at least 72 hours before departure.

Countries included: USA, Canada, UK, EU member states, Australia, New Zealand, Japan, most Southeast Asian countries. Check the K-ETA website for the current list.

Visa exemption (no K-ETA required): Some nationalities (including most EU countries) entered an additional bilateral exemption arrangement where no application is needed for stays under 90 days. Verify your specific country’s status before traveling.

Visa on arrival: Not available for most Western nationalities — use K-ETA.

Tourist stay limit: 90 days for most K-ETA countries.

Getting to Seoul from Incheon Airport

AREX (Airport Railroad Express)

The fastest and most practical option for most visitors.

Express Train: Non-stop from Incheon International Airport Terminal 1 to Seoul Station. 43 minutes. ¥9,500. Departs every 30–40 minutes from approximately 5:20am to 11:40pm.

All-Stop Train: Stops at multiple stations including Gimpo Airport, Hongik University (Hongdae), Gongdeok, and Seoul Station. 65 minutes from Terminal 1. ¥4,750. Same operating hours.

T2 (Terminal 2): Add approximately 15 minutes to travel times; the terminal has its own AREX station.

The All-Stop Train is usually the better choice for travelers staying in Hongdae, Mapo, or anywhere served by Hongik University Station — it puts you directly on Line 2 at Hongdae without transferring.

KAL Limousine Bus (Airport Bus)

Direct bus services to hotel clusters and major neighborhoods. More comfortable than the train, slower in traffic, and requires knowing which bus goes to your area. Fares ¥17,000–18,000. Travel time varies — 60–120 minutes depending on traffic. Good option if you have heavy luggage and are staying in a hotel served by the route.

Taxi

General taxi: Approximately ¥55,000–75,000 to central Seoul (1 hour+). Metered.

Kakao Taxi / UT: App-based taxis work from Incheon — Kakao Taxi is the standard Korean equivalent of Uber. The app requires a Korean phone number for verification, which complicates first-day use.

Getting Around Korea

Seoul Subway

The Seoul Metro is extensive (9 major lines plus regional lines), reliable (trains every 2–5 minutes on major lines), and the primary way to navigate the city. Fare starts at ¥1,400 (base) and increases with distance.

T-money card: The rechargeable transit card used across Seoul (and most of Korea). Buy at any convenience store (CU, GS25, 7-Eleven) or at airport machines. Load value at station machines or convenience stores. Using T-money on the subway gives a ¥100 discount per ride vs. single-journey tickets.

T-money works on: Seoul Metro, buses, taxis (most), convenience store purchases, and in many vending machines. It is the single most useful item to acquire immediately on arrival.

How to top up: At any subway station machine (select English) or at convenience store counters. Common reload amounts: ¥10,000–50,000.

KTX (Korea Train Express)

The high-speed rail network connecting Seoul to major cities:

Route	Duration	Approximate Fare
Seoul → Busan	2h 15m	¥59,800
Seoul → Gyeongju	2h	¥56,500
Seoul → Daegu	1h 40m	¥49,600
Seoul → Gwangju	1h 30m	¥42,800

Booking: The KORAIL website (letskorail.com) sells tickets in English. Seat reservation required on KTX. Book in advance for weekend and holiday travel.

Seoul Station vs. Suseo (SRT): Most KTX trains depart from Seoul Station (Line 1/4). The SRT high-speed service from Suseo Station (in Gangnam, Bundang Line) offers an alternative for southern destinations, often with competitive fares.

Intercity Buses

An alternative to KTX for destinations not well-served by rail:

Seoul Express Bus Terminal (Gangnam, Lines 3/7/9): Buses to most major South Korean cities. Typically cheaper than KTX; slightly slower.

Dong Seoul Terminal (Gangbyeon Station, Line 2): Eastern destinations including Sokcho (for Seoraksan — this is the only option, as Sokcho has no train service).

Money

Currency: Korean Won (KRW, ₩). Exchange rates approximate:

¥1,000 ≈ $0.75 USD
¥10,000 ≈ $7.50 USD (a basic meal cost)
¥50,000 ≈ $37.50 USD (the largest banknote)

ATMs: 7-Eleven, GS25, and CU convenience stores have ATMs that accept foreign cards (look for the “Global ATM” label). Woori Bank and Shinhan Bank ATMs also work with international cards. Withdrawal limits vary; some ATMs have a ¥300,000 single transaction limit.

Cards: Visa and Mastercard are widely accepted in restaurants, hotels, and shops. Some traditional markets and pojangmacha are cash-only. Carry ¥30,000–50,000 cash at all times.

Currency exchange: The best rates in Seoul are at the Myeongdong money exchange booths (unofficial exchange offices), not at the airport. Airport exchange should only be used for immediate needs.

Tipping: Not customary in Korea. Restaurants, taxis, hotels — no tip expected and none needed. Service charges are occasionally added to hotel bills; this is the total.

SIM and Internet

SIM Cards

Available at Incheon Airport’s convenience stores and telecommunications counters immediately after customs. Three main options:

Tourist SIM cards: Available from KT, SK Telecom, and U+ in tourist SIM packages. 10-day or 30-day data SIMs (data only, no calls) run ¥25,000–45,000. Unlimited data on LTE with possible throttling after a threshold.

Full SIM with calling: Requires Korean ID or passport registration at a carrier store.

Pocket WiFi rental: Available at airport counters — useful if traveling with multiple devices. ¥8,000–12,000/day.

Korea has excellent LTE and 5G coverage nationwide, including on the subway. Connectivity is not a concern once online.

Apps

Kakao Map (카카오맵): The most accurate mapping app for Korea — more current than Google Maps for local businesses, public transit routing, and walking directions. Available in English. Download before arriving.

Naver Map (네이버 지도): Alternative to Kakao Map. Better for some transit directions. Most locals use one or the other; either is reliable.

Kakao T: The primary taxi-hailing app (equivalent to Uber). Requires Korean phone number for full registration — workaround: some roaming SIM packages provide a Korean number, or register with a local contact.

Papago: Naver’s translation app, which handles Korean significantly better than Google Translate for Korean-specific expressions and menus. Camera translation function for reading menus.

Baemin / Coupang Eats: Food delivery apps. Primarily Korean-language but functional with Papago translation for delivery to parks and accommodation.

Safety

South Korea has consistently low violent crime rates — it is one of the safer countries in the world for solo travelers including women. Specific notes:

Pickpocketing: Lower than most European capitals; still possible in crowded tourist areas (Myeongdong, Itaewon nightlife). Standard precautions sufficient.

Nightlife safety: Seoul’s nightlife areas (Itaewon, Hongdae, Gangnam) are generally safe. The Itaewon crowd crush of 2022 was an exceptional event; crowd management has been tightened.

Natural disaster awareness: Korea has an emergency alert system that sends loud warnings to all phones in an area during emergency events (typhoons, hazards). The alerts are in Korean; the tone is distinctive enough to prompt checking news in English.

Emergency numbers: 112 (police), 119 (fire/ambulance), 1330 (Korea Tourism helpline — English-speaking, 24 hours).

Language and Communication

Korean (한국어) uses the Hangul writing system, which can be learned phonetically in a few hours. Even basic Hangul reading ability significantly helps with menus, station names, and street signs.

Essential phrases:

Annyeonghaseyo (안녕하세요): Hello / good day
Gamsahamnida (감사합니다): Thank you (formal)
Juseyo (주세요): “Please give me / I’ll have this”
Eolma-yeyo? (얼마예요?): How much?
Hana, dul, set (하나, 둘, 셋): One, two, three
Masisseo-yo (맛있어요): It’s delicious

The pointing + phone calculator system works universally for prices and quantities.

Climate and Seasons

Spring (March–May): Cherry blossom season (late March–mid April). Mild, pleasant, increasingly popular — book accommodation early for cherry blossom weeks.

Summer (June–August): Hot and humid, with monsoon season (jangma) typically in late June–July. Typhoon risk in August. Summer festivals and outdoor events compensate.

Autumn (September–November): The most recommended season — clear skies, dry, temperatures 10–22°C, autumn foliage in October. Peak travel season.

Winter (December–February): Cold and dry. Seoul temperatures regularly below 0°C; ski resorts active. Crowds thin dramatically; accommodation prices lower.

Cultural Norms

Shoes off: Remove shoes when entering Korean homes and some traditional restaurants (ondol seating). Look for the shoe removal area at the entrance.

Bowing: A slight bow (15–30 degrees) is standard greeting. Not required of foreign visitors, but always appreciated.

Drinking culture: Pouring drinks for others rather than yourself is the social norm; keeping someone’s glass empty is considered slightly neglectful. Holding your glass with two hands when receiving a drink is polite.

Elders first: At dining tables, the eldest person is served first and typically begins eating first.

Noise levels: Korean public behavior is generally louder and more energetic than Japanese; quiet train car rules exist on some lines but are less rigorously observed than in Japan.
