Seoul is one of the easiest cities in Asia to navigate, with world-class public transit, widespread English signage in tourist areas, and excellent infrastructure. Here are the practical details you need to know before arriving.
Seoul Travel Tips: Airport Transfers
Seoul has two airports. Incheon International Airport (ICN) is the main international gateway, 48km west of central Seoul. Gimpo International Airport (GMP) handles domestic flights and some regional international routes, 15km west of the city center. From Incheon, the AREX Express train reaches Seoul Station in 43 minutes for 9,500 KRW (US$7). The AREX All-Stop train (same route, more stations) takes 56 minutes and costs 4,150 KRW (US$3). Airport limousine buses (15,000-17,000 KRW/US$11-13) serve major hotels and neighborhoods; the trip takes 60-90 minutes depending on traffic. Taxis from Incheon to central Seoul cost 65,000-90,000 KRW (US$49-68) for a regular taxi, 90,000-120,000 KRW (US$68-90) for a deluxe “mobeom” taxi (black with yellow sign). International taxis with English-speaking drivers are available at designated stands in both terminals. From Gimpo, the AREX All-Stop train to Seoul Station costs 1,450 KRW and takes 22 minutes. Taxis to central Seoul are 25,000-35,000 KRW (US$19-26).
Seoul Travel Tips: Getting Around the City
Seoul’s subway system has 23 lines (including suburban rail) covering the entire metropolitan area. A single ride costs 1,250 KRW (US$0.95) with a T-money card, plus 100 KRW for every 5km beyond 10km. Buy a T-money card at any convenience store (GS25, CU, 7-Eleven) for 2,500 KRW and top it up at subway station machines. The card works on subways, buses, and even in some taxis and convenience stores. Subway announcements and signage include English. Buses are more complicated for visitors; stick to the subway unless you’re confident with Korean navigation apps. Taxis are affordable: base fare is 4,800 KRW (US$3.60) for the first 1.6km, with 100 KRW per 132 meters thereafter. A 20-minute taxi ride within central Seoul typically costs 8,000-12,000 KRW (US$6-9). KakaoTaxi is the local ride-hailing app (English interface available). Naver Map and KakaoMap are the essential navigation apps; Google Maps has limited functionality in South Korea due to government restrictions on map data export.
Seoul Travel Tips: Visa and Entry
Citizens of 110 countries can enter South Korea visa-free for 30-90 days under the K-ETA (Korea Electronic Travel Authorization) system. The K-ETA costs 10,000 KRW (about US$7.50), must be applied for at least 72 hours before departure via the official website (k-eta.go.kr), and is valid for 2 years. Check the website for your specific country’s exemption period: US, UK, EU, Australian, and Canadian citizens typically get 90 days. Citizens of countries not on the visa-waiver list need to apply for a tourist visa (C-3) at a Korean embassy. The Q-code health declaration system (a post-COVID remnant) is no longer required as of 2025, but verify current requirements before travel as rules can change.
Seoul Travel Tips: Money and Tipping
South Korea is effectively cashless. Credit cards (Visa, Mastercard) are accepted virtually everywhere, including street food stalls, convenience stores, and taxis. Carry 30,000-50,000 KRW (US$23-38) in cash for traditional markets like Gwangjang and small independent vendors. ATMs at convenience stores accept international cards with a 3,000-5,000 KRW fee per withdrawal. Tipping does not exist in Korean culture. Do not tip in restaurants, taxis, or hotels. Some high-end hotel restaurants and Western-brand hotels have started adding a 10% service charge, but this is printed on the bill and you should not add anything extra. Attempting to tip can cause confusion or even offense.
Seoul Travel Tips: WiFi and Connectivity
Seoul has the fastest and most widespread public WiFi in the world. Free WiFi is available on all subway trains and stations, in most cafes and restaurants, and at major tourist sites. However, it requires authentication via a Korean phone number in some cases. For reliable always-on connectivity, rent a portable WiFi egg at Incheon Airport (5,000-8,000 KRW/US$4-6 per day, unlimited data). Pre-order online for pickup at the airport through providers like KT Roaming or SK Telecom. Alternatively, buy a Korean SIM card at the airport (25,000-45,000 KRW/US$19-34 for 10-30 days of data). eSIM options are available through Airalo and similar providers if your phone supports eSIM. Power outlets are Type C and F (European-style two round pins), 220V/60Hz. Bring an adapter if coming from North America, the UK, or Australia.
Seoul Travel Tips: Safety
Seoul is one of the safest large cities in the world. Violent crime against tourists is extremely rare. Walking alone at night in any neighborhood, including Hongdae’s club district at 3 AM, is generally safe. Pickpocketing is uncommon but can occur in crowded areas like Myeongdong on weekends; keep your wallet in a front pocket. The main safety concern is traffic: drivers can be aggressive, and motorbike delivery drivers frequently ride on sidewalks. Look both ways even on pedestrian crossings. Emergency numbers: 112 for police, 119 for fire and ambulance. The Korea Tourism Organization runs a 24/7 English-language tourist helpline at 1330; they can assist with translation, directions, and emergency assistance. Tap water in Seoul is treated and officially safe to drink, but most locals use water purifiers or buy bottled water due to concerns about old building pipes.
Seoul Travel Tips: Etiquette and Customs
Korean social etiquette is more formal than in Western countries but locals are forgiving of foreign visitors who make mistakes. A few key points: use both hands when giving or receiving something from someone older or in a service context (business cards, cash, credit cards). Remove shoes when entering a traditional restaurant with floor seating or someone’s home. In restaurants, the eldest person at the table is served first and starts eating first. Pour drinks for others rather than yourself; hold the bottle with both hands when pouring for someone older. Public displays of affection are more restrained than in Western countries; hand-holding is fine but extended kissing in public is unusual. On public transit, the priority seats at the ends of subway cars are genuinely reserved for elderly, pregnant, and disabled passengers; do not sit in them even if the train is crowded. Koreans are direct about physical appearance and may comment on your weight, skin, or appearance in ways that feel blunt to Westerners; this is concern, not rudeness.
