Seoul Public Transportation Guide for Indians: Subway, Bus, T-money, Taxi & KTX (2026)
Everything you need to move around Seoul like a local — from getting off the plane at Incheon to riding the subway daily, taking KTX to Busan, and navigating with the right map app.
Reading time: ~14 min | Updated: April 2026
Seoul has one of the world's best public transport systems — and as an Indian expat, you'll rely on it heavily from day one. The metro covers virtually every corner of the city, buses fill the gaps, and the T-money card ties it all together with automatic transfer discounts. Once you understand the basics, getting around Seoul is genuinely easy and very cheap by Indian standards.
This guide covers everything in order: how to get from the airport on Day 1, how the T-money card works, subway and bus basics, taxis, the Climate Card monthly pass, KTX for weekend trips, and — critically — which map app to use (it's not Google Maps).
One thing to have ready before you use any transport: a funded Korean bank account for loading your T-money card. See our Korean Banking Guide for Indians (2026) if you haven't set one up yet.

1. Day 1: Getting from Incheon Airport to Seoul
Incheon International Airport (ICN) is 52 km west of central Seoul. You have four options — choose based on luggage, budget, and time of arrival.
| Option | Route | Cost | Time | Best For |
|---|---|---|---|---|
| AREX Express | Incheon T2/T1 → Seoul Station (non-stop) | ₩11,000 | 43 min (T1) / 51 min (T2) | Best overall — fast, cheap, luggage racks available |
| AREX All-stop | Incheon → Hongdae, Digital Media City, Susaek, Seoul Station | ₩4,150–₩4,750 | 66–70 min | Budget travellers; stops in Mapo / Hongdae area; T-money accepted |
| Airport Limousine Bus | Various routes to hotels, districts (Gangnam, Jamsil, Itaewon) | ₩12,000–₩19,000 | 60–90 min (traffic-dependent) | Heavy luggage; direct drop near your apartment; Gangnam / Itaewon bound |
| Taxi (regular) | Door to door; metered + expressway tolls | ₩55,000–₩100,000 | 50–75 min (no traffic) | Late night arrivals; families with young children; company relocation |
Arriving at Gimpo Airport (GMP)
Some Air India and IndiGo flights arrive at Gimpo (Gimpo International), which is much closer to Seoul (15 km west of the city centre). Take Seoul Metro Line 5 or Line 9 directly into the city from Gimpo Airport station — basic fare ₩1,550, journey to Yeouido ~15 minutes. No AREX needed.
2. T-money Card: Korea's Essential Transit Pass
The T-money card (티머니) is a rechargeable contactless card that works on almost all public transport in Seoul and most of Korea — subway, bus, taxi, and even some convenience store purchases. It is the single most important item to have in your wallet for daily life in Korea.
| Item | Details |
|---|---|
| Where to buy | Any CU, GS25, 7-Eleven, or emart24 convenience store; airport, subway station gift shops |
| Card price | ₩2,500–₩4,000 (refundable deposit if you return the card at a subway service centre) |
| Where to top up | Convenience stores (cash or card); subway station top-up machines (cash only at most); some machines now accept foreign credit cards (2026 update) |
| Discount vs cash | ₩100 per trip cheaper than cash fare |
| Transfer discount | Subway → Bus or Bus → Bus within 30 minutes: free or reduced fare transfer. Bus → Bus of same type: free. Tap out is required to activate the transfer discount. |
| Negative balance | You can exit with up to −₩500 balance; top up at next station. Beware of getting stuck with low balance at exit gates. |
| Digital T-money | Samsung Pay (Samsung phones) and certain Korean bank apps support NFC-based T-money. iPhone users: Apple Pay launched in Korea 2023 but T-money integration is still limited — physical card recommended. |
3. Seoul Subway: Lines, Fares & Navigation
Seoul Metro has 9 main numbered lines plus several additional lines (Gyeongui-Jungang, Sinbundang, Bundang, etc.) — over 20 lines in total covering Greater Seoul and the satellite cities of Suwon, Incheon, and Bundang. Each line is colour-coded and numbered consistently across all maps and apps.
Key Lines for Indian Expats
| Line | Colour | Key Stops for Indians | Why It Matters |
|---|---|---|---|
| Line 2 | Green | Hongdae, Sinchon, Ewha, Gangnam, Seolleung, Sindorim | The circular workhorse of Seoul; connects Mapo to Gangnam; busiest line |
| Line 6 | Brown | Itaewon, Hangang-jin, Mapo, Noksapyeong | The Itaewon–halal food line; serves the main Indian expat neighbourhood |
| Sinbundang (신분당선) | Red | Gangnam → Yangjae → Pangyo → Jeongja (Bundang) | Fastest route to Pangyo Tech Valley; heavily used by Indian IT professionals. Slightly higher fare (~₩2,600+) |
| Line 4 | Sky Blue | Seoul Station, Myeongdong, Dongdaemun, Sungsin Women's Univ | Connects AREX at Seoul Station; passes Dongdaemun (Indian fabric market) |
| AREX (공항철도) | Blue | Incheon Airport T1 / T2 → Gimpo → Hongdae → Seoul Station | Airport connector; all-stop train accepts T-money |
2026 Subway Fares
| Distance | T-money Fare | Cash Fare | INR Equivalent (T-money) |
|---|---|---|---|
| Basic (0–10 km) | ₩1,550 | ₩1,650 | ~₹96 |
| +5 km (10–50 km) | +₩100 per 5 km | +₩100 per 5 km | ~+₹6 per bracket |
| +8 km (over 50 km) | +₩100 per 8 km | +₩100 per 8 km | ~+₹6 per bracket |
| Example: Itaewon → Gangnam (Line 6→2, ~8 km) | ₩1,550 | ₩1,650 | ~₹96 |
| Example: Seoul Station → Pangyo (Sinbundang, ~27 km) | ~₩2,750 | ~₩2,850 | ~₹170 |
Source: Seoul Metropolitan Government, April 2026. Compared to Delhi Metro (₹10–₹60), Seoul subway is roughly 1.5–2× more expensive — but covers far greater distances with greater frequency and reliability.
Subway Etiquette (Unwritten Rules That Matter)
- Priority seats (노약자석): The seats marked in pink or with a symbol are reserved for elderly, pregnant, and disabled passengers. Do not sit in them even when the car is empty — Koreans rarely sit in them, and you will attract attention if you do.
- Phone calls: Avoid phone calls on the subway. Texting and earphones are universal; loud calls are considered rude. Use the subway vestibule area between cars if you must call.
- Backpack etiquette: Move your backpack to the front of your body in crowded cars — this is widely expected and you'll see others doing it during rush hour.
- Rush hours: 07:30–09:00 and 18:00–20:00 are extremely crowded on Lines 2, 4, and 9. Budget an extra 5–10 minutes and stand well back from platform edge markings until the train stops completely.
4. Bus System: Colour Code Explained
Seoul buses are colour-coded by function — the system is logical once you know the four colours. All buses use T-money; from 2023 onwards, Seoul buses are progressively going cash-free. Always board at the front and tap your T-money card.
🔵 Blue — 간선버스 (Trunk)
Major arterial routes crossing the whole city. Fast but fewer stops. Route numbers start with 1, 2, 3, 4, 7. Fare: ₩1,550 (T-money).
🟢 Green — 지선버스 (Branch)
Shorter routes connecting neighbourhoods to subway stations. Higher frequency, more stops. Route numbers start with 0, 2 (four digits). Fare: ₩1,450.
🔴 Red — 광역버스 (Wide-Area)
Express routes to satellite cities: Suwon, Incheon, Bundang, Ilsan. Limited stops, seated passengers only. Fare: ₩2,900+. Great for Pangyo commuters from Seoul.
🟡 Yellow — 순환버스 (Circular)
Loop routes in central Seoul. Useful for short cross-city hops (Jongno, Myeongdong area). Less common but useful for tourists. Fare: ₩1,300.
Night Owl Bus (올빼미버스 / N-bus)
Seoul's night bus network (routes starting with "N") runs from midnight to 05:00 on 9 key routes when the subway is closed. Fare: ₩2,500. Particularly useful if you're living in Itaewon, Hongdae, or Gangnam after a late night out. Check Naver Maps for the nearest N-bus route to your home.
5. Taxis: KakaoTaxi, UT & Night Fares
Korean taxis are metered, regulated, and generally honest — you will not face the auto-meter fraud that is common in India. However, a language barrier can cause problems when giving addresses. Always use an app.
| App | Language | Payment | Best For |
|---|---|---|---|
| Kakao T (카카오T) | Korean / limited English | Korean cards, KakaoPay (foreign cards sometimes work via Kakao Pay setup) | ~90% market share; fastest pickup; most drivers available |
| UT (Uber Korea) | English ✅ | International credit/debit cards ✅ | Best for Indians — linked to your existing Uber app; familiar interface; foreign card payment |
| k.ride | English ✅ | International cards ✅ | New foreigner-focused app; English-speaking drivers; growing in Seoul |
Taxi Fares (Seoul, 2026)
| Type | Base Fare | Per km | Night Surcharge | Notes |
|---|---|---|---|---|
| Regular (일반) | ₩4,800 | ₩100 per 131m | +20% (22:00–04:00) | Silver or white cabs; most common |
| Deluxe (모범) | ₩7,000 | ₩200 per 151m | No surcharge | Black cabs; professional service; English often spoken |
| Typical trip examples | Itaewon → Gangnam (~5 km): ~₩9,000 / Hongdae → Seoul Station (~6 km): ~₩10,500 | |||
6. Climate Card (기후동행카드): Monthly Unlimited Pass
Seoul launched the 기후동행카드 (Climate Card) in January 2024, and it has become the default monthly transit pass for commuters. If you take public transport more than 40 times per month — which almost every working expat in Seoul does — the Climate Card is substantially cheaper than paying per ride.
Standard Plan
₩62,000/month
Unlimited rides on Seoul Metro (all lines), Seoul city buses (blue, green, yellow), and Gimpo Goldline. Excludes Sinbundang Line and wide-area red buses.
With 따릉이 (Bike Share)
₩65,000/month
Everything in the standard plan + unlimited 따릉이 (Seoul public bicycle) rides up to 60 minutes per trip. Great if you live near the Han River path.
Youth Discount (만 19–39세)
If you are between 19 and 39 years old and registered as a Seoul resident with an ARC, you qualify for the 청년 할인 (Youth Climate Card) at ₩55,000/month — saving ₩7,000 per month vs the standard pass. Apply at your local Jumin Center (주민센터) with your ARC and proof of Seoul residence (lease contract). Most Indian IT professionals in their 20s and 30s qualify for this discount.
Is the Climate Card Worth It?
| Monthly trips | Pay-per-ride cost (₩1,550) | Climate Card | Saving |
|---|---|---|---|
| 40 trips | ₩62,000 | ₩62,000 | Break-even |
| 60 trips (daily commuter) | ₩93,000 | ₩62,000 | ₩31,000/mo |
| 80 trips + weekend use | ₩124,000 | ₩62,000 | ₩62,000/mo |
For a standard Monday–Friday commuter taking the subway to work and back, the Climate Card pays for itself by week 3 of the month.
7. KTX & Map Apps: Weekend Trips & Navigation
KTX: Korea's High-Speed Rail
The KTX (Korea Train Express) connects Seoul to major cities at speeds up to 305 km/h. For Indian expats, weekend trips to Busan, Gyeongju, Jeonju, or Suwon are easy and highly recommended — Korea's beauty and culture extend well beyond Seoul.
| Route | Time | Standard Fare (one way) | INR Equivalent |
|---|---|---|---|
| Seoul → Busan | 2 hr 15 min | ~₩59,800 | ~₹3,700 |
| Seoul → Gyeongju | 2 hr 00 min | ~₩56,700 | ~₹3,515 |
| Seoul → Daegu | 1 hr 40 min | ~₩42,600 | ~₹2,640 |
| Seoul → Jeonju (ITX) | 1 hr 50 min | ~₩22,700 | ~₹1,410 |
Book KTX via the Korail Talk app (iOS/Android) or at letskorail.com. The app has an English interface. Foreign credit cards are accepted. Book at least 1 month ahead for weekend trips — popular routes sell out fast. Note: Avoid third-party booking sites that add fees; book directly with Korail.
🗺️ Map Apps: Naver Maps vs Google Maps
This is one of the most important practical tips in this guide: use Naver Maps, not Google Maps, for navigation in Korea.
| Feature | Naver Maps | Google Maps |
|---|---|---|
| Walking directions | ✅ Accurate; includes underground passages | ❌ Often incorrect; misses underground shortcuts |
| Real-time bus arrival | ✅ Live, accurate to the minute | ⚠️ Improving but still delayed vs Naver |
| Restaurant / business info | ✅ Korean reviews, hours, menus, photos | ⚠️ Incomplete for smaller local businesses |
| English interface | ✅ Full English mode available (2023 update) | ✅ Full English |
| Subway transfer routes | ✅ Shows exact exit number and in-station path | ⚠️ Station exits sometimes wrong |
| Traffic / driving | ✅ Best for Korean roads; integrates with Naver's speed camera database | ⚠️ Usable but not as precise |
Practical setup: Download Naver Maps, set language to English, and add it to your home screen. Use it instead of Google Maps for all Korean navigation. You can still use Google Maps for international research (finding flight times, hotels outside Korea), but for anything within Korea, Naver Maps is significantly better.
Kakao Maps is the other major Korean mapping app and is excellent for taxi hailing integration with Kakao T — but Naver Maps is more accurate for public transport routing. Most Indian expats use Naver Maps as their primary and Kakao T for taxis.
Final Thought
Seoul's public transport is genuinely world-class — punctual, clean, cheap, and remarkably extensive. Once you have a T-money card, Naver Maps, and UT installed on your phone, getting around will feel second nature within a week. The Climate Card unlocks real savings from month one, and KTX makes weekend travel around Korea genuinely easy and affordable.
The only real adjustment for Indians is the tap-out discipline — never forget to tap out on both subway and bus. Set it as a habit from day one and you will never lose money to missed transfer discounts or maximum-fare charges.
