Incheon Airport (ICN) to Gangnam: Express Bus & Subway [2026]

Distance 65 km
Fastest 65 min
From ₩5,350 ($3.90)
Top Pick K-Limousine Bus 6703 / 6009
Quick 10-Second Verdict:

For Gangnam and COEX, the K-Limousine Bus (Route 6703 or 6009) is the top choice (65–80 mins, ₩17,000–₩18,000 / $13), offering plush reclining seats and direct drop-off at major Gangnam hotels. Budget travelers can take the AREX to Gimpo Airport + Subway Line 9 Express (75 mins, ₩5,350 / $3.90).

Gangnam is located south of the Han River, approximately 65 km southeast of Incheon Airport. Because Gangnam is on the opposite side of Seoul from Incheon, taking a direct limousine bus via the southern Olympic Expressway is generally much more comfortable than making multiple crowded subway transfers.

Tickets, Luggage & Late-Night Arrivals

How Tickets & Payments Work

Buy K-Limousine bus tickets at the indoor/outdoor kiosks on 1F Arrivals (credit cards accepted). You can also tap a T-Money card or scan a pre-booked Klook bus voucher barcode directly on the bus.

Traveling with Suitcases

K-Limousine buses feature generous cargo compartments where staff load up to two large bags per person. Taking the subway with heavy suitcases requires transferring at Gimpo Airport and navigating crowded Line 9 express trains.

Arriving After Midnight

Night Bus N6000 operates hourly from Incheon T1 to Gangnam Express Bus Terminal throughout the night between 23:50 and 04:00 (₩10,000).

Common Mistakes & Airport Scams to Avoid

  • Taking a regular all-stop subway line 9 instead of the Express (Geup-haeng) train from Gimpo — express trains skip 15 stations and save 25 minutes.
  • Hiring a standard street taxi during morning rush hour — meter fares to Gangnam can exceed ₩90,000–₩110,000 due to severe traffic on the Olympic Expressway.
  • Ignore unofficial touts inside the terminal offering "VIP black taxi" services for ₩150,000–₩200,000. Use the dedicated AREX express train for ~₩11,000, buy a ticket for the official K-Limousine bus, or use the official taxi queue at curbside where standard metered rates apply.
