Quick Answer
The fastest and most recommended way to get from Gimpo Airport (GMP) to Hongik University Station is by taking the All-stop AREX train to Digital Media City Station, then transferring to Seoul Subway Line 2. The total journey takes approximately 40-50 minutes and costs about ₩1,450 - ₩2,150 (approx. $1.10 - $1.60 USD). For the cheapest option, take a public bus for around ₩1,200 ($0.90 USD), but travel time can be 60-90 minutes depending on traffic.
By Train & Subway: The Step-by-Step Guide
Taking the Airport Railroad Express (AREX) combined with the Seoul Metro is the most efficient and reliable method. Gimpo Airport Station is directly connected to the domestic terminal (1F) and international terminal (B1).
Step 1: Board the AREX Train at Gimpo Airport Station
There are two AREX services from Gimpo Airport:
- All-stop Train (일반열차): Stops at all stations towards Seoul Station. For Hongik University, you MUST take this train to Digital Media City (DMC) Station. Runs every 6-12 minutes. Travel time to DMC: ~8 minutes.
- Express Train (직통열차): Goes non-stop to Seoul Station. DO NOT take this train if your destination is Hongik University, as it does not stop at DMC.
Follow signs for the “All-stop Train” or “일반열차”. Purchase a single journey ticket from the vending machines (English available) or simply tap in with a T-money card or a Discover Seoul Pass.
Step 2: Transfer at Digital Media City (DMC) Station to Line 2
Alight at Digital Media City Station (디지털미디어시티역). Follow the well-signed “Transfer to Line 2 (Green Line)” path inside the paid area. The walk takes 3-5 minutes.
Step 3: Ride Line 2 to Hongik University Station
Board Line 2 heading towards Hongdae, Sindorim, or City Hall direction (check the electronic signs). Hongik University Station (홍대입구역) is just one stop away from DMC. The ride takes about 2 minutes.

Insider Tip: If you have heavy luggage, use elevators which are abundant. During peak hours (7-9 AM, 6-8 PM), trains can be crowded.

Traveler Experience & Insider Tips
Beyond schedules and fares, here are practical insights from frequent travelers.
1. Luggage Handling Strategy
- Light Packing Wins: The train/subway transfer involves walking and stairs (though elevators exist). A backpack + carry-on is ideal.
- Luggage Storage at Gimpo: If you want to explore Hongdae area luggage-free, use the Gimpo Airport Luggage Storage Service (B1 of Int'l Terminal). Cost: ~₩3,000-₩7,000 per bag per day.
- Avoid Rush Hour (출퇴근 시간): 7-9 AM and 6-8 PM on weekdays. Trains and buses are packed, making transfers with luggage stressful.
2. Navigation & Connectivity
- Essential Apps: Download Naver Map or KakaoMap (more accurate than Google Maps in Korea). For subway navigation, “Subway Korea” is excellent.
- Free Airport WiFi: Connect to “Airport Free WiFi” at GMP for instant access to maps and schedules.
- Transfer at DMC: The transfer corridor is long but well-signed. Just follow the green Line 2 signs. Don’t exit the paid gates.
3. Money & Payment
- Cash is King for Buses/Taxis: While T-money is best, have some Korean Won in small denominations (₩1,000, ₩5,000 notes) for bus drivers or taxi fares.
- Reload T-money Easily: Reload your T-money card at any convenience store or subway station machine (English option available).
4. Special Circumstances
- Late-Night Arrival (Past 11:30 PM): AREX and public buses stop running around midnight. Your only practical options are a taxi or a pre-booked private transfer.
- Early Morning Flight: The first AREX train departs Gimpo Airport around 5:30 AM. Plan accordingly.
- Traveling with Kids/Disabilities: Taxis or airport buses are easier. All subway stations have elevators, but the transfer walk at DMC might be challenging with strollers.
FAQs: Getting from Gimpo Airport to Hongik University Station
1. Is there a direct train from Gimpo Airport to Hongik University Station?
No, there is no single direct train. You must take the AREX All-stop train to Digital Media City (DMC) Station and then transfer to Seoul Subway Line 2 for one stop to Hongik University Station. The entire process is very straightforward and well-signed.
2. What is the cheapest way to get from GMP to Hongik University?
The cheapest way is by public city bus (e.g., #6633) for only ₩1,200 (with T-money card). However, it's the slowest (60-90 mins) and least comfortable, especially with luggage.
3. How much is a taxi, and is it worth it?
A regular taxi costs approximately ₩25,000 - ₩40,000. It's worth it only if you are in a group of 3-4 (splitting the fare), arrive very late at night after public transport has stopped, or have excessive luggage/mobility issues. For most solo travelers, the train is far more economical.
4. I arrive at midnight. How do I get to Hongdae?
After about 11:30 PM, your only reliable options are a taxi or a pre-booked private transfer. Expect to pay the late-night surcharge (20%) for taxis. Do not rely on trains or buses at this hour.
5. Can I use the Japan Rail Pass for this journey?
Absolutely not. The Japan Rail (JR) Pass is only valid for travel within Japan. It holds no value in South Korea. For this route, you need a Korean T-money card or a single journey ticket.
6. Is the AREX transfer at DMC Station difficult?
No, it's very easy. The transfer is indoors within the paid area. Simply follow the abundant green signs for “Line 2 Transfer.” The walk takes 3-5 minutes. There are elevators if you have heavy luggage.
7. Should I buy tickets in advance?
No advance purchase is needed for trains or buses. Simply buy a single ticket at the station or use a T-money card. The only thing to book in advance is a private transfer van if you require one.
8. Which option is best for a family with young children?
For families, an airport limousine bus (if available for your route) or a taxi is often best. They provide door-to-door or near-door service without the hassle of navigating stations, transfers, and crowds with strollers and kids in tow.
