Traveling from Incheon Airport to Hongdae has become significantly easier in recent years, but first-time visitors often wonder which transportation method is the most convenient choice. After spending many years living in Australia and traveling frequently back to Korea, I’ve learned that the journey from the airport to central Seoul can feel completely different depending on your energy level, travel style, and familiarity with the Korean public transportation system. Hongdae remains one of the most popular destinations, thanks to its vibrant nightlife, charming cafés, stylish boutiques, and youthful, creative culture, making it an ideal first stop for visitors. In this guide, I combine practical information, personal experiences, and a touch of comparison between Korea and Australia to help you decide the best route for your arrival.

Main Route Options from Incheon Airport to Hongdae

1. AREX All-Stop Train

The AREX All-Stop Train is the most balanced option for travelers seeking comfort, predictable travel times, and a reasonable fare. This train stops at every major station between Terminal 1, Terminal 2, and Hongdae (Hongik University Station), taking around 55 minutes.
During my flights back from Sydney or Melbourne, I always preferred the All-Stop Train because of its dedicated luggage racks—something I wished Australian trains would adopt more widely. Korea’s transit system tends to consider long-distance travelers, making the journey feel smoother, even when you’re tired from a long-haul flight.

2. AREX Express Train (Transfer at Seoul Station)

The Express Train runs nonstop from Incheon Airport to Seoul Station, cutting travel time slightly. However, since Hongdae isn’t a stop on the Express line, you need to transfer to Line 2 at Seoul Station.
In my experience, this option works best when you want to avoid crowds and get into the city quickly. Transfers in Korea are generally well-marked, but after spending over 10 hours on a plane, even well-designed stations can feel overwhelming. Compared with Australia—where major stations often have fewer multilingual signs—Korean stations feel more intuitive, but still require some alertness.

3. Seoul Subway (Line 2 Transfer Route)

Technically, you can skip AREX and use regular subway routes to reach Hongdae, but I don’t recommend this for first-time visitors with luggage. Seoul’s subway network is massive, fast, and reliable, but also busy and complex.
When I first moved to Australia, I was surprised at how uncluttered rail maps looked compared to Korea’s. Seoul’s network is efficient but can be visually overwhelming to new travelers.

4. Taxi or Airport Taxi

If convenience is your top priority, a taxi is by far the easiest choice. The journey takes approximately 45–70 minutes, depending on traffic.
There have been days when I landed in Korea physically exhausted from long flights across the Pacific, and a taxi felt like the only sensible option. Korean taxis are significantly more affordable than Australian airport taxis, especially over long distances. If you’re traveling with heavy bags or as a family, a taxi may actually be the most efficient option.

Step-by-Step Guide: Taking the AREX All-Stop Train

Buy Your Ticket

Follow the blue AREX signs after exiting the arrival hall. Ticket machines support multiple languages and accept most international credit cards. If you already have a T-money card, you can simply tap in without buying a separate ticket.

Don’t have a T-money card yet?
A T-money card makes subway, buses, and even convenience store purchases far easier.
Where to buy it at Incheon Airport:

CU convenience store (Arrivals Floor, both Terminal 1 & 2)
7-Eleven (Arrival Hall exits between Gate 5–7)
Airport Metro Station vending machines

Board the Train

Each train car includes luggage racks and space for large suitcases. One cultural difference I noticed between Korea and Australia is how willingly passengers make room for travelers with bags. It creates a more welcoming environment, especially when you’re coming straight from a long flight.

Arrive at Hongik University Station

Hongdae is directly accessible from the AREX line. Once you arrive, you’ll see multiple exits leading to the nightlife streets, cafés, dessert shops, and indie boutiques. If you’re carrying bulky luggage, use Exit 3 or the dedicated elevator near the platform.

Travel Tips From Experience

Time Your Journey

Late afternoons and Sunday evenings are noticeably crowded. One advantage Korea has over Australia is train frequency—AREX departures are predictable and frequent, reducing long waiting times.

Use Local Navigation Apps

Google Maps is unreliable inside Korean subway stations. KakaoMap or Naver Map performs far better for transit navigation. In Australia, Google Maps dominates daily life, but in Korea, local apps are essential.

Avoid Overpacking

Hongdae’s lively streets are not ideal for dragging huge suitcases. After one exhausting arrival from Melbourne years ago, I learned that packing light—or taking a taxi—makes a world of difference.

Cost Breakdown for 2025

• AREX All-Stop: Budget-friendly, consistent schedule
• AREX Express: Slightly higher cost
• Taxi: Highest cost but unmatched comfort

If price is your priority, choose AREX. If comfort matters most, choose taxi.

Korea vs. Australia: What to Expect as a Traveler

Having traveled frequently between both countries, I can confidently say Korea offers a smoother airport-to-city public transit experience. Korean signage, bilingual announcements, and short train intervals make navigation easy.
By contrast, Australian airport trains—while clean and well-managed—tend to have lower frequency and fewer luggage-friendly compartments. Travelers who expect Australian-style layouts may be pleasantly surprised by Korea’s efficiency.
