Stopover in Seoul: what to do and when to leave

Incheon is a large hub with very good airside services, but it is far from central Seoul. Hongdae is the most realistic urban exit by AREX; For palaces or historic neighborhoods you need a very large stopover and a determined railway route before leaving.

Calculate my scale

With less than 8 hours, stay at ICN. From 9–11 hours Hongdae can fit if you can enter Korea, the luggage continues to the destination and you reserve three hours to return. The historic center requires 12 hours or more.

Frequently asked questions

Before deciding

Can I leave Incheon during a layover?

Yes, if you meet the entry requirements to Korea, your luggage continues to your destination and you have enough time to return to your terminal, pass security and reach the gate.

How long does it take from Incheon to Hongdae?

The AREX arrives at Hongik University in around an hour depending on the service; Add immigration, access to the platform and the walk to the area you want to visit.

What to do with a 10-hour layover in Incheon?

Hongdae and the Gyeongui Line Forest form a more controllable urban exit. If the margin is reduced, ICN rooms and services are the safest plan.
