For travelers with a layover in Seoul, the proximity of GMP to the city center is a real gift. Getting into town takes around 60 minutes via Seoul Subway Line 5 & 9, and we’ve mapped out the logistics so you can spend less time planning and more time exploring.
What to Know Before Leaving the Terminal
Before heading into Seoul, take a moment to confirm the basics:
- Visa status: Entry rules for South Korea vary by nationality. If you’re unsure, check with your airline or the immigration desk before leaving the secure area.
- Getting there: Seoul is roughly 60 minutes from GMP via Seoul Subway Line 5 & 9. Plan to be back at the airport at least 2 hours before your next departure.
- Money: You’ll be spending in KRW. Cards are widely accepted in most places, but carrying some KRW in cash is a good idea for smaller vendors.
What to See and Do in Seoul
With limited time, focus on what’s accessible. In Seoul, two standouts are:
- Gyeongbokgung Palace — History buffs will appreciate this, and it doesn’t take long to explore the grounds.
- Myeongdong Shopping Street — Great for picking up a quick snack or souvenir between flights.
Both are realistic options even if you only have a few hours to spare.
Staying airside? That’s fine too. Inside GMP, you can spend time at Korean Air KAL Lounge (Gimpo Airport) or try Lotte Duty Free (Gimpo Airport Branch). Sometimes the best layover is a calm one.
Where to Eat
For food in Seoul, local travelers recommend Saemaul Sikdang (Hongdae). If you have time for a second stop, Kyochon Chicken (Hongdae) is another popular pick.
Back at GMP, Bibigo (Gimpo Airport Branch) is the go-to. Paris Baguette (Gimpo Airport) rounds out your in-terminal options.
Transport from Gimpo International Airport to Downtown
The most straightforward way into Seoul is the Seoul Subway Line 5 & 9, which takes about 60 minutes. This is generally the best option for layover travelers — it’s reliable and you won’t get stuck in traffic.
A taxi or ride-share will also get you there, typically in 80 minutes depending on conditions, but expect to pay significantly more. If time is tight, the Seoul Subway Line 5 & 9 is usually the smarter call.
Layover Budget Breakdown
Here’s a rough breakdown of what a quick trip into Seoul might cost in USD:
- Transport (round trip): ~$5 USD
- A meal: ~$9 USD
- Miscellaneous: ~$10 USD
- Estimated total: ~$24 USD
Budget a little extra for the unexpected. It’s better to come back with spare change than to run short.
Where to Leave Your Bags
Luggage storage is available at Luggage storage and delivery services are available at the International Terminal (1F & 2F) and Domestic Terminal (1F).. Drop your bags off early so you can explore hands-free.
Alternatively, third-party services like Bounce or Stasher can connect you with storage locations closer to wherever you’re headed in Seoul.
Staying Connected
WiFi at GMP should cover you while you’re in the terminal. Once you step outside, you’ll want your own data connection for maps, translating, and getting around. An eSIM is the simplest solution — set it up on your phone before landing in South Korea and you’re good to go.
Resting at the Airport
Not every layover involves sightseeing. If you’d rather rest, GMP has seating areas throughout the terminal, though comfort levels vary. Grab a neck pillow and stake out a quiet corner.
Airport lounges — accessible via day pass, credit card perks, or services like Priority Pass — typically offer reclined seating, showers, and a quieter environment.
Final Thoughts
There you have it — everything you need to make a layover in Seoul count. The hardest part is usually just deciding to leave GMP. Once you do, you’ll be glad you did.
Keep your flight info handy, budget a buffer for the return, and enjoy the ride.
