Gimpo’s “Lot B” barely shows up online, but it exists
Long-term Parking Lot B sits in the main airport parking area at Gimpo International Airport (GMP), signed on-site in Korean as an economy long‑stay option. It serves both the International and Domestic terminals via the airport shuttle or a 5–15 minute walk depending on your row. Think of it as the cheaper, further‑out section compared with the closer short‑term decks by each terminal.
This is an economy lot set up for trips running several days or more, with daily pricing that undercuts the short‑term structures next to the International and Domestic buildings. Exact won amounts change often, but Lot B is in the long‑term tariff band, while the terminal garages charge higher hourly rates that spike quickly after the first 2–3 hours. If you plan to leave the car for a full 24 hours or longer, Lot B usually works out cheaper than the terminal decks.
Gimpo’s parking system leans on attendants, tickets, and automated machines, and forum posts going back to 2015 call out stress around Korean‑only signs and handing over keys. Expect Korean language on most signage, machines near the exits, and staff who may not speak English fluently. Budget an extra 10–15 minutes before your flight for finding the correct entrance to Lot B and paying at a kiosk before you drive out.
Watch out for traffic on the approach roads between central Seoul and GMP; one Seoul‑based poster flatly says visitors who dislike local driving habits often skip rental cars altogether. If you are not confident with Korean road signs, snap photos at each step: the Lot B entrance sign, your row marker, and the pay machine screen. Final tip: park close to a shuttle stop or pedestrian exit, then pin that spot in your maps app before you roll your suitcase away.
