P1 sits right at Gimpo, but details are scarce
Non-Korean resources barely mention P1 Parking Garage at Gimpo International Airport, but airport maps list it as the main short-term structure beside the terminals. If you’re dropping someone at the International or Domestic side and heading straight back out, P1 is the on-foot option, not a shuttle lot.
P1 is signed as short-term, so assume pricing geared to stays under 24 hours, not a week-long trip. At Korean airports, that usually means the first 10–30 minutes are cheaper, then the rate climbs steadily by the hour. If your plan is a 2–4 hour park for check-in assistance or a meal, this is the kind of garage you target.
Gimpo labels its terminals simply as International and Domestic, and P1 sits by this core cluster, so walking times are likely under 10 minutes from car to check-in for most airlines. Elevators and payment machines in Korean garages often default to Korean language, so budget an extra 5 minutes the first time you use them.
Because there are no English-language reviews for the specific P1 structure and no FlyerTalk or Reddit threads calling it out, treat it as a standard Korean airport garage: bright lighting, tight ramps, and marked pedestrian paths. If you’re sensitive about height clearance, check your vehicle’s height in meters before entering; signage at Korean garages typically lists limits like 2.1 m at the entrance.
Practical tip: snap a photo of your level and pillar number when you park in P1, and take a second photo of the nearest elevator bank sign; after a late arrival back into Gimpo, those two shots can save you 10–15 minutes of wandering.
