P3 Outdoor sits about 8–10 minutes’ walk from Terminal T
P3 Outdoor is the basic economy lot at Oslo Airport, Gardermoen (OSL), set up for longer trips where cost matters more than being right at the terminal. It’s uncovered, standard asphalt parking, so you get the cheaper rate but your car sits in the open year-round. Signage for P3 is clear once you follow the airport’s economy parking directions toward the main terminal area.
This lot is fully outdoor, so in January you’re scraping ice at -10°C, and in July the car can feel like an oven after a week in the sun. There are marked pedestrian paths running from P3 toward Terminal T, and most people report about 8–10 minutes on foot if you’re rolling a carry-on and not wrangling kids. If your checked bag is heavy, budget a couple of extra minutes for the walk.
P3 Outdoor usually prices below the closer garages like P10, and the savings add up on trips longer than 3–4 days. Prebooking online often locks in a lower daily rate than drive-up, especially around school holidays and peak ski-season weekends. The earlier you book for July and Christmas weeks, the more likely you are to get the cheaper tiers still available in the system.
There’s ANPR (automatic number plate recognition) at P3 Outdoor, so entry and exit tie to your registration plate instead of a paper ticket. That speeds things up at the barrier when you arrive and when you leave, especially after late-evening flights that land after 22:00. Keep the confirmation email handy on your phone in case the camera misreads your plate in heavy rain or snow.
Tip: if your return is in winter and snow is forecast, throw a small shovel and ice scraper in the boot before you park at P3 Outdoor; digging out in -5°C is easier when your own tools are in the car.
