10-minute walk from T, P8 Outdoor is the cheap lot
P8 Outdoor sits about 800–900 meters from the Oslo Airport (OSL) terminal T, so you’re looking at roughly a 10-minute walk at a normal pace. It’s an open-air, budget car park with basic facilities: marked bays, lighting, and payment machines, but no covered parking. You park yourself, keep your keys, and head straight toward the terminal on the signposted pedestrian route.
Pricing at P8 Outdoor usually undercuts the closer garages like P1 and P10 by a noticeable margin, especially on multi-day and week-long stays. It’s set up for people leaving their car for several days or more, not a quick pickup. Prebooking online through Avinor typically locks in a better daily rate than drive-up, and you’ll see P8 specifically listed as an “outdoor” budget option in the booking flow.
P8 Outdoor is fully outside, which matters in winter when OSL temperatures often drop below 0°C and snow piles up. Expect to scrape windows if you return in January at 06:00. The lot is plowed, but individual spaces can be slushy or icy, so good boots help. There’s no direct shuttle from P8 because the walking distance to T is short enough that Avinor treats it as walk-in parking.
Access is straightforward: the entry barrier reads your license plate and ties it to your online booking, or prints a ticket if you pay on exit. Payment machines at the lot accept cards and common mobile options, and Avinor’s system bills per started 24-hour period. If your return flight into OSL runs late past midnight, expect the system to tack on an extra day.
Tip: in winter, leave a snow brush in the car and add 10 extra minutes to dig out before your drive from Gardermoen back toward Oslo.
