P4

15-minute walk buys you some of the lowest on-site prices

P4 at Brussels South Charleroi Airport sits on the far edge of the official car park zone, about a 15-minute walk from terminals T1 and T2. It is an open-air, remote economy option that the airport itself recommends for stays of more than 5 days. Think of it as the ultra-budget tier of the official lots rather than a quick-in, quick-out choice.

Pricing on P4 usually lands near the bottom of Charleroi’s on-site options and competes with off-site parks that advertise around €30–€40 per week including shuttle. The snag: you only get those savings if the online rate undercuts the private operators for your exact dates. Regulars often check comparison sites and only lock in P4 when the total beats those €30–€40 packages by more than a token amount.

P4 is online-only; the airport states you must reserve on the website before arriving at the barrier. Drive-up payment is not supported, so showing up in peak holiday weeks without a booking can leave you in front of a closed entrance even if you see empty bays beyond the fence. Charleroi forum users are blunt on this point and repeat “absolument réserver en ligne” as standard advice.

Walking time from P4 to T1/T2 runs about 15 minutes at a normal pace, with luggage in tow. There is no routine shuttle linked to the lot, so you should build that walk into your check-in timeline alongside security, which can spike past 30 minutes on summer mornings. Aim to park at least 60–75 minutes before bag-drop cut-off, and screenshot your P4 booking QR code in case mobile data drops at the gate.
