Most SLU chatter is about flights, not the Airport Car Park
At George F. L. Charles Airport (SLU) in Castries, the on-site Airport Car Park is a basic surface lot sitting directly in front of the terminal, but almost no English-language forums talk about it. Local drivers use it for quick terminal drop-offs and short errands, since walking time from the farthest space to the check-in counters is usually under 3 minutes.
This is a ground-level surface lot with open-air spaces, not a garage, so your car sits in full Caribbean sun for hours at a time, and shade depends entirely on time of day and which row you land. The lot connects straight to the small terminal entrance, and you avoid any shuttle buses or transfers that you might see at larger airports like UVF Hewanorra, 55 km to the south.
Pricing for the Airport Car Park at SLU is not clearly posted online, and recent flyers on major forums like TripAdvisor, FlyerTalk, and Reddit leave a blank space where reviews or complaints would normally sit, which suggests locals treat it as a pay-and-go utility rather than a trip-planning decision point. Expect short-stay rates to favor quick pickups and drop-offs of under 2 hours, with daily parking more common for island residents flying to nearby islands.
Security details for the lot are not heavily documented in English-language sources, but the spaces sit within the airport perimeter directly adjacent to the main terminal, about 100–150 meters from the runway side fencing. You get passive oversight from terminal staff and other drivers at peak times when LIAT, Air Antilles, and inter-island flights cluster in the late morning and early afternoon.
Tip: Bring cash in Eastern Caribbean dollars or small USD bills, since smaller Caribbean airports like SLU sometimes have card machines offline and you don’t want to burn 20–30 minutes sorting payment right before check-in closes.
