San Carlos Airport

San Carlos Airport sits on the bay shore of the mid-Peninsula, and it's the closest general-aviation field to San Francisco proper. It's a compact, single-runway reliever field — home to flight schools, clubs, and the Hiller Aviation Museum — that keeps light traffic off the bigger Bay Area airports.

Who flies here

SQL is a general-aviation field through and through — light aircraft, training, and smaller business turboprops. Its short runway makes it a light-aircraft field rather than a jet base, but for Peninsula travelers it's convenient and uncrowded.

A bit of history

The San Mateo County-owned field has served the Peninsula's general aviation for decades and shares its grounds with the Hiller Aviation Museum, whose collection traces Northern California's long aviation history — a fitting neighbor for one of the Bay's busiest small-aircraft fields.

FBO and history details were last verified mid-2026 against the airport's and operators' own published information; tenants and amenities change, so confirm the departure terminal with your operator.
