Barra Airport — Eoligarry, United Kingdom

Barra Airport occupies a wide tidal beach at Traigh Mhòr near Eoligarry, on the Isle of Barra in Scotland's Outer Hebrides. It is widely cited as the only airport in the world with scheduled flights that land directly on sand, with the tide timetable dictating departures rather than the reverse. The field sits just 5 feet above sea level, and three runways are marked out across the beach itself, their orientation shifting with the sand. BRR handles small turboprop aircraft on short regional routes, connecting Barra's island community to Glasgow whenever the tide and weather both cooperate.
