St Barts Airport (SBH) thrills aviation enthusiasts with its dramatic 650-metre runway with one of the world's most challenging approaches. Landing aircraft must dive steeply right after clearing the hillside, then immediately pull up just a few seconds before touching down. The distance between the edge of the hill and the plane can be less than two meters! Prime viewing spots include St Jean Beach (where planes appear to skim sunbathers), the western runway perimeter, and the airport terminal cafeteria with its panoramic windows. For a grand perspective, the hills east of St Jean Bay frame the runway against turquoise waters. Note: never linger directly beneath flight paths — these low-flying aircraft leave no margin for error.
