Saint Barts has a small airport (IATA identifier SBH) is served by small regional commercial aircraft and charters. Most visiting aircraft carry fewer than twenty passengers, such as the Twin Otter, a common sight around Saint Barths and throughout the northern West Indies. The short airstrip is at the base of a steep hill ending directly on the beach. The arrival descent is extremely steep over the hilltop traffic circle and departing planes fly right over the heads of sunbathers (although small signs advise sunbathers not to lie directly at the end of the runway). The nearest commercial jet airport is on the neighboring island of Saint Martin.
