Orosay (Scottish Gaelic: Orasaigh) is a small tidal island in Traigh Mhòr on the north east coast of Barra in the Outer Hebrides of Scotland. It is about 30 hectares (74 acres) in extent and the highest point is 38 metres (125 ft).
Geography and etymology
Inland, the nearest settlement is Eoligarry, separated from the island by the strait of Caolas Orasaigh (English: "Sound of Orosay"). The smaller beach of Tràigh Cille-bharra ("the beach of the church of Barra") lies to the north. The islands of Fuday, Greanamul, Gighay and Hellisay lie further offshore in the Sound of Barra. The name "Orosay" is a variant of "Oronsay", from the Old Norse for "tidal" or "ebb island", found commonly in the Hebrides. For example, there are two other small Orosay/Orosaighs surrounding Barra alone. One is at grid reference NL665970 at the south eastern approaches to Castle Bay and the second at grid reference NL641971 in Caolas Bhatarsaigh east of the causeway.
Barra's airport uses Traigh Mhòr ("big beach"), also known as Cockle Strand, as a runway. Planes can only land and take off at low tide, and the timetable varies with the tides. Reputedly, this is the only airport in the world to have scheduled flights landing on a beach. The aircraft currently in operation on Barra is the de Havilland Canada DHC-6 Twin Otter, flown by Loganair on services to Glasgow and Benbecula. Traigh Mhòr also provides commercial cockle harvesting.
In the 1970s concern was expressed about the progressive deepening of Caolas Orasaigh as a possible cause of increased ponding of water on the beach runway at low tide. The problem does not, however, appear to have been serious and no action was apparently taken.
