It is a short grass airstrip built across a hilltop, next to the village of Arongbwaratu. Sara does not suffer from the problems of waterlogging that formerly afflicted Lonorore, Pentecost's other airport, although the airport's high location makes it vulnerable to disruption in windy weather. Since the 2008-2009 upgrading of Lonorore, Sara has declined slightly in importance, although it remains a valuable transport link for the communities of northern Pentecost, since the journey from this part of the island to Lonorore by road or sea is arduous and expensive.
Sara is the word for "field" in Raga language. Locals may refer the airstrip as saran plen ("field of planes") to avoid ambiguity.
