Stanley Harbour is a large inlet on the east coast of East Falkland island. A strait called "the Narrows" leads into Port William.
It serves the town of the same name – Stanley – as a harbour. Stanley has sprawled along the south shore of the harbour, to gain shelter from the low hill of Stanley Common. As such this is the busiest waterway of the Falkland Islands and frequently visited by cruise ships, freighters and navy vessels, although this has lessened since the building of the two airports at RAF Mount Pleasant and Port Stanley Airport. It was formerly, and still is to some extent, a repair yard for vessels damaged in South Atlantic storms, or needing to restock.
