The bay is about 28 kilometres (17 mi) long with a shoreline extending 107.3 kilometres (66.7 mi). It is surrounded by two massifs of the Dinaric Alps: the Orjen mountains to the west, and the Lovćen mountains to the east. The narrowest section of the bay, the 2,300-metre (7,500 ft) long Verige Strait, is only 340 metres (1,120 ft) wide at its narrowest point.[2] The bay is a ria of the vanished Bokelj River, which used to flow from the high mountain plateaus of Mount Orjen.
