Laggan is located on the Hebridean island of Islay on the west coast of Scotland. The Laggan Peninsula is situated on the eastern shore of Loch Indaal, a sea loch, and comprises the rocky headland of Laggan Point and the land backing Laggan Point and Laggan Bay. The bay is an 11-kilometre long sandy sweep open to the Atlantic. This is backed by a rare and uninterrupted habitat transition from sand dunes and intertidal rocky shore habitats through acidic dune grassland, coastal heath and ultimately to blanket bog. The blanket bog is used as a roost by wintering Greenland White-fronted GooseAnser albifrons flavirostris. Intensively managed farmland on the site is an important feeding area for wintering Greenland Barnacle Goose Branta leucopsis. Goose using this site as a feeding area also use roosts elsewhere (including Bridgend Flats SPA for Greenland Barnacle Goose and Eilean na Muice Duibhe SPA for Greenland White-fronted Goose).
