Grimsay is the largest of the low-lying stepping-stones which convey the Oitir Mhòr (North Ford) causeway, a arc of single track road linking
North Uist and
Benbecula via the western tip of Grimsay. Until it opened in 1960, a ferry linked
Carinish (on North Uist) with Gramsdale (on Benbecula), but could only operate at high tide. East of Grimsay lie several smaller islands including
Ronay which was inhabited until 1931. ==Inhabitants==
