The name Sliddery is thought to have been derived from the Gaelic denoting dragging or trailing, but another story has it that it was here that a band of marauding Vikings were butchered when attempting to settle in Sliddery Water valley and that the name has something to do with slaughter or massacre.

Nowadays, the hamlet sits upon the hill high above the estuary, about 1⁄2 mile (800 metres) from the shore. Various lanes lead down to a pebble beach, which offers views across the Kilbrannan Sound to Ireland and Ailsa Craig.
